Circuit Operation

CIRCUIT OPERATION
Circuit A3 in the Power Distribution Center (PDC) connects to a bus bar in the fuse block. One of the four circuits powered by the bus bar is circuit F33. Circuit F33 connects to the headlamp switch. A 40 Amp fuse in the PDC protects the A3 circuit. A 15 Amp fuse, in cavity 2 of the fuse block, protects the F33 circuit.

The headlamp switch has 3 positions, ON, PARK (tail lamps) and OFF, plus a dimmer switch. When the headlamp switch is in the PARK or ON position, the switch connects circuit F33 to circuit L7. From the headlamp switch, circuit L7 branches to power the front parking lamps and rear tail lamps, side marker lamps, and rear license plate lamp.

On vehicles equipped with Remote Keyless Entry (RKE) the L7 circuit is spliced to the RKE module. When the operator has activated the PANIC mode with the key fob, the RKE module supplies power to the front and rear parking lamps for a specified amount of time flashing the lamps.
