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.
Diagnostic Aids
When Gray wire from BCM to decklid/liftgate release solenoid is shorted to ground and BCM attempts to switch battery voltage, high current flow will result. BCM goes into protective mode and will not allow reactivation for as long as 3 minutes. If problem is intermittent, check wiring harness and connectors for damage, backed out terminals and loose connection. Check for broken or chafed wire insulation. Perform wiggle test to aid in diagnosing intermittents.
