Code B2498 Ford Description

The Smart Junction Box (SJB) sends voltage signals to the headlamp switch to monitor the OFF, PARKING LAMPS ON and HEADLAMPS ON positions. At any given time, the headlamp switch routes one of the input circuits to ground. When the SJB detects the headlamp switch in the HEADLAMPS ON position with the multifunction switch in the LOW BEAM position, the SJB provides voltage to the LH and RH low beam headlamps. The Diagnostic Trouble Code (DTC) set when the SJB detects multiple headlamp switch inputs active at the same time.
