Test N: The Hazard Lamps Are Inoperative/Always On
PINPOINT TEST N: THE HAZARD LAMPS ARE INOPERATIVE/ALWAYS ONNormal Operation
The SJB sends a voltage reference signal to the hazard flasher switch through circuit CLS32 (BN/YE). When the hazard flasher lamp switch is engaged, the voltage signal is routed to ground. When the SJB detects a request for the hazard lamps, the SJB sends on/off voltage to all the turn lamps.
The hazard flasher lamp switch is a momentary contact switch.
