Normal Operation
The generic electronic module (GEM) grounds the control side of the battery saver relay located in the central junction box (CJB). When the relay is energized, voltage is supplied to the cargo lamp through circuits 29-LC7 (OG/BU) and 29-LB6 (OG/YE). The ajar switch controls the ground side of the cargo lamp on circuits 31S-LB6 (BK/YE) and 31S-LB1 (BK/BU) to illuminate the cargo lamp.

Possible Causes
- Circuit 29-LB6 (OG/YE) open
- Circuit 31S-LB6 (BK/YE) open
- Circuit 31S-LB1 (BK/BU) open
- Circuit 31-GL20 (BK) open
- Liftgate latch
- Cargo lamp
