Normal 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 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
- Joint connector
- Hazard flasher lamp switch
- SJB

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
