Rear Compartment Lid (trunk) release actuation is controlled
by the following components.
• | Rear Compartment Lid Release Relay |
• | Instrument Panel Module (IPM) |
• | Rear Integration Module (RIM) |
• | Rear Compartment Lid Release Switch |
• | Rear Compartment Lid Release Actuator |
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 ground circuit for
the battery voltage from the ALDL fuse, the trunk release relay is 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.
