Airbag and Safety Belt Pretensioner Supplemental Restraint System (SRS)

 

Principles of Operation

The RCM continuously receives/monitors all inputs from the following SRS components:

If the RCM detects sudden vehicle deceleration and/or lateral deceleration based on information received from sensors and switches and determines that deployment is required, the RCM sends voltage and current to deploy the appropriate SRS components.

The RCM contains an internal sensor that detects vehicle rollover angles. If the RCM determines that a rollover condition exists and deployment is required, the RCM deploys the applicable SRS components.

During a frontal or side crash, the RCM may deploy the following SRS components, based on crash severity and sensor input.

The fact that the safety belt buckle pretensioner(s), safety belt retractor(s) or air bags did not activate for both front seat occupants in a crash does not mean that something is wrong with the SRS . Similarly, if the vehicle is equipped with inflatable safety belts, the fact that the inflatable safety belt(s) did not activate for both second row seat occupants in a crash does not mean that something is wrong with the SRS .

The RCM performs a self-test of the complete SRS during each startup. If a SRS fault exists, the air bag warning indicator will illuminate and remain illuminated for the rest of the ignition cycle. In addition to the self-test at start up, the RCM continuously monitors all of its SRS components and circuitry for correct operation.

 

Air Bag Module Second Stage Deployment Check

Because the driver and passenger front air bags each have 2 deployment stages, it is possible that stage 1 has deployed and stage 2 has not.

If a front air bag module has deployed, it is mandatory that the front air bag module be remotely deployed using the appropriate air bag disposal procedure.

 

Air Bag Warning Indicator

The air bag warning indicator:

 

Clockspring

The clockspring allows for continuous electrical connections between the driver air bag module and the RCM when the steering wheel is turned.

 

Driver Air Bag Module

The driver air bag module is a dual-stage air bag, upon receiving a flow of current from the RCM , deploying at 1 of 2 different rates depending upon vehicle impact severity and sensor input.

Event Notification Signal

The purpose of the deployment event notification feature is to provide other vehicle subsystems with information pertaining to restraint system deployment or fuel cutoff status. Signal communication between the RCM and fuel pump control module allows the PCM to initiate fuel cut-off to disable the fuel system in the event of a crash.

 

High Speed Controller Area Network (HS-CAN)

This vehicle utilizes a communication system called a HS-CAN . The RCM communicates with various modules for required information about the vehicle. Refer to Section 418-00 for information about the HS-CAN .

 

Inflatable Safety Belts (if equipped)

Refer to Description and Operation in Section 501-20A .

 

Impact Sensors

For this vehicle line, the SRS uses 6 satellite sensors in addition to the RCM . The RCM is mounted to the center tunnel beneath the console. All vehicles have 2 front impact severity sensors located in the front of the vehicle. The first row impact sensors are mounted to each front door behind the trim panel, the second row sensors are located on each C-pillar. Mounting orientation is critical for correct operation of all impact sensors.

 

Occupant Classification System (OCS)

The OCS is found only on the front passenger seat. The OCS classifies the size of the front passenger seat occupant and provides this information to the RCM . The RCM uses this information (and other inputs) in determining the deployment strategy of the passenger air bag and pretensioner. The OCS is comprised of an OCSM and 2 OCS weight sensor bolts that are mounted to each end of the inboard seat track rail and are serviced as an assembly with the seat track. The OCSM is mounted to an electrical bracket underneath the seat and can be serviced separately. The OCSM sends information concerning the weight of any occupant or object on the front passenger seat to the RCM via HS-CAN . The RCM uses this information in determining if the passenger air bag module is to be deployed in the event of a crash.

The OCS is also used for operation of the passenger Belt-Minder®. For information on the passenger Belt-Minder® feature, refer to Section 501-20A . To deactivate or reactivate the passenger Belt-Minder® feature, refer to Section 413-01 or the Owner's Literature.

