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)]

to BCM terminal 38.
When ignition switch is in ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminals 49 and 52

through grounds M35, M45 and M85,

to IPDM E/R terminals 38 and 60

through grounds E21, E50 and E51.
FRONT FOG LAMP OPERATION
The front fog lamp switch is built into combination switch. The lighting switch must be in the 2ND position or
AUTO position (headlamp 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 located in the IPDM E/R grounds the coil side of the
front fog lamp relay. The front fog lamp relay then directs power

through IPDM E/R terminal 36

to front fog lamp RH terminal 1,

through IPDM E/R terminal 37

to front fog lamp LH terminal 1.
Ground is supplied

to front fog lamp RH and LH terminals 2

through grounds E21, E50 and E51.
With power and grounds supplied, front fog lamps illuminate.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), the front fog lamp switch is ON, and
the ignition switch is turned from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the front fog lamps (and headlamps) remain illuminated for 5 minutes, then the front fog
lamps (and headlamps) are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
CAN Communication System DescriptionNKS002WY
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNKS002WZ
Refer to LAN-32, "CAN Communication Unit" .

Aiming AdjustmentNKS002X9
Front fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.

Keep all tires inflated to correct pressure.

Place vehicle on level ground.

See that vehicle is unloaded (except for full levels of coolant, engine oil and fuel, and spare tire, jack, and
tools). Have the driver or equivalent weight placed in driver seat.
Adjust aiming in the vertical direction by turning adjusting screw.
1. Set the distance between the screen and the center of front fog lamp lens as shown at left.
2. Turn front fog lamps ON.
3. Adjust front fog lamps using adjusting screw so that the top edge of the high intensity zone is 100 mm (3.94 in) below the height of
front fog lamp centers as shown at left.

When performing adjustment, if necessary, cover headlamps
and opposite front fog lamp.
