Normal Operation
The battery saver relay, integral to the central junction box (CJB) provides power to the demand lamps. Any demand lamp switch, when activated provides power to the selected demand lamp. The demand lamps are energized anytime the CJB activates the battery saver relay. The instrument cluster grounds the battery saver relay through circuit 1005 (VT/OG). When the relay is energized, voltage is supplied to the demand lamp circuits on circuit 705 (LG/OG).
Possible Causes
- Fuse
- Circuit 705 (LG/OG) open
- Circuit 1005 (VT/OG) open
- Instrument cluster
- CJB