Belt Tension Sensor (BTS)

The BTS :

The BTS is used to identify the presence of a child safety seat on the front passenger seat. The BTS senses the tension on the safety belt then provides an output to the OCSM , indicating that the safety belt is cinched. After sensing the weight applied to the seat or using BTS input, the OCSM determines how the occupant should be classified and communicates this information to the RCM . If the occupant is classified as a child, the RCM then automatically deactivates the passenger air bag module and illuminates the PAD indicator.

Passenger Air Bag Deactivation (PAD) Indicator

The RCM controls the state of the PAD indicator via the HS-CAN and I-CAN . The PAD indicator state is based on information that the OCS provides to the RCM . When the passenger air bag is activated, the PAD indicator displays ON. If the RCM has deactivated the passenger air bag, the PAD indicator displays OFF.

When the ignition is first turned ON, the RCM briefly activates both the ON and OFF LEDs in the PAD indicator to prove out the indicator function and verify proper operation of the PAD indicator to the front occupants.

The following table indicates the passenger air bag and PAD indicator status based on the size of the front passenger seat occupant.



 Passenger Air Bag and Passenger Air Bag Deactivation (PAD) Indicator Status

Occupant Size Passenger Safety Belt Buckle Status Passenger Air Bag Status PAD Indicator Status
Empty Buckled/ Unbuckled Disabled OFF: Lit
ON: Unlit
Small Buckled/ Unbuckled Disabled OFF: Lit
ON: Unlit
Large Buckled/ Unbuckled Enabled OFF: Unlit
ON: Lit

 

Passenger Air Bag Module

The passenger air bag module is a dual-stage air bag, deploying at 1 of 2 different rates depending upon vehicle impact severity and sensor input.

 

Restraints Control Module (RCM)

 WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy and cause serious personal injury or death.

 WARNING: If a vehicle has been in a crash, inspect the restraints control module (RCM) and the impact sensor (if equipped) mounting areas for deformation. If damaged, restore the mounting areas to the original production configuration. A new RCM and sensors must be installed whether or not the airbags have deployed. Failure to follow these instructions may result in serious personal injury or death in a crash.

NOTE: This vehicle is equipped with the SYNC® feature which contains the 911 assist option. Refer to the Owner's Literature.

The RCM carries out the following functions:

The RCM monitors the SRS for possible faults. If a fault is detected, the RCM sends a request to the IPC to illuminate the air bag warning indicator. When the ignition is turned OFF and then ON, the IPC proves out the air bag warning indicator by lighting for 6 seconds. If no faults are detected by the RCM , the IPC turns the air bag warning indicator off and it remains off. If the RCM detects a fault, it sends a message to the IPC to turn the air bag warning indicator on. The air bag warning indicator then stays on for the rest of the ignition cycle. If the RCM requests illumination of the air bag warning indicator and the air bag warning indicator does not function, the IPC automatically activates an audible chime.

The RCM includes a backup power supply. This feature provides sufficient backup power to deploy the air bags in the event that the ignition circuit is lost or damaged during impact. The backup power supply depletes its stored energy approximately one minute after power and/or ground has been removed from the RCM .

 

Safety Belt Buckle Pretensioners and Safety Belt Retractor Pretensioners

The safety belt buckle pretensioners (driver and front passenger positions) and safety belt retractor pretensioner (driver position only) remove excess slack from the safety belt webbing. The pretensioners are activated by the RCM when the module detects a crash event force exceeding a programmed limit.

 

Safety Belt Buckle Switches

The safety belt buckles are comprised of integrated circuits called Hall-effect switches. The safety belt buckle switches indicate to the RCM whether the safety belts are buckled or unbuckled.

The RCM also communicates the driver safety belt buckle switch status to the IPC , which monitors the information to control the safety belt warning indicator. For information on the safety belt warning indicator, refer to Section 413-01 .

 

Safety Belt Adaptive Load Limiting Retractor

The front passenger safety belt retractor is equipped with the adaptive load limiting feature that works in conjunction with the safety belt buckle pretensioner to control the tension of the front passenger safety belt in the event of a crash. The front passenger safety belt retractor is also referred to as the seatbelt load limiter.

