Rear Compartment Lid Release Operation

When the exterior rear compartment lid release switch is pressed, the trunk release switch signal circuit is switched to ground. The BCM responds by applying battery voltage to the trunk release relay control circuit which energizes the rear compartment lid release relay. The rear compartment lid release relay is supplied with battery voltage at all times from an instrument panel fuse. With the relay coil energized, the relay switch contacts close allowing battery voltage to flow to the rear compartment lid release actuator causing the rear compartment lid to release. The exterior rear compartment lid release switch is permanently grounded to a fixed body ground.

When accessing the rear compartment using the key fob, a valid keyless entry transmitter is required to be within a 30 meter range of the vehicle. This allows the required keyless access communications to occur between the rear compartment antenna and the keyless entry transmitter. For more information about keyless access, refer to Keyless Entry System Description and Operation.
