Body Control Module
Ensure all components related to the repair are properly connected. If Body Control Module (BCM) was replaced, you must enable Vehicle Theft Security System (VTSS) if equipped by using the key to unlock the liftgate while hood is open. If BCM was replaced you must program other options as necessary by using scan tool. To enable automatic headlight operation, vehicle must be driven over 3 miles and BCM must see one key transmission from remote keyless entry transmitter.