 

Safety Canopy® Module

 WARNING: Anytime the Safety Canopy® or side air curtain module has deployed, a new headliner and new A-, B-, C- and D-pillar upper trim panels and attaching hardware must be installed. Remove any other damaged components and hardware and install new components and hardware as needed. Failure to follow these instructions may result in the Safety Canopy® or side air curtain module deploying incorrectly and increases the risk of serious personal injury or death in a crash.

The Safety Canopy® module:

 

Seat Side Air Bag Module

The side air bag module:

 

Seat Track Position Sensor

The seat track position sensor is a Hall-effect sensor which indicates the position of the seat along the seat track to the RCM . The sensor detects the presence of a shunt bracket on the track, indicating that the seat has moved past a certain point in the range of adjustment. The RCM uses this information in determining the deployment rate of the dual-stage driver air bag module.

 

Secondary Air Bag Warning (Chime)

The secondary air bag warning chime is an audible chime located in and controlled by the IPC . If a fault is detected with the air bag warning indicator, a DTC is stored in memory of the IPC . Upon receiving the message from the RCM that a SRS fault has been detected, the IPC sounds the secondary air bag warning chime in a pattern of 5 sets of 5 beeps.

Pinpoint Test

 

Pinpoint Test A: DTCs B0001:11, B0001:12, B0001:13 and B0001:1A

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The RCM continuously monitors the driver air bag module stage 1 and circuits for the following faults:

If a fault is detected, the RCM stores DTC B0001:11, B0001:12, B0001:13 or B0001:1A in memory and sends a message to the IPC to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
B0001:11 Driver Frontal Stage 1 Deployment Control: Circuit Short to Ground When the RCM senses a short to ground on either driver air bag stage 1 circuit, a fault will be indicated.
B0001:12 Driver Frontal Stage 1 Deployment Control: Circuit Short to Battery When the RCM senses a short to voltage on either driver air bag stage 1 circuit, a fault will be indicated.
B0001:13 Driver Frontal Stage 1 Deployment Control: Circuit Open When the RCM measures greater than the desired resistance range between driver air bag stage 1 circuits, a fault will be indicated.
B0001:1A Driver Frontal Stage 1 Deployment Control: Circuit Resistance Below Threshold When the RCM measures less than the desired resistance range between driver air bag stage 1 circuits, a fault will be indicated.

 
PINPOINT TEST A: DTCs B0001:11, B0001:12, B0001:13 AND B0001:1A

 WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy and cause serious personal injury or death.

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test B: DTCs B0002:11, B0002:12, B0002:13 and B0002:1A

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The RCM continuously monitors the driver air bag module stage 2 and circuits for the following faults:

If a fault is detected, the RCM stores DTC B0002:11, B0002:12, B0002:13 or B0002:1A in memory and sends a message to the IPC to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
B0002:11 Driver Frontal Stage 2 Deployment Control: Circuit Short to Ground When the RCM senses a short to ground on either driver air bag stage 2 circuit, a fault will be indicated.
B0002:12 Driver Frontal Stage 2 Deployment Control: Circuit Short to Battery When the RCM senses a short to voltage on either driver air bag stage 2 circuit, a fault will be indicated.
B0002:13 Driver Frontal Stage 2 Deployment Control: Circuit Open When the RCM measures greater than the desired resistance range between driver air bag stage 2 circuits, a fault will be indicated.
B0002:1A Driver Frontal Stage 2 Deployment Control: Circuit Resistance Below Threshold When the RCM measures less than the desired resistance range between driver air bag stage 2 circuits, a fault will be indicated.

 
PINPOINT TEST B: DTCs B0002:11, B0002:12, B0002:13 AND B0002:1A

 WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy and cause serious personal injury or death.

