Test H: The Luggage Compartment Lamps Are Inoperative

PINPOINT TEST H: THE LUGGAGE COMPARTMENT LAMPS ARE INOPERATIVE

Normal Operation
The luggage compartment lamps are controlled by the lighting control module (LCM). The LCM receives a signal from the luggage compartment lid ajar switch through the trunk pull-down module, or the luggage/trunk module (LTM) if equipped with a power luggage compartment lid. When the luggage compartment lid is opened, the luggage compartment lid ajar switch closes and signals the trunk pull-down module, or the LTM through circuit 486 (BN/WH). The trunk pull-down module, or the LTM signals the LCM through circuit 700 (WH/VT) to request luggage lamp operation. The luggage lamps are supplied voltage through circuit 705 (LG/OG). The LCM controls the ground side of the luggage compartment lamps through circuit 707 (WH/YE).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Luggage lamp assembly
- Trunk pull-down module
- Luggage compartment lid release solenoid/ajar switch
- LTM
- LCM
