FRONT FOG LAMPPFP:26150
Component Parts and Harness Connector LocationEKS00P3Y
System DescriptionEKS00P3Z
The control of the front fog lamps is dependent upon the position of the combination switch (lighting switch).
The lighting switch must be in the 1ST position, 2ND position or AUTO position (LOW beam is ON) for front
fog lamp operation. When the lighting switch is placed in the front fog lamp position, the BCM (body control
module) receives input signal requesting the front fog lamps to illuminate. When the headlamps are illumi-
nated, this input signal is communicated to the IPDM E/R (intelligent power distribution module engine room)
through the CAN communication. The CPU (central processing unit) of the IPDM E/R controls the front fog
lamp relay coil. When activated, this relay directs power to the front fog lamps.

Power is supplied at all times
