Fog/Driving Lamp: Description and Operation

CIRCUIT OPERATION
On vehicles equipped with optional Fog Lamps, a lamp internal to the cluster is illuminated when the system is turned ON. The lamp is powered by the fog lamp switch on circuit L29. Ground for the lamp is provided on the Z1 circuit and terminates at the instrument panel left side cowl.

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 mode, the fog lamps will not operate.

When the operator turns the fog lamps switch ON circuit L44 is connected to circuit L39. The L44 circuit is protected by a 20 amp fuse located in cavity 13 of the junction block, and powers the LOW beam headlamps.

Circuit L39 connects from the switch to the fog lamps.

Ground for the lamps is different for the left and right lamps. For the right fog lamp, the ground is provided on circuit Z1 and terminates at the right frame rail. For the left fog lamp, the ground is provided on circuit Z1 and terminates at the left strut tower.
