Body Control Module (BCM) Replacement
WARNING: This page is about a different car, the 2006 GMC Sierra, 2006 GMC Cab & Chassis Sierra, 2006 Chevrolet Silverado, and 2006 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
If the body control module (BCM) is replaced, the following procedures must be performed in the following order:
- BCM Reprogramming-Refer to Body Control Module (BCM) Programming/RPO Configuration .
- Theft Learn-Refer to Programming Theft Deterrent System Components . A new BCM will learn the Passlock(tm) information automatically but the powertrain control module (PCM) must still learn the theft information from the BCM.
