Fog Lamp

The fog lamps operate only when the headlamp switch is in the ON position, and the operator has selected low-beam operation. When the headlamps are in high-beam operation, the fog lamps will not operate.

Circuit A3 from the Power Distribution Center (PDC) supplies current to a bus bar in the fuse block. Circuit F61 is one of four circuits that the bus bar feeds and is protected by a 10 Amp fuse in cavity 4. Circuit F61 connects to the fog lamp switch.

The fog lamp switch contains a relay that supplies current to the fog lamps. Circuit L4 from the multi-function switch supplies current to the coil side of the relay (only when the headlamps operate on low-beam). Circuit F61 supplies current to the contact side of the relay. During low-beam headlamp operation when the fog lamp switch contacts close, circuit F61 connects to circuit L39.

Circuit L39 feeds the right and left fog lamps. Circuit L39 also feeds the green LED in the switch that illuminates during fog lamp operation.

When the headlamp switch is in the PARK or ON position, circuit E1 from the headlamp switch supplies current for circuit E2 Circuit E2 contains a 4 Ampfuse in cavity 12 of the fuse block, and powers the bulb in the fog lamp switch.
