Test N: The Hazard Lamps Are Inoperative/Always On
PINPOINT TEST N: THE HAZARD LAMPS ARE INOPERATIVE/ALWAYS ONNormal Operation
The smart junction box (SJB) sends a voltage reference signal to the hazard lamp switch through circuit CLS32 (BN/YE). The hazard flasher lamp switch is a momentary contact switch. When the hazard flasher lamp 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 provides on/off voltage to all the turn lamps.
- DTC B2071 (Hazard Switch Signal Short to Ground) - is an on-demand DTC that sets when the SJB detects a short to ground from the hazard flasher lamp switch input circuit.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Joint connector
- Hazard flasher lamp switch
- SJB
