PINPOINT TEST M: THE HAZARD LAMPS ARE ALWAYS ON

Normal Operation
The smart junction box (SJB) sends a voltage reference signal to the hazard switch through circuit 1689 (RD/WH). When the hazard switch is pressed, the signal is routed to ground through circuit 1205 (BK).

Possible Causes
- Circuit 1689 (RD/WH) short to ground
- Hazard switch
- SJB