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

If a fault is detected, the RCM stores DTC B0005:11, B0005:12, B0005:13 or B0005:1A in memory and sends a message to the IPC to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
B0005:11 Collapsible Steering Column Deployment Control: Circuit Short to Ground A fault is indicated when the RCM senses a short to ground on either collapsible steering column circuit.
B0005:12 Collapsible Steering Column Deployment Control: Circuit Short to Battery A fault is indicated when the RCM senses a short to voltage on either collapsible steering column circuit.
B0005:13 Collapsible Steering Column Deployment Control: Circuit Open A fault is indicated when the RCM measures greater than the desired resistance range between the collapsible steering column circuits.
B0005:1A Collapsible Steering Column Deployment Control: Circuit Resistance Below Threshold A fault is indicated when the RCM measures less than the desired resistance range between the collapsible steering column circuits.

 
PINPOINT TEST C: DTCs B0005:11, B0005:12, B0005:13 AND B0005:1A

 WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy and cause serious personal injury or death.

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Only disconnect or reconnect SRS components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test D: DTCs B0010:11, B0010:12, B0010:13 and B0010:1A

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The RCM continuously monitors the passenger air bag module stage 1 and circuits for the following faults:

If a fault is detected, the RCM will store DTC B0010:11, B0010:12, B0010:13 or B0010:1A in memory and send a message to the IPC to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
B0010:11 Passenger Frontal Stage 1 Deployment Control: Circuit Short to Ground When the RCM senses a short to ground on either passenger air bag stage 1 circuit, a fault will be indicated.
B0010:12 Passenger Frontal Stage 1 Deployment Control: Circuit Short to Battery When the RCM senses a short to voltage on either passenger air bag stage 1 circuit, a fault will be indicated.
B0010:13 Passenger Frontal Stage 1 Deployment Control: Circuit Open When the RCM measures greater than the desired resistance range between passenger air bag stage 1 circuits, a fault will be indicated.
B0010:1A Passenger Frontal Stage 1 Deployment Control: Circuit Resistance Below Threshold When the RCM measures less than the desired resistance range between passenger air bag stage 1 circuits, a fault will be indicated.

 
PINPOINT TEST D: DTCs B0010:11, B0010:12, B0010:13 AND B0010:1A

 WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy and cause serious personal injury or death.

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

Pinpoint Test E: DTCs B0011:11, B0011:12, B0011:13 and B0011:1A

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The RCM continuously monitors the passenger air bag module stage 2 and circuits for the following faults:

If a fault is detected, the RCM will store DTC B0011:11, B0011:12, B0011:13 or B0011:1A in memory and send a message to the IPC to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
B0011:11 Passenger Frontal Stage 2 Deployment Control: Circuit Short to Ground When the RCM senses a short to ground on either passenger air bag stage 2 circuit, a fault will be indicated.
B0011:12 Passenger Frontal Stage 2 Deployment Control: Circuit Short to Battery When the RCM senses a short to voltage on either passenger air bag stage 2 circuit, a fault will be indicated.
B0011:13 Passenger Frontal Stage 2 Deployment Control: Circuit Open When the RCM measures greater than the desired resistance range between passenger air bag stage 2 circuits, a fault will be indicated.
B0011:1A Passenger Frontal Stage 2 Deployment Control: Circuit Resistance Below Threshold When the RCM measures less than the desired resistance range between passenger air bag stage 2 circuits, a fault will be indicated.

 
PINPOINT TEST E: DTCs B0011:11, B0011:12, B0011:13 AND B0011:1A

 WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy and cause serious personal injury or death.

