Fog/Driving Lamp: Description and Operation

When the park lamps are on, battery positive voltage (B+) is applied through IP fuse block INT LPS Fuse via CKT 32 (YEL) to the fog lamp switch. Battery positive voltage (B+) is applied at all times through IP fuse block FOG LAMPS Fuse via CKT 1840 (ORN) to the switch side of the fog lamp enable relay position C. When the fog lamp switch is placed in the ON position, battery positive voltage (B+) is applied to the coil of the fog lamp enable relay position C. The coil receives ground through the Lamp Control Module (LCM). With the fog lamp enable relay position C coil energized, its contacts close, applying battery positive voltage (B+) to the fog lights. If the high beam headlamps are turned on, the LCM removes the ground from the lamp enable relay position C and the fog lights go out.
