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 interior lamps through circuit 29-LC7 (OG/BU). The GEM monitors the door ajar switch status on circuits 31S-GL9 (BK/YE) (LH front), 31S-GL12 (BK/OG) (LH rear), 31S-GL16 (BK/BU) (RH front) and 31S-GL19 (BK/GN) (RH rear). The door ajar switches are normally open when the doors are closed. When the GEM determines a door is open, the GEM then controls the ground side of the interior lamp on circuit 31S-LC7 (BK/BU) to illuminate the interior lamp.
