OPERATION
When the exterior handle switch is depressed, with the liftgate in the closed position, a message is sent to the Body Control Module (BCM). The BCM then sends a signal to the power liftgate control module via the Programmable Communication Interface (PCI) data bus circuit. The power liftgate control module then sends a signal to the power latch mounted actuator, which moves the liftgate from the primary closed and latched position to the open and movable position. If the liftgate is not pulled open once the latch releases within a few seconds, the latch will cinch closed again.
