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
The liftgate module supplies power and ground to the liftgate clutch, which is part of the liftgate motor assembly. Upon receiving a liftgate open request, the liftgate module supplies voltage to the clutch via the liftgate motor engage control circuit. The liftgate motor disengage control circuit supplies a ground. With the clutch energized, the motor output is mechanically connected to the liftgate and power liftgate operation is allowed. The liftgate motor clutch engages or disengages the liftgate motor to the liftgate drive gear and is the component that determines power or manual operation.
