Test Q: The Hazard Lamps Are Always On

PINPOINT TEST Q: THE HAZARD LAMPS ARE ALWAYS ON

Q1-Q3:

Normal Operation
The smart junction box (SJB) sends a reference signal to the hazard switch through circuit 1689 (RD/WH). When the hazard switch is pressed, the voltage signal is routed to ground through circuit 570 (BK/WH). When the SJB detects a hazard lamps request, the SJB sends voltage to all the turn lamps.

The timed on/off cycle is determined in the SJB and is set to flash approximately 80 times per minute if all hazard lamps operate correctly.

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