Body Control Module (BCM) Programming/RPO Configuration: Notes
A new body control module (BCM) must be programmed with the proper regular production option (RPO) configurations. The BCM stores the information regarding the vehicle options and if the BCM is not properly configured with the correct RPO codes the BCM will not control all of the features properly. The Tech 2 software will automatically prompt you with the various RPO's available for the vehicle. Ensure that the following conditions exist in order to prepare for BCM programming:
- This entire procedure has been reviewed before starting
- The battery is fully charged.
- A CANdi module is installed between the vehicle and the scan tool.
- The ignition switch is in the ON position.
- The data link connector (DLC) is accessible.
- All disconnected modules and devices are reconnected before programming.
