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 flasher lamp switch through circuit CLN30 (GN/OG). When the hazard flasher lamp switch is pressed, the voltage signal is routed to ground through circuit GD138 (BK/WH). When the SJB detects a request for the hazard lamps, the SJB provides voltage to the appropriate turn lamps.
The hazard flasher lamp switch is a momentary contact switch.
- 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
- Hazard flasher lamp switch
- SJB