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test F: DTCs B0020:11, B0020:12, B0020:13 and B0020:1A

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The RCM continuously monitors the driver seat side air bag module and circuits for the following faults:

If a fault is detected, the RCM stores DTC B0020:11, B0020:12, B0020:13 or B0020:1A in memory and send a message to the IPC to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
B0020:11 Left Side Airbag Deployment Control: Circuit Short to Ground When the RCM senses a short to ground on either driver seat side air bag circuit, a fault will be indicated.
B0020:12 Left Side Airbag Deployment Control: Circuit Short to Battery When the RCM senses a short to voltage on either driver seat side air bag circuit, a fault will be indicated.
B0020:13 Left Side Airbag Deployment Control: Circuit Open When the RCM measures greater than the desired resistance range between the driver seat side air bag circuits, a fault will be indicated.
B0020:1A Left Side Airbag Deployment Control: Circuit Resistance Below Threshold When the RCM measures less than the desired resistance range between the driver seat side air bag circuits, a fault will be indicated.

 
PINPOINT TEST F: DTCs B0020:11, B0020:12, B0020:13 AND B0020:1A

 WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy and cause serious personal injury or death.

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test G: DTCs B0021:11, B0021:12, B0021:13 and B0021:1A

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The RCM continuously monitors the LH Safety Canopy® and circuits for the following faults:

If a fault is detected, the RCM will store DTC B0021:11, B0021:12, B0021:13 or B0021:1A in memory and send a message to the IPC to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
B0021:11 Left Curtain Deployment Control 1: Circuit Short to Ground When the RCM senses a short to ground on either LH Safety Canopy® circuit, a fault will be indicated.
B0021:12 Left Curtain Deployment Control 1: Circuit Short to Battery When the RCM senses a short to voltage on either LH Safety Canopy® circuit, a fault will be indicated.
B0021:13 Left Curtain Deployment Control 1: Circuit Open When the RCM measures greater than the desired resistance range between the LH Safety Canopy® circuits, a fault will be indicated.
B0021:1A Left Curtain Deployment Control 1: Circuit Resistance Below Threshold When the RCM measures less than the desired resistance range between the LH Safety Canopy® circuits, a fault will be indicated.

 
PINPOINT TEST G: DTCs B0021:11, B0021:12, B0021:13 AND B0021:1A

 WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy and cause serious personal injury or death.

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test H: DTCs B0028:11, B0028:12, B0028:13 and B0028:1A

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The RCM continuously monitors the passenger seat side air bag module and circuits for the following faults:

If a fault is detected, the RCM will store DTC B0028:11, B0028:12, B0028:13 or B0028:1A in memory and send a message to the IPC to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
B0028:11 Right Side Airbag Deployment Control: Circuit Short to Ground When the RCM senses a short to ground on either passenger seat side air bag module circuit, a fault will be indicated.
B0028:12 Right Side Airbag Deployment Control: Circuit Short to Battery When the RCM senses a short to voltage on either passenger seat side air bag module circuit, a fault will be indicated.
B0028:13 Right Side Airbag Deployment Control: Circuit Open When the RCM measures greater than the desired resistance range between the passenger seat side air bag module circuits, a fault will be indicated.
B0028:1A Right Side Airbag Deployment Control: Circuit Resistance Below Threshold When the RCM measures less than the desired resistance range between the passenger seat side air bag module circuits, a fault will be indicated.

 
PINPOINT TEST H: DTCs B0028:11, B0028:12, B0028:13 AND B0028:1A

 WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy and cause serious personal injury or death.

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test N: DTCs B0082:11, B0082:12, B0082:13 and B0082:1A

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The RCM continuously monitors the passenger safety belt retractor load limiter and circuits for the following faults:

If a fault is detected, the RCM stores DTC B0082:11, B0082:12, B0082:13 or B0082:1A in memory and sends a message to the IPC to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
B0082:11 Passenger Seatbelt Load Limiter Deployment Control: Circuit Short to Ground When the RCM senses a short to ground on either passenger safety belt retractor load limiter circuit, a fault will be indicated.
B0082:12 Passenger Seatbelt Load Limiter Deployment Control: Short to Battery When the RCM senses a short to battery on either passenger safety belt retractor load limiter circuit, a fault will be indicated.
B0082:13 Passenger Seatbelt Load Limiter Deployment Control: Circuit Open When the RCM measures greater than the desired resistance range between the passenger safety belt retractor load limiter circuits, a fault will be indicated.
B0082:1A Passenger Seatbelt Load Limiter Deployment Control: Circuit Resistance Below Threshold When the RCM measures less than the desired resistance range between the passenger safety belt retractor load limiter circuits, a fault will be indicated.

