Test E: The Demand Lighting Is Inoperative

PINPOINT TEST E: THE DEMAND LIGHTING IS INOPERATIVE

E1-E4:

Normal Operation
The lighting control module (LCM) provides power to the demand lamps through circuit 705 (LG/OG). The demand lamps are grounded through circuit 57 (BK). The demand lamps will remain powered for a predetermined amount of time. Once that timeout has been reached, the LCM removes voltage from circuit 705 (LG/OG).

Possible Causes
- Circuit 57 (BK) open
- Circuit 705 (LG/OG) open or short to ground
- LCM
