Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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.
