Fog Lamp

CIRCUIT OPERATION
The fog lamps will operate only when the head lamp switch is in the ON position, and the operator has selected LOW beam operation. When the head lamps are in high beam operation, the fog lamps will not operate.

Circuit A3 from the Power Distribution Center supplies (PDC) voltage 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. Voltage to the fog lamps. Circuit L4 from the multi-function switch supplies voltage to the coil side of the relay (only when the headlamps operate on LOW beam). Circuit F61 supplies voltage 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 right and left fog lamp. Circuit L39 also feeds the green L.E.D. in the switch that illuminates during fog 1 Amps operation.

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