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. When the luggage compartment lid is opened, the luggage compartment lid ajar switch closes and signals the trunk pull-down module through circuit 486 (BN/WH). The trunk pull-down module 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).

DTC B1334 - sets when the LCM senses a short to ground on the trunk ajar signal, circuit 700 (WH/VT).

Possible Causes
- Circuit 486 (BN/WH) short to ground
- Circuit 700 (WH/VT) short to ground
- Circuit 707 (WH/YE) short to ground
- Luggage compartment lid release solenoid/ajar switch
- Trunk pull-down module
- LCM
