3. CHECK OPTICAL SENSOR SIGNAL CIRCUIT
1. Check continuity (open circuit) between BCM harness connector M3 terminal 14 and optical sensor harness connector M37 ter-
minal 2.
2. Check continuity (short circuit) between BCM harness connector M3 terminal 14 and ground.
OK or NG
OK >> GO TO 4.
NG >> Repair harness or connector.
4. CHECK OPTICAL SENSOR GROUND CIRCUIT
1. Check continuity (open circuit) between BCM harness connector M3 terminal 18 and optical sensor harness connector M37 ter-
minal 3.
2. Check continuity (short circuit) between BCM harness connector M3 terminal 18 and ground.
OK or NG
OK >> GO TO 5.
NG >> Repair harness or connector.
5. CHECK OPTICAL SENSOR VOLTAGE
1. Connect BCM connector.
2. Turn ignition switch ON.
3. Check voltage between BCM harness connector M3 terminal 17 and ground.
OK or NG
OK >> Replace optical sensor.
NG >> Replace BCM. Refer to BCS-15, "
Removal and Installa-
tion of BCM" .
14 – 2 : Continuity should exist.
14 – Ground : Continuity should not exist.

FRONT FOG LAMP
Revision: 2006 December 2006 FX35/FX45
FRONT FOG LAMPPFP:26150
Component Parts and Harness Connector LocationNKS002WW
System DescriptionNKS002WX
Control of the front fog lamps is dependent upon the position of the combination switch (lighting switch). The
lighting switch must be in the 2ND position or AUTO position (headlamp is ON) for front fog lamp opera-
tion.When the lighting switch is placed in the front fog lamp on position the BCM (body control module)
receives input signal requesting the front fog lamps to illuminate. When the headlamps are illuminated, this
input signal is communicated to the IPDM E/R (intelligent power distribution module engine room) through the
CAN communication lines. The CPU (central processing unit) located in 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
to ignition relay, located in IPDM E/R, from battery direct,
through 15A fuse (No. 88, located in IPDM E/R)
to front fog lamp relay, located in IPDM E/R,
through 15A fuse (No. 78, located in IPDM E/R)
to CPU located in IPDM E/R,
through 10A fuse (No. 71, located in IPDM E/R)
to CPU located in IPDM E/R.
Power is also supplied at all times
through 50A fusible link (letter M, located in fuse, fusible link and relay box)
to BCM terminal 55,
through 15A fuse [No. 22, located in fuse block (J/B)]
to BCM terminal 42.
When ignition switch is in ON or START position, power is supplied
through 15A fuse [No. 1, located in fuse block (J/B)]
