Test N: The Hazard Lamps Are Inoperative/Always On

PINPOINT TEST N: THE HAZARD LAMPS ARE INOPERATIVE/ALWAYS ON

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