Normal Operation
The smart junction box (SJB) sends a voltage reference signal to the hazard lamp switch through circuit 385 (WH/RD). When the hazard switch is pressed, the voltage signal is routed to ground through circuit 1205 (BK). The hazard switch is a momentary contact switch.

Possible Causes
- Circuit 385 (WH/RD) open
- Circuit 1205 (BK) open
- Hazard switch
- SJB
