Body Control Module (BCM): Installation

NOTE: If installing a new BCM, the ignition cannot be turned on until 2 keys are programmed to the vehicle. The BCM still communicates with the diagnostic scan tool with the ignition off. If necessary, use the previous diagnostic scan tool session or start a diagnostic scan tool session using the PCM part number or tear tag number located on the PCM.

NOTE: If installing a new BCM, verify at least 2 of the vehicle keys are available prior to carrying out this procedure.

To install, reverse the removal procedure.

NOTE: Carry out the remaining steps only if installing a new BCM.
NOTE: A diagnostic scan tool should not be used to program keys for this specific step.

Program the keys.
- Place the first key in the backup starting location. Refer to: Passive Anti-Theft System (PATS) - Component Location .
- Press the START/STOP button and wait approximately 6 seconds.
- Press the START/STOP button and remove the first key.
- Place the second key in the backup starting location.
- Press the START/STOP button.
Carry out the parameter reset. Refer to: Anti-Theft Key Programming - Scan Tool .
Using a diagnostic scan tool, complete the PMI process for the BCM following the on-screen instructions.
Using a diagnostic scan tool, carry out the battery monitor sensor reset following the on-screen instructions (Toolbox > Body > BMS Reset).
Configure the customer preference programmable parameters. Refer to: Module Programming .
Train the tire pressure sensors. Refer to: Tire Pressure Monitoring System (TPMS) Sensor Location Calibration .
Carry out the BCM self-test (must include an on-demand self-test) and then repeat the self-test to confirm all Diagnostic Trouble Codes (DTCs) have been cleared.
