Body Control Module
CAUTION:
When Body Control Module (BCM) is replaced, new BCM will automatically program to resistance of ignition key or interrogator setting that is used for first time ignition switch is turned to RUN position. This process can only be performed once BCM is replaced.
NOTE:
Replacement Body Control Module (BCM) will be programmed by manufacturer in a factory test mode. This mode allows only limited functionality. To exit factory test mode, cycle ignition switch between RUN and OFF positions 10 times.
After a replacement Body Control Module (BCM) has been installed, use one of customer's keys to turn ignition switch to RUN position. Start engine to verify system operation. If SECURITY warning indicator comes on for about 5 seconds and then goes out, BCM is programmed properly. If SECURITY warning indicator flashes (about one flash per second) until ignition switch is turned to OFF position, BCM did not program. Check for faulty system components and wiring of theft deterrent system. See ANTI-THEFT SYSTEMS - CAMARO & FIREBIRD article.
