Body Control Module Programming and Setup: Notes
The body control module (BCM) must be programmed with the proper calibration software. The BCM stores and utilizes this information however if it is not properly configured with the correct calibration software, the BCM will not control all of the vehicle features properly.
Ensure that the following conditions exist in order to prepare for BCM programming:
- The battery is fully charged.
- The MDI data link connectors are secure.
- The scan tool is loaded with the most current software version.
- All disconnected control modules and devices are reconnected securely.
- This entire procedure has been reviewed before proceeding.
Do not reprogram the body control module unless directed by a service procedure or a service bulletin.
