The liftgate can be released by operating the liftgate release switch or pressing the liftgate release button on the key fob. The gear selector may be in any position, but vehicle speed must equal 0 for the liftgate to release.

Pressing the liftgate release switch closes a contact providing a ground for the liftgate release switch signal circuit. The body control module (BCM) will detect the voltage drop and command voltage to be supplied to the liftgate release relay control circuit thus energizing the LIFTGATE RELEASE relay which provides voltage to the release actuator releasing the liftgate.
