Dome Lamp: Description and Operation

DOME FLUORESCENT WORK LAMPS

DOME FLUORESCENT WORK LAMPS COMPONENTS
The dome fluorescent work lamps system consists of the following components:
- The body control module (BCM) - Class 2 module that requires programming when replaced
- The AUXILIARY 1 Fuse 32 50A - Located in the body fuse block and is hot at all times
- The DOME FLUORESCENT WORK LAMPS fuse 2 10A fuse - Located in the rear fuse block and is hot at all times
- The Dome Fluorescent Work Lamp Relay - Located below the rear fuse block
- The dome fluorescent work lamps - With on/off switches integrated into each lamp assembly
DOME FLUORESCENT WORK LAMPS CONTROLS
Each dome fluorescent work lamps is equipped with an integral ON/OFF switch. The work lamps will remain on until manually turned off as long as the key is in the RUN position. The work lamps will also remain on for approximately 10 minutes after the ignition key has been turned to the OFF or ACCY positions. If the work lamp is turned ON with the ignition switch either in the OFF or ACCY positions, within 2 minutes after a 10 minute time out, the work lamp will turn on and remain on until the battery fully discharges.

DOME FLUORESCENT WORK LAMPS OPERATION
Voltage is supplied to the relay switch and coil side from the dome fluorescent work lamp10 A fuse 2 in the rear fuse block. When the work lamp on switch is pressed the BCM senses this signal on the dome fluorescent work lamp signal circuit. The BCM responds to this signal by grounding the dome fluorescent work lamp relay control circuit, energizing the relay. The relay in turn supplies voltage to the work lamps. The BCM utilizes the dome fluorescent work lamps signal circuit as a request signal when the key is in the any position except START. The work lamps are grounded at G403.
