Normal Operation
The smart junction box (SJB) sends a voltage reference signal to the hazard lamp switch through circuit CLS32 (BN/YE). When the hazard switch is engaged, the voltage signal is routed to ground through circuit GD116 (BK/VT). When the SJB detects a request for the hazard lamps, the SJB sends voltage to the appropriate turn lamps.

Possible Causes
- Circuit CLS32 (BN/YE) open
- Circuit GD116 (BK/VT) open
- Hazard lamp switch
- SJB
