Rear Hatch/Gate Description and Operation

The rear hatch can be released by placing the transaxle in park, unlocking all the doors and then pressing the touchpad located at the rear of the vehicle above the number plate.

Pressing the touchpad closes a contact providing a ground for the rear closure handle switch open signal circuit. The body control module (BCM) will detect the voltage drop and will pulse 12 V to one side of the relay coil and provide a ground for the other side of the relay coil, this will briefly energise the tailgate relay closing the switch contacts and provide B+ voltage to the tailgate latch. When the doors are locked, the BCM will disable the rear hatch release system by ignoring the tailgate release switch input command and not providing 12 V for the tailgate relay.
