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

N1-N2:

N3-N5:

Normal 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 - is an on-demand DTC that sets when the SJB detects a short to ground from the hazard flasher lamp switch input circuit.

Possible Causes
- Circuit CLN30 (GN/OG) open or short to ground
- Circuit GD138 (BK/WH) open
- Hazard flasher lamp switch
- SJB
