Power Liftgate Latch

WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.

The power liftgate latch is responsible for latching, unlatching, and cinching the liftgate. The power liftgate latch contains the unlatch/cinching motor, detent switch, forkbolt primary and secondary switches, and the sector gear switches.

Power Liftgate Detent Switch and Forkbolt Primary and Secondary Switches

The power liftgate detent switch and forkbolt primary and secondary switches provide inputs to the LTM to determine liftgate latch position. The liftgate is in the primary position when the liftgate is in the full closed position. The liftgate is in the unlatch position when the liftgate is open and completely out of the striker. The LTM receives inputs from the power liftgate detent switch, forkbolt primary and secondary switches in the following manner:
