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 needs to be performed for the BCM. For more information on this procedure, refer to Body Control Module Programming and Setup .
