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.
OUTLINE
Power is supplied at all times
lto ignition relay (located in IPDM E/R) and
lto front fog lamp relay (located in IPDM E/R), from battery directly,
lthrough 50A fusible link (letter G, located in fuse and fusible link box)
lto BCM terminal 57,
lthrough 20A fuse (No. 52, located in IPDM E/R) and
lthrough 20A fuse (No. 53, located in IPDM E/R)
lto CPU (located in IPDM E/R),
lthrough 10A fuse [No. 19, located in fuse block (J/B)]
lto combination meter terminal 3.
With the ignition switch in the ON or START position, power is supplied

lthrough grounds M21, M80 and M83,
lto IPDM E/R terminals 38 and 59

FOG LAMP OPERATION
The front fog lamp switch is built into the combination switch. The lighting switch must be in the 1ST position,
2ND position or AUTO position (LOW beam is ON) and the front fog lamp switch must be ON for front fog lamp
operation.
With the front fog lamp switch in the ON position, the CPU of the IPDM E/R grounds the coil side of the front
fog lamp relay. The front fog lamp relay then directs power
lthrough 20A fuse (No. 56, located in IPDM E/R)
lthrough IPDM E/R terminal 50
lto front fog lamp LH terminal 1 and
lthrough IPDM E/R terminal 51
lto front fog lamp RH terminal 1.
Ground is supplied at all times
lto front fog lamp RH and LH terminal 2
lthrough grounds E21, E41 and E61.
With power and ground supplied, the front fog lamps illuminate.
