Luggage Compartment Description and Operation General

Rear Compartment Lid (trunk) release actuation is controlled by the following components.

Battery voltage for the coil side of the trunk release relay is supplied through the Valet switch (with the valet switch in the OFF position) by the ALDL fuse located in the Underhood Fuse (Bussed) Block. Battery voltage for the switch side of the trunk release relay is supplied by the Body fuse located in the Rear Fuse (Bussed) Block. When the rear compartment lid release switch is momentarily pressed, it provides a ground circuit for the trunk release signal of the Instrument Panel Module (IPM). When the IPM senses that the switch has been activated, it sends a Serial Data Class 2 message to the Rear Integration Module (RIM). The RIM then provides a path to ground on the F/TNK DR REL relay control circuit. The trunk release relay is then energized, and battery voltage is applied through the switch side contacts of the trunk release relay to the rear compartment lid release actuator. The actuator is connected to ground through a ground splice pack located at the left rear corner of the rear compartment, near the left tail lamp connector.

Luggage Compartment Description and Operation Trunk Ajar Indicator

The IPC illuminates the TRUNK OPEN indicator in the DIC when the rear integration module (RIM) detects that the rear compartment is open and the ignition is ON. The IPC receives a class 2 message from the RIM requesting illumination.
