Body Control Module (BCM) Replacement

If the body control module (BCM) is replaced, the following procedures must be performed in the following order:

1. BCM reprogramming - Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems.
2. 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.
