Body Control Module (BCM) Replacement

If the BCM is replaced, the following procedures must be performed in the subsequent order:

    • BCM Reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems for replacement, setup, and programming.
    • Brake Pedal Position Sensor Calibration--Refer to Brake Pedal Position Sensor Calibration in Lighting Systems.

Sensing and Diagnostic Module (SDM) Replacement

If the sensing and diagnostic module (SDM) is replaced, the following procedure must be performed:

Setup SDM Part Number in BCM. Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems for the proper procedure.

Brake Apply Sensor (BAS) Replacement

If the brake apply sensor (BAS) is replaced, the following procedures must be performed:

    • BCM Reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems for replacement, setup, and programming.
    • Brake Pedal Position Sensor Calibration--Refer to Brake Pedal Position Sensor Calibration in Lighting Systems.

Body Control Module (BCM) Reprogramming

If the BCM is reprogrammed, the following procedures must be performed:

    • BCM Reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems for replacement, setup, and programming.
    • Brake Pedal Position Sensor Calibration--Refer to Brake Pedal Position Sensor Calibration in Lighting Systems.
