Luggage Compartment Description and Operation General
The rear compartment release system consists of the following components:
| • | Rear compartment lid release switch |
| • | Rear compartment lid release actuator |
| • | Instrument panel cluster (IPC) |
| • | Rear integration module (RIM) |
| • | Drivers door module (DDM) |
When the trunk release switch is pressed, the release switch grounds a switch input to the driver's window switch. The driver's window switch sends a signal to the drivers door module by a simple bus interface. The drivers door module sends a class 2 message to the rear integration module which grounds the control circuit of the trunk release relay in the rear fuse block for 1/2 second.
The trunk release relay is hot at all times through a 15 A fuse. When the trunk release relay is energized, the trunk release relay sends battery voltage to the trunk release actuator.
Luggage Compartment Description and Operation Ajar Indicator
TRUNK AJAR -- 24
The IPC illuminates the TRUNK AJAR -- 24 indicator in the DIC when
the rear integration module (RIM) detects that the trunk is ajar or open (signal
circuit is low). The IPC receives a class 2 message from the RIM requesting
illumination. The IPC sends a class 2 message to the radio in order
to activate an audible warning.
