    Symptom Chart — NVH

    NOTE: NVH symptoms should be identified using the diagnostic tools that are available. For a list of these tools, an explanation of their uses and a glossary of common terms, refer to Section 100-04 . Since it is possible any one of multiple systems may be the cause of a symptom, it may be necessary to use a process of elimination type of diagnostic approach to pinpoint the responsible system. If this is not the causal system for the symptom, refer back to Section 100-04 for the next likely system and continue diagnosis.

    Condition Possible Sources Action
    • An exterior mirror vibrates/loose
    • Exterior mirror mounting nuts and bolt loose
    • TIGHTEN nuts and bolts to 9 Nm (80 lb-in).
      • Exterior mirror glass is loose

            Pinpoint Tests

             

            Pinpoint Test A: Both Non-Memory Mirrors Are Inoperative

            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 124 , Power Mirrors for schematic and connector information.

            Normal Operation and Fault Conditions

            The accessory delay relay is located inside the BCM and supplies voltage to the master window control switch when the BCM energizes the relay by grounding the relay coil. The exterior mirror control switch is integral to the master window control switch and receives power whenever the master window control switch is powered by the accessory delay relay. The exterior mirror control switch has only one ground circuit. The exterior mirrors share a common circuit for both up/down and right/left movement.

            Pinpoint Test E: The Memory Mirror is Inoperative

            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 124 , Power Mirrors for schematic and connector information.

            Normal Operation and Fault Conditions

            The exterior mirror control switch sends voltage and ground inputs to the Driver Door Module (DDM) which controls LH mirror movement by providing the appropriate voltage and ground polarity to the LH exterior mirror up/down and left/right motors. The Driver Seat Module (DSM) controls RH mirror movement by providing the appropriate voltage and ground polarity to the RH exterior mirror up/down and left/right motors. The LH and RH exterior mirrors each contain potentiometers for up/down and left/right position status. The DDM (LH mirror) and DSM (RH mirror) supply the exterior mirror feedback potentiometers a reference voltage and reference ground. The DDM and DSM use these feedback signals to store/recall mirror positions.



             DTC Fault Trigger Conditions

            DTC Description Fault Trigger Conditions
            • B1667
            		Mirror Driver Up/Down Motor Stalled During self-test, the DDM (LH mirror) or DSM (RH mirror) attempts to operate the exterior mirror motor and uses the motor's position sensor to monitor movement. If no motor movement is sensed, the DDM or DSM disables the output after 250 milliseconds and the DTC is set. The DDM or DSM will retry motor operation on the next activation of the exterior mirror control switch.
            • B1669
            		Mirror Passenger Up/Down Motor Stalled
            • B1668
            		Mirror Driver Right/Left Motor Stalled During self-test, the DDM (LH mirror) or DSM (RH mirror) attempts to operate the exterior mirror motor and uses the motor's position sensor to monitor movement. If no motor movement is sensed, the DDM or DSM disables the output after 250 milliseconds and the DTC is set. The DDM or DSM will retry motor operation on the next activation of the exterior mirror control switch.
