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.
Circuit/System Description
When the rear access panel release switch is pressed, the voltage level within the rear access panel signal circuit drops, the body control module (BCM) will detect the voltage drop and in turn will then send a serial data message to the instrument panel cluster (IPC). If the vehicle speed is less than 3 km/h (1 mph) the IPC will energize the door lock relay causing the switch side of the relay to close and provide a ground for the rear access panel actuators.