 
PINPOINT TEST N: DTCs B0082:11, B0082:12, B0082:13 AND B0082:1A

 WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy and cause serious personal injury or death.

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test P: DTCs B0091:11, B0091:93, B0097:11 and B0097:93

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The RCM monitors the driver front door and RH C-pillar side impact sensors and circuits for the following faults:

If a fault is detected, the RCM will store DTC B0091:11, B0091:93, B0097:11 or B0097:93 in memory and send a message to the IPC to illuminate the air bag warning indicator.

The RCM communicates with each impact sensor, if the RCM is unable to communicate with the sensor, a DTC will be stored in memory. A CMDTC no operation (failure type: 93) can be set by a short to voltage on the return circuit of the impact sensor.

NOTE: A short to ground on either impact sensor feed circuit will set DTCs B0091:11 and B0097:11.

A short to voltage on either impact sensor feed circuit will set DTCs B0091:93 and B0097:93.



DTC Description Fault Trigger Condition
B0091:11 Left Side Restraints Sensor 1: Circuit Short to Ground When the RCM senses a shorted driver front door side impact sensor, a shorted RH C-pillar side impact sensor, a short to ground on the driver front door side impact sensor feed circuit or a short to ground on the RH C-pillar side impact sensor feed circuit, a fault will be indicated.
B0091:93 Left Side Restraints Sensor 1: No Operation When the RCM senses a faulted driver front door side impact sensor, a short to voltage on the feed or return circuit of the driver front door side impact sensor, a short to voltage on the feed or return circuit of RH C-pillar side impact sensor or an open feed or return circuit of the driver front door side impact sensor, a fault will be indicated.
B0097:11 Right Side Restraints Sensor 2: Circuit Short to Ground When the RCM senses a shorted driver front door side impact sensor, a shorted RH C-pillar side impact sensor, a short to ground on the driver front door side impact sensor feed circuit or a short to ground on the RH C-pillar side impact sensor feed circuit, a fault will be indicated.
B0097:93 Right Side Restraints Sensor 2: No Operation When the RCM senses a faulted RH C-pillar side impact sensor, a short to voltage on the feed or return circuit of RH C-pillar side impact sensor, a short to voltage on the feed or return circuit of the driver front door side impact sensor or an open feed or return circuit of the RH C-pillar side impact sensor, a fault will be indicated.

Pinpoint Test V: DTCs B1211:11, B1211:12, B1211:13 and B1211:1A

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The RCM continuously monitors the driver safety belt retractor pretensioner and circuits for the following faults:

If a fault is detected, the RCM stores DTC B1211:11, B1211:12, B1211:13 or B1211:1A in memory and sends a message to the IPC to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
B1211:11 Driver Seatbelt Retractor Pretensioner Deployment Control: Circuit Short to Ground When the RCM senses a short to ground on either driver safety belt retractor pretensioner circuit, a fault is indicated.
B1211:12 Driver Seatbelt Retractor Pretensioner Deployment Control: Short to Battery When the RCM senses a short to battery on either driver safety belt retractor pretensioner circuit, a fault is indicated.
B1211:13 Driver Seatbelt Retractor Pretensioner Deployment Control: Circuit Open When the RCM measures greater than the desired resistance range between the driver safety belt retractor pretensioner circuits, a fault is indicated.
B1211:1A Driver Seatbelt Retractor Pretensioner Deployment Control: Circuit Resistance Below Threshold When the RCM measures less than the desired resistance range between the driver safety belt retractor pretensioner circuits, a fault is indicated.

