D1-D2:

Normal Operation
Circuit 1005 (VT/OG) provides voltage to each demand lamp when activated. The demand lamps are grounded through circuit 57 (BK). The battery saver function of the smart junction box (SJB) deactivates the voltage to the demand lamps after time-out.

Possible Causes
- Circuit 1005 (VT/OG) open
- Circuit 57 (BK) open
- Lamp assembly
