Normal Operation
The luggage compartment lid module receives voltage from the central junction box (CJB) through circuits 640 (RD/YE) and 1524 (DB). The luggage compartment lid module is grounded through circuits 57 (BK) and 676 (PK/OG). The luggage compartment lid latch release module supplies voltage to the luggage compartment release solenoid through circuit 605 (RD). The luggage compartment lid module monitors the ajar switch.

The module has a vehicle speed output (VSO) signal that is used to shut down the system if there is a vehicle speed of approximately 5 kph (3 mph) or more. For diagnostics, the module uses the International Standards Organization (ISO) network. Whenever battery voltage is lost to the luggage compartment lid module, luggage compartment lid motor, or the luggage compartment lid closing motor, the system must be initialized.

Possible Causes
- fuse(s)
- circuit 57 (BK) open
- circuit 605 (RD) open or short to ground
- circuit 679 (GY/BK) open or short to ground
- circuit 1524 (DB) open or short to ground
- luggage compartment lid latch
- luggage compartment lid module
- message center module
- powertrain control module (PCM)
- navigation system module