 
PINPOINT TEST V: DTCs B1211:11, B1211:12, B1211:13 AND B1211:1A

 WARNING: Never disassemble or tamper with seat belt deployable components, including pretensioners, load limiters and inflators. Never back probe deployable device electrical connectors. Tampering or back probing may cause an accidental deployment and result in personal injury or death.

 WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy and cause serious personal injury or death.

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test X: DTCs B1213:11, B1213:12, B1213:13 and B1213:1A

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The RCM continuously monitors passenger safety belt buckle pretensioner and circuits for the following faults:

If a fault is detected, the RCM stores DTC B1213:11, B1213:12, B1213:13 or B1213:1A in memory and sends a message to the IPC to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
B1213:11 Passenger Seatbelt Buckle Pretensioner Deployment Control: Circuit Short to Ground When the RCM senses a short to ground on either passenger safety belt buckle pretensioner circuit, a fault will be indicated.
B1213:12 Passenger Seatbelt Buckle Pretensioner Deployment Control: Short to Battery When the RCM senses a short to battery on either passenger safety belt buckle pretensioner circuit, a fault will be indicated.
B1213:13 Passenger Seatbelt Buckle Pretensioner Deployment Control: Circuit Open When the RCM measures greater than the desired resistance range between the passenger safety belt buckle pretensioner circuits, a fault will be indicated.
B1213:1A Passenger Seatbelt Buckle Pretensioner Deployment Control: Circuit Resistance Below Threshold When the RCM measures less than the desired resistance range between the passenger safety belt buckle pretensioner circuits, a fault will be indicated.

 
PINPOINT TEST X: DTCs B1213:11, B1213:12, B1213:13 and B1213:1A

 WARNING: Never disassemble or tamper with seat belt deployable components, including pretensioners, load limiters and inflators. Never back probe deployable device electrical connectors. Tampering or back probing may cause an accidental deployment and result in personal injury or death.

 WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy and cause serious personal injury or death.

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test Z: DTCs B13B7:11, B13B7:12, B13B7:13 and B13B7:1A

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The RCM continuously monitors second row right safety belt inflator and circuits for the following faults:

If a fault is detected, the RCM stores DTC B13B7:11, B13B7:12, B13B7:13 or B13B7:1A in memory and sends a message to the IPC to illuminate the air bag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:



DTC Description Fault Trigger Condition
B13B7:11 Second Row Right Inflatable Seatbelt Deployment Control: Circuit Short to Ground A fault is indicated when the RCM senses a short to ground on either second row right safety belt inflator circuit.
B13B7:12 Second Row Right Inflatable Seatbelt Deployment Control: Short to Battery A fault is indicated when the RCM senses a short to battery on either second row right safety belt inflator circuit.
B13B7:13 Second Row Right Inflatable Seatbelt Deployment Control: Circuit Open A fault is indicated when the RCM measures greater than the desired resistance range between the second row right safety belt inflator circuits.
B13B7:1A Second Row Right Inflatable Seatbelt Deployment Control: Circuit Resistance Below Threshold A fault is indicated when the RCM measures less than the desired resistance range between the second row right safety belt inflator circuits.

 
PINPOINT TEST Z: DTCs B13B7:11, B13B7:12, B13B7:13 and B13B7:1A

 WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy and cause serious personal injury or death.

 WARNING: Never disassemble or tamper with seat belt deployable components, including pretensioners, load limiters and inflators. Never back probe deployable device electrical connectors. Tampering or back probing may cause an accidental deployment and result in personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTICE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: SRS components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The RCM monitors all deployable device and sensor circuits for a signal cross coupled (short) fault between circuits. If the RCM detects a short between the circuits of one device and another device, it stores a DTC for each of the signal cross coupled faults in memory. The RCM sends a message to the IPC to illuminate the air bag warning indicator. Signal cross coupled diagnostics are not active when a normal loop fault is present (for example, if one loop is either shorted to battery/ground or has an open circuit or low resistance). Signal cross coupled diagnostics resume once the normal loop fault is repaired.

Normal Operation — OCSM

The OCSM continuously monitors the input voltage for correct operation. If the OCSM detects input voltage below 9.6 volts when another OCS fault is present, or if the OCSM detects voltage below 7.6 volts, regardless of fault status, it stores DTC U3003:16 in memory. If the OCSM detects input voltage above 16.5 volts when another OCS fault is present, or if the OCSM detects voltage above 18.5 volts, it stores DTC U3003:17 in memory. If the OCSM sets DTC U3003:16 or U3003:17, it sends a fault message to the RCM . The RCM then sends a message to the IPC to illuminate the air bag warning indicator.



DTC Description Fault Trigger Condition
U3003:16 Battery Voltage: Circuit Voltage Below Threshold If the RCM detects voltage below 9.5 volts with a SRS fault, it sets this DTC.
U3003:17 Battery Voltage: Circuit Voltage Above Threshold If the RCM detects voltage above 16 volts with a SRS fault or above 20 volts without a SRS fault, it sets this DTC.
U3003:16 Battery Voltage: Circuit Voltage Below Threshold If the OCSM detects voltage below 9.6 volts when another OCS fault is present, or if the OCSM detects voltage below 7.6 volts, regardless of fault status.
U3003:17 Battery Voltage: Circuit Voltage Above Threshold If the OCSM detects voltage above 16.5 volts when another OCS fault is present, or if the OCSM detects voltage above 18.5 volts, regardless of fault status.

Pinpoint Test AE: DTCs B0061:11, B0061:12, B0061:13 and B0061:1C

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The BTS operates in conjunction with the OCS . The OCS interprets a variable voltage signal provided by the BTS to identify the possible presence of a child safety seat in the front passenger seat. The voltage output of the BTS is proportional to the amount of tension applied to the sensor by the belt. No tension outputs a low voltage (approximately 0.95 volt), and high tension outputs a high voltage (approximately 3.8 volts), in relation to the reference voltage.

The OCSM monitors the BTS and related circuits for the following faults:

If a fault is detected, the OCSM stores DTC B0061:11, B0061:12, B0061:13 or B0061:1C in memory and sends a message to the RCM , which stores DTC B00A0:09 or B00A0:68 in memory and sends a message to the IPC to illuminate the air bag warning indicator.



DTC Description Fault Trigger Condition
B0061:11 Passenger Seatbelt Tension Sensor: Circuit Short to Ground A fault is indicated if the BTS VREF circuit is open or if the BTS signal circuit is shorted to ground. An internally-shorted BTS can also set this DTC.

This DTC is detected by calculating the ratio of the measured BTS signal divided by the BTS VREF value. If the ratio equals less than .1, this DTC sets.
B0061:12 Passenger Seatbelt Tension Sensor: Circuit Short to Battery A fault is indicated when the BTS signal circuit is shorted to battery voltage or BTS VREF. An open BTS return circuit also sets this DTC.

This DTC is detected by calculating the ratio of the measured BTS signal divided by the BTS VREF value. If the ratio equals greater than .9, this DTC sets.
B0061:13 Passenger Seatbelt Tension Sensor: Circuit Open A fault is indicated when the OCSM measures resistance above a calibrated threshold on the BTS signal circuit.
B0061:1C Passenger Seatbelt Tension Sensor: Circuit Voltage Out of Range A fault is indicated when the OCSM measures greater than 2.0 volts on the BTS signal circuit while the passenger safety belt is not buckled.

Pinpoint Test AO: DTCs U200E:11, U200E:12 and U200E:1A

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.

Normal Operation

The OCSM monitors the BTS VREF circuit for faults. If the OCSM detects a fault, it stores DTC U200E:11, U200E:12 or U200E:1A in memory and sends a message to the RCM . The RCM stores DTC B00A0:09 memory and sends a message to the IPC to illuminate the air bag warning indicator.

 
PINPOINT TEST AO: DTCs U200E:11, U200E:12 AND U200E:1A

 WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.

NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .

NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
