Component Parts and Harness Connector LocationINFOID:0000000003533332
System DescriptionINFOID:0000000003533333
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 ignition relay, located in the IPDM E/R,
• to headlamp high relay, located in the IPDM E/R,
• to headlamp low relay, located in the IPDM E/R,
• through 20A fuse (No. 53, located in the IPDM E/R)
• to CPU of the IPDM E/R, and

Coolant and engine oil filled to correct level, and fuel tank full.
- Confirm spare tire, jack and tools are properly stowed.
- Aim each headlamp individually and ensure other headlamp beam pattern is blocked from screen.
- Use adjusting screw to perform aiming adjustment
NOTE:
Basic illuminating area for adjustment should be within the range shown on the aiming chart. Adjust head-
lamps accordingly.
LOW BEAM AND HIGH BEAM
1. Turn headlamp low beam on.

CAUTION:
• Disconnect battery negative terminal before touching xenon bulb or headlamp wiring harness
assembly.
• Turn headlamp switch OFF before disconnecting headlamp harness connector.
• Do not touch bulb by hand right after being turned off. Burning may result.
• Do not touch the glass of bulb directly by hand. Keep grease and other oily substances away from it.
• Do not turn xenon bulb ON when xenon bulb is removed from front combination lamp assembly.
• After installing the bulb, be sure to install the bulb socket securely to ensure watertightness.

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
• to ignition relay, located in the IPDM E/R (intelligent power distribution module engine room),
• through 50A fusible link (letter f , located in the fuse and fusible link box)
• to BCM terminal 70,
• through 20A fuse (No. 53, located in the IPDM E/R)
• to CPU (central processing unit) of the IPDM E/R,
• through 10A fuse [No. 19, located in the fuse block (J/B)]
• to combination meter terminal 8, and
• through 10A fuse (No. 45, located in the IPDM E/R)
• to daytime light relay terminals 2 and 5.
When the ignition switch is in ON or START position, power is supplied
• to ignition relay, located in the IPDM E/R,
• through 10A fuse (No. 59, located in the fuse and relay box)
• to BCM terminal 38, and
• through 10A fuse [No. 14, located in the fuse block (J/B)]
• to combination meter terminal 24.
Ground is supplied
• to BCM terminal 67 and
• to combination meter terminal 17
• 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 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
• to 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 front 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.

FRONT FOG LAMP

System DescriptionINFOID:0000000003533389
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,
• to front fog lamp relay, located in the IPDM E/R,
• 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)
• to BCM terminal 70.
When the ignition switch is in ON or START position, power is supplied
• to ignition relay, located in the IPDM E/R, and

• through grounds M57, M61 and M79, and
• to IPDM E/R terminals 38 and 59
• through grounds E9, E15 and E24.
FOG LAMP OPERATION
The fog lamp switch is built into the combination switch. The lighting switch must be in the 2ND position or
AUTO position (LOW beam is ON) and the fog lamp switch must be ON for fog lamp operation.

Aiming AdjustmentINFOID:0000000003533400
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.
