Normal Operation
The SJB monitors the headlamp switch position. When the headlamp switch is in the parking lamps ON position, the SJB supplies voltage to the
parking and license lamps. If a problem is detected with any of the signal circuits to the headlamp switch, the SJB will default the parking lamps and
headlamps ON. The LH front parking/turn lamp and side marker are supplied voltage from circuit 1340 (DG). The RH front parking/turn lamp and
side marker are supplied voltage from circuit 1339 (BK/PK). The LH auxiliary parking lamp is supplied voltage from circuit 1344 (VT/LB). The RH
signal mirror is supplied voltage from circuit 1343 (PK/OG). The LH rear lamp is supplied voltage from circuit 1364 (DB/YE). The RH rear turn
lamp is supplied voltage from circuit 1366 (TN/RD). The license lamps are supplied voltage from circuit 1370 (DG/LG).
