Liftgate Release

The liftgate release system is inhibited when the vehicle speed exceeds 7 km/h (4.3 mph). The liftgate release system is also inhibited from the release switch when the vehicle doors are locked.

When the liftgate release system is not inhibited, the liftgate latch can be released from the liftgate release switch.

The BCM sends a voltage signal to the liftgate release switch. When the liftgate release switch is pressed, the signal is routed to ground, pulling the signal low and indicating a request to release the liftgate latch.

When the BCM receives a valid request to release the liftgate latch, the BCM provides ground to an integrated relay in the BJB, which supplies voltage to the latch. The liftgate latch then actuates to release the liftgate.
