Programming the Body Control Module

1998 Pontiac Firebird V8-5.7L VIN GSECTION Programming the Body Control Module
The body control module (BCM) is capable of accepting vehicle access code (VAC) programming from any four remote control door lock transmitters. Up to four remote control door lock transmitters can be programmed. When four transmitters are programmed, they must be programmed one after the other, during the same program sequence. Transmitters may not be programmed simultaneously. Each transmitter is manufactured with a permanent VAC combination (one of over 4 billion combinations). The code cannot be changed for the life of the transmitter. The BCM can only be programmed by the transmitters while in the program mode.
