Component Parts and Harness Connector LocationNKS002V5
System DescriptionNKS002V6
Control of the headlamp system operation is dependent upon the position of the combination switch (lighting
switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives input
signal requesting the headlamps (and tail lamps) illuminate. 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 headlamp high and headlamp low relay coils. These
relays, when energized, direct power to the respective headlamps, which then illuminate.
If voltage is applied to a high beam solenoid, the bulb shade will move, even a xenon head lamp bulb comes
out, and a high beam and a low beam are changed.

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.

Control of the parking, license plate, side marker and tail lamp operation is dependent upon the position of the
lighting switch (combination switch). When the lighting switch is placed in the 1ST position, the BCM (body
control module) receives input signal requesting the parking, license plate, side marker and tail lamps to illumi-
nate. This input signal is communicated to the IPDM E/R (intelligent power distribution module engine room)
through the CAN communication lines. CPU (central processing unit) located in the IPDM E/R controls the tail
lamp relay coil. This relay, when energized, directs power to the parking, license plate, side marker and tail
lamps, which then illuminate.
The current that flows by Rear combination lamp control unit is controlled, and a tail lamp (LED) is made to
turn ON.

ILLUMINATIONPFP:27545
System DescriptionNKS002Z2
Control of illumination lamps operation is dependent upon position of lighting switch (combination switch).
When lighting switch is placed in the 1ST or 2ND position (or if auto light system is activated), BCM (body con-
trol module) receives input signal requesting illumination lamps to illuminate. This input signal is communi-
cated to 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 tail lamp relay coil. This relay, when ener-
gized, directs power to illumination lamps, which then illuminate.
Power is supplied at all times

through 10A fuse (No. 71, located in IPDM E/R)

to tail lamp relay, located in IPDM E/R, and

to CPU located in IPDM E/R.
Power is also supplied at all times

ILLUMINATION OPERATION BY LIGHTING SWITCH
With lighting switch in the 1ST or 2ND position (or if auto light system is activated), BCM receives input signal
requesting illumination lamps to illuminate. This input signal is communicated to IPDM E/R through the CAN
communication lines. The CPU located in the IPDM E/R controls tail lamp relay coil, which, when energized,
directs power
