HEADLAMP (FOR USA)
Revision: August 20072004 QX56
HEADLAMP (FOR USA)PFP:26010
Component Parts and Harness Connector LocationEKS0079P
System DescriptionEKS0079Q
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
requesting the headlamps (and tail lamps) illuminate. This input is communicated to the IPDM E/R (intelligent
power distribution module engine room) across the CAN communication lines. The CPU (central processing
unit) of the IPDM E/R controls the headlamp high and headlamp low relay coils. When energized, these relays
direct power to the respective headlamps, which then illuminate.
OUTLINE
Power is supplied at all times
to headlamp high relay, located in the IPDM E/R, and
to headlamp low relay, located in the IPDM E/R, and
to ignition relay, located in the IPDM E/R, and
through 20A fuse (No. 53, located in the IPDM E/R)
to CPU of the IPDM E/R, and
through 10A fuse [No. 19, located in the fuse block (J/B)]

For details, refer to the regulations in your state.
Before performing aiming adjustment, check the following.
1. Ensure all tires are inflated to correct pressure.
2. Place vehicle and screen on level surface.
3. Ensure there is no load in vehicle other than the driver (or equivalent weight placed in driver's position).
Coolant and engine oil filled to correct level, and fuel tank full.
4. Confirm spare tire, jack and tools are properly stowed.
5. Confirm headlamp aiming switch is set to "0" (zero) position.
LOW BEAM AND HIGH BEAM
NOTE:
Aim each headlamp individually and ensure other headlamp beam pattern is blocked from screen.
1. Turn headlamp low beam on.
2. Use adjusting screw to perform aiming adjustment.

Revision: August 20072004 QX56
System DescriptionEKS007AB
Daytime light system turns on daytime light lamps while driving. Daytime light lamps are not turned on if
engine is activated with parking brake applied. Release parking brake to turn on daytime light lamps. The
lamps turn off when lighting switch is in the 2ND position or AUTO position (Headlamp is "ON") and when light-
ing switch is in the PASSING position. (Daytime light lamps are not turned off only by parking brake itself.)
A parking brake signal and engine run or stop signal are sent to BCM (body control module) by CAN commu-
nication line.
OUTLINE
Power is supplied at all times
through 10A fuse [No. 19, located in the fuse block (J/B)]
to combination meter terminal 8, and
through 50A fusible link (letter f , located in the fuse and fusible link box)
to BCM terminal 70, and
through 10A fuse [No. 45, located in the IPDM E/R (intelligent power distribution module engine room)]
to daytime light relay terminals 2 and 5.
When the ignition switch is in ON or START position, power is supplied
through 10A fuse [No. 14, located in the fuse block (J/B)]
to combination meter terminal 24, and
through 10A fuse (No. 59, located in the fuse and relay box)
to BCM terminal 38.
Ground is supplied
to combination meter terminal 17 and
to BCM terminal 67
through grounds M57, M61 and M79.
DAYTIME LIGHT OPERATION
With the engine running, the lighting switch in the OFF or 1ST position and parking brake released, the IPDM
E/R receives input requesting the daytime lights illuminate. This input is communicated across the CAN com-
munication lines. The CPU (central processing unit) of the IPDM E/R controls the daytime light relay coil.
When energized, this relay directs power
through daytime light relay terminal 3
to front combination lamp LH terminal 2
through front combination lamp LH terminal 6
through IPDM E/R terminal 55
through 10A fuse (No. 35, located in the IPDM E/R)
through 10A fuse (No. 34, located in the IPDM E/R)
through IPDM E/R terminal 56
to front combination lamp RH terminal 6.
Ground is supplied
to combination lamp RH terminal 2
through grounds E9, E15 and E24.
With power and ground supplied, the daytime lights illuminate. The high beam headlamps are now wired in
series and illuminate at a reduced intensity.

System DescriptionEKS007B5
Control of the fog lamps is dependent upon the position of the combination switch (lighting switch). The light-
ing switch must be in the 2ND position or AUTO position (LOW beam is ON) for front fog lamp operation.
When the lighting switch is placed in the fog lamp position, the BCM (body control module) receives input sig-
nal requesting the fog lamps to illuminate. When the headlamps are illuminated, this input signal is communi-
cated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication
lines. The CPU (central processing unit) of the IPDM E/R controls the front fog lamp relay coil. When acti-
vated, this relay directs power to the front fog lamps.
OUTLINE
Power is supplied at all times
to ignition relay, located in the IPDM E/R, and
to front fog lamp relay, located in the IPDM E/R, and
through 20A fuse (No. 53, located in the IPDM E/R)
to CPU of the IPDM E/R, and
through 50A fusible link (letter f , located in the fuse and fusible link box)

FRONT FOG LAMP
Revision: August 20072004 QX56
Aiming AdjustmentEKS007BF
The 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 the adjustment
screw.
NOTE:
Access adjustment screw from underneath front bumper. Turn screw
clockwise to raise pattern and counterclockwise to lower pattern.
1. Set the distance between the screen and the center of the fog
lamp lens as shown.
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 200 mm (7.9 in) below the height of
the fog lamp centers as shown.
When performing adjustment, if necessary, cover the headlamps
and opposite fog lamp.

PARKING, LICENSE PLATE AND TAIL LAMPS
Revision: August 20072004 QX56
PARKING, LICENSE PLATE AND TAIL LAMPSPFP:26550
Component Parts and Harness Connector LocationEKS007CD
System DescriptionEKS007CE
Control of the parking, license plate, 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 illuminate.
This input signal is communicated to the IPDM E/R (intelligent power distribution module engine room) across
the CAN communication lines. The CPU (central processing unit) of the IPDM E/R controls the tail lamp relay
coil. This relay, when energized, directs power to the parking, license plate and tail lamps, which then illumi-
nate.
Power is supplied at all times
to tail lamp relay, located in the IPDM E/R, and
through 20A fuse (No. 53, located in the IPDM E/R)
to CPU of the IPDM E/R, and
to ignition relay, located in the IPDM E/R, and
through 50A fusible link (letter f , located in the fuse and fusible link box)
to BCM terminal 70.
With the ignition switch in the ON or START position, power is supplied
through 10A fuse (No. 59, located in the fuse and relay box)
to BCM terminal 38, and
to ignition relay, located in the IPDM E/R.
Ground is supplied
to BCM terminal 67
through grounds M57, M61 and M79, and
to IPDM E/R terminals 38 and 59
