Body Control Module (BCM) Replacement
WARNING: This page is about a different car, the 2005 GMC Sierra, 2005 GMC Cab & Chassis Sierra, 2005 Chevrolet Silverado, and 2005 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 in Computer/Integrating Systems.
- Theft Learn-Refer to Programming Theft Deterrent System Components in Theft Deterrent. 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.
