HEADLAMP (FOR USA)
Revision: October 20052005 QX56
HEADLAMP (FOR USA)PFP:26010
Component Parts and Harness Connector LocationEKS00B7S
System DescriptionEKS00B7T
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, and
to headlamp high relay, located in the IPDM E/R, and
to headlamp low 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)

Aiming AdjustmentEKS00B89
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. If equipped, 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.

HEADLAMP (FOR CANADA) - DAYTIME LIGHT SYSTEM -
Revision: October 20052005 QX56
System DescriptionEKS00B8E
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
to ignition relay, located in the IPDM E/R (intelligent power distribution module engine room), and
through 50A fusible link (letter f , located in the fuse and fusible link box)
to BCM terminal 70, and
through 20A fuse (No. 53, located in the IPDM E/R)
to CPU (central processing unit) of the IPDM E/R, and
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, and
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.
