B2071 LINCOLN Description
The Smart Junction Box (SJB) sends a voltage signal to the multifunction switch. When the hazard flasher 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. The hazard flasher lamp switch is a momentary contact switch. The Diagnostic Trouble Code (DTC) sets when the SJB detects a short to ground from the hazard flasher lamp switch input circuit.
