WARNING: This page is about a different car, the 2019 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
When the liftgate release switch is pressed, the BCM sends a message to the RGTM, which opens or stops the motion of the liftgate. The doors must be electronically unlocked before the BCM sends the message to the RGTM.
Any subsequent presses of the switch stops the motion or reverses direction.
