Circuit Description
WARNING: This page is about a different car, the 2006 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
The body control module (BCM) stores the last 4 digits of the sensing and diagnostic module (SDM) part number, information also called restraints ID. After the BCM is reprogrammed the restraints ID is set to zero. A restraints ID relearn must be performed for the BCM. For more information on this procedure refer to Body Control Module (BCM) Programming/RPO Configuration .
