Body Control Module (BCM) Programming/RPO Configuration: Notes

WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.

A new body control module (BCM) must be programmed with the proper 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 possible RPO's available for the vehicle. Ensure that the following conditions exist and are met in order to prepare for BCM programming:

Understand this entire procedure.
The battery is fully charged.
The ignition switch is in the ON position.
The data link connector (DLC) is accessible.
All disconnected modules and devices are reconnected before programming.
Follow all Scan Tool on screen directions.
Take time to verify the VIN on the Scan Tool is correct, failure to do this could result in the service part being made unprogrammable.
