Rear Exterior Liftgate Release Switch

WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

The rear exterior liftgate release switch is a momentary contact switch that routes the voltage signal to ground when pressed. The signal is sent from the BCM and the RGTM.

If the doors were not previously electronically unlocked when the rear exterior liftgate release switch is pressed, the BCM activates the liftgate passive entry feature. If the BCM detects a valid programmed passive key, the BCM sends a message to the RGTM to open the liftgate. If no passive key is detected, the request is ignored.

If the doors were previously electronically unlocked when the liftgate switch is pressed, the RGTM opens the liftgate. The RGTM receives the door lock/unlock status from the BCM over the CAN.

Any subsequent presses of the switch stops the motion or reverses direction.
