Pinpoint Test P: The RKE Transmitter Has Poor Range Performance

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.

Normal Operation and Fault Conditions

The RKE transmitter has a normal operating range of 20 m (66 ft). The TPM module has an internal antenna to receive the RKE transmitter signal.

Possible Sources

IA key
IA key battery
Aftermarket system
High power devices
TV/radio transmission towers
TPM module

Visual Inspection and Diagnostic Pre-checks

Inspect the IA key for damage.
Inspect the IA key battery.
Inspect for aftermarket RKE systems.

PINPOINT TEST P: THE RKE TRANSMITTER HAS POOR RANGE PERFORMANCE

NOTE: A least 2 programmed IA keys must be present to begin diagnosis of the RKE system.

Test Step	Result / Action to Take
P1 CHECK FOR THE CORRECT RKE TRANSMITTERS
Check that the correct IA keys are used with the vehicle. Compare the IA keys with the one shown in Component Description - Intelligent Access (IA) Key in Handles, Locks, Latches and Entry Systems . Are all the correct RKE transmitters present?	Yes GO to P2 . No The system cannot be tested without the correct RKE transmitters. INFORM the customer that the correct RKE transmitters must be present to proceed with diagnosis of the system.
P2 CHECK ALL THE RKE TRANSMITTERS FOR POOR RANGE PERFORMANCE
NOTE: The 20 m (66 ft) measurement of range is not the standard but is a guideline that clearly indicates a vehicle is experiencing normal range performance. Check all the RKE transmitters for poor range performance (less than 20 m [66 ft]). Do all the RKE transmitters experience poor range?	Yes GO to P4 . No GO to P3 .
P3 CHECK THE IA KEY BATTERY
Using a thin coin, open the battery cover of the suspect IA key. Do not clean off any grease from the battery terminals on the back surface of the circuit board. Verify the correct battery is used (CR2032). Remove the IA key battery and measure the voltage. Is the voltage greater than 2.5 volts?	Yes REPLACE the suspect IA key. PROGRAM the new IA key. REFER to Key Programming Using Diagnostic Equipment in Section 419-01C . INFORM the customer that any IA keys not present need to be programmed. No INSTALL a new battery (make sure the battery seats correctly). DO NOT reprogram the IA key (weak or dead batteries do not erase IA keys from memory).
P4 CHECK THE LOCATION OF THE VEHICLE AND THE APPROACH ANGLES AROUND THE VEHICLE
NOTE: The RKE transmitter range performance may be degraded in certain locations. For example, if the vehicle is within 0.8 km (0.5 miles) of high-power devices or radio/TV towers, the operating distance of the RKE transmitters may be reduced. Make sure the poor performance is consistent in nature and is not from one approaching angle. Is the poor range performance consistent around the vehicle?	Yes GO to P5 . No The system is operating correctly at this time. The range may have been affected by environmental interference.
P5 CHECK FOR CORRECT TPM MODULE OPERATION
Disconnect and inspect the TPM module connector. Repair: corrosion (install new connector or terminals – clean module pins) damaged or bent pins – install new terminals/pins pushed-out pins – install new pins as necessary Reconnect the TPM module connectors. Make it seats and latches correctly. Operate the system and determine if the concern is still present. Is the concern still present?	Yes CHECK On-Line Automotive Service Information System (OASIS) for any applicable TSBs . If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new TPM Module. REFER to Section 204-04 . No The system is operating correctly at this time. The concern may have been caused by module connections.

Pinpoint Test S: DTCs B106E, B106F

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.

Normal Operation and Fault Conditions

The DDM controls the output of several vehicle systems by means of solid state drivers. A DTC sets when an overload occurs on any of these drivers. The module also tracks the number of repetitive faults on each of these circuits, and then it compares that said number of overloads to 3 progressive thresholds established for each circuit. If the third threshold has not been met, the DTC for the affected circuit can be cleared by eliminating the fault, clearing the DTCs and then running a self-test.

At the point that each of the first 2 thresholds is met, DTC B106E sets along with a DTC related to the affected circuit. Once the final (third) threshold has been met, the affected output is permanently disabled, and DTC B106F sets, at which time the DDM must be replaced.

DDM DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Conditions
B106E	Solid State Driver Disabled Due to Short Circuit	Sets when the DDM has disabled an output circuit due to a repetitive fault that overloads said circuit. A corresponding DTC for the circuit in question is also set.
B106F	Module Disabled Due to External Fault	Sets when the DDM has permanently disabled one or more output functions due to a repetitive circuit overload. DTC B1342 also sets at this time.

When DTC B1342 is set because the module has reached a third threshold and the DDM has permanently disabled an output, no DTCs can be cleared from the DDM . Using the module self-test to confirm a repair is not possible and a measurement using a digital multimeter of the affected output circuit is required to make sure the fault condition no longer exists.

Possible Sources

DDM output circuit
DDM

PINPOINT TEST S: DTCs B106E, B106F

Test Step	Result / Action to Take
S1 REVIEW THE DTCs
NOTICE: First follow the necessary diagnostics to resolve DTC B106E and any other present DTCs (ignoring B106F). DTC B106E is only present when there is another DTC due to software or circuitry issues that must be resolved before another self-test is run. DTC B106F is only present once the final threshold has been met. Failure to correct the fault condition first may cause damage to the new DDM , resulting in a repeat repair. Review the DTCs from the DDM self-test. Are any other DTCs present, besides B106E, B106F or B1342?	Yes CORRECT the DTCs. REFER to Driver Door Module (DDM) DTC Chart in this section. After the repair, GO to S2 . No GO to S2 .
S2 REPEAT THE DDM SELF-TEST
Ignition ON. Using a scan tool, clear the DTCs and repeat the DDM self-test. Is DTC B106F or DTC B1342 present?	Yes INSTALL a new DDM . REFER to Driver Door Module (DDM) . No The system is operating correctly at this time. The circuit short has been repaired.
