Trunk / Liftgate Switch: Description and Operation
Exterior Handle Switch - Operation
OPERATION
When the exterior liftgate handle is pulled, a mechanical cable inside the liftgate activates the power liftgate release switch in the power liftgate latch
assembly. A hard-wired signal is then detected by the Power Liftgate Control Module. The power liftgate control module then looks at the vehicle lock
status on the Controller Area Network (CAN) data bus. If the vehicle is not locked and the operating conditions are met, the power liftgate control
module then applies power to the latch mounted motor, which moves the liftgate from the primary closed and latched position to the open and movable
position.
If the liftgate is not pulled open within seven seconds, once the latch releases, the latch will automatically cinch closed.
