Normal Operation
The lighting control module (LCM) monitors the luggage compartment lid anti-theft inhibit switch status. The luggage compartment lid anti-theft inhibit switch grounds circuit 1350 (WH/PK) on circuit 57 (BK) when the luggage compartment lid lock cylinder is turned to open with the key. The LCM receives this ground signal and inhibits the alarm from activating from the luggage compartment lid. When the luggage compartment lid is closed the luggage compartment lid is again monitored by the LCM.

Possible Causes
- circuit 57 (BK) open
- circuit 1350 (WH/PK) open or short to ground
- luggage compartment anti-theft alarm inhibit switch
- LCM
