Intermittent DTC C1963 In Anti-Lock Brake Module (10-21-14)

INTERMITTENT DTC C1963 IN ANTI-LOCK BRAKE MODULE

TECHNICAL SERVICE BULLETIN

ISSUE

Some 2010 Edge/MKX vehicles may exhibit an intermittent C1963 diagnostic trouble code (DTC) with no other DTCs present in the anti-lock brake module (ABS), powertrain control (PCM), or steering angle sensor module (SASM). The customer may observe an intermittent stability control system/traction control light illumination.

ACTION

Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

If other DTCs are present with the C1963 in the ABS module, the SASM module, or PCM do not continue with this article. Refer to WSM or PC/ED for normal diagnostics. The C1963 DTC can be set due to other issues with the SASM, the stability control sensor cluster, the PCM, and the wheel speed sensors.

1. Using IDS, monitor the steering wheel angle position PID (SWA POS) from the SASM. Ensure the PID readings follow as the steering wheel is slowly rotated clockwise and counterclockwise the PID will change in 1 degree increments when the steering wheel is rotated very slowly). If the PID does not follow the steering wheel movements, do not continue with this article. Refer to WSM, Section 206-09 for normal diagnostics.
2. Inspect the stability control sensor cluster to ensure it is properly fastened to the vehicle and that all electrical connections are fully seated.
3. Update the ABS module software by reprogramming the module using IDS release 69.04.
