PINPOINT TEST E: AN INDIVIDUAL DEMAND LAMP IS INOPERATIVE

E1-E2:

Normal Operation
During the demand lighting function, the instrument cluster provides a ground for the battery saver relay through circuit 1005 (VT/OG) whenever the instrument cluster is awake. The battery saver relay provides power to circuit 54 (LG/YE). Circuit 54 (LG/YE) provides power to each demand lamp switch and when activated, provides power to the selected demand lamp. The demand lamps are grounded through circuit 57 (BK).

Possible Causes
- Circuit 54 (LG/YE) open
- Lamp assembly
