General Precautions for Service OperationsNKS003NX
Never work with wet hands.
Xenon headlamp includes high voltage generating part. Be sure
to disconnect battery negative cable (negative terminal) or
power fuse before removing, installing, or touching the xenon
headlamp (including lamp bulb).
Turn the lighting switch OFF before disconnecting and connect-
ing the connector.
When turning the xenon headlamp on and while it is illuminated,
never touch the harness, bulb, and socket of the headlamp.
When checking the headlamp on/off operation, check it on vehi-
cle and with the power connected to the vehicle-side connector.
Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not
touch the headlamp bulb just after the headlamp is turned off, because it is very hot.
Install the xenon headlamp bulb socket correctly. If it is installed improperly, high-voltage leak or corona
discharge may occur that can melt the bulb, connector, and housing. Do not illuminate the xenon head-
lamp bulb out of the headlamp housing. Doing so can cause fire and harm your eyes.
When the bulb has burned out, wrap it in a thick vinyl bag and discard. Do not break the bulb.
Leaving the bulb removed from the headlamp housing for a long period of time can deteriorate the perfor-
mance of the lens and reflector (dirt, clouding). Always prepare a new bulb and have it on hand when
replacing the bulb.
When adjusting the headlamp aiming, turn the aiming adjustment screw only in the tightening direction. (If
it is necessary to loosen the screw, first fully loosen the screw, and then turn it in the tightening direction.)
Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.

HEADLAMP (FOR USA) - CONVENTIONAL TYPE -
Revision: 2007 April2007 M35/M45
HEADLAMP (FOR USA) - CONVENTIONAL TYPE -PFP:26010
Component Parts and Harness Connector LocationNKS003NY
System DescriptionNKS003NZ
The control of the headlamp system operation is dependent upon the position of the combination switch (light-
ing 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) across 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.

HEADLAMP (FOR USA) - CONVENTIONAL TYPE -
Revision: 2007 April2007 M35/M45
HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input signal requesting the headlamps to illuminate.
This input signal is communicated to the IPDM E/R across the CAN communication lines. The CPU located in
the IPDM E/R controls the headlamp low relay coil, which when energized, directs power
through 15A fuse (No. 76, located in IPDM E/R)
through IPDM E/R terminal 20
to front combination lamp RH terminal 8,
through 15A fuse (No. 86, located in IPDM E/R)
through IPDM E/R terminal 30
to front combination lamp LH terminal 8.
Ground is supplied
to front combination lamp RH terminal 4
to front combination lamp LH terminal 4
through grounds E22 and E43.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM receives input signal
requesting the headlamp high beams and low beams to illuminate. This input signal is communicated to the
IPDM E/R across the CAN communication lines. The CPU located in the IPDM E/R controls the headlamp
high relay coil and low relay coil, which when energized, directs power
through 15A fuse (No. 76, located in IPDM E/R)
through IPDM E/R terminal 20
to front combination lamp RH terminal 8,
through 15A fuse (No. 86, located in IPDM E/R)
through IPDM E/R terminal 30
to front combination lamp LH terminal 8,
through 10A fuse (No. 72, located in IPDM E/R)
through IPDM E/R terminal 27
to front combination lamp RH terminal 6,
through 10A fuse (No. 74, located in IPDM E/R)
through IPDM E/R terminal 28
to front combination lamp LH terminal 6.
Ground is supplied
to front combination lamp RH terminal 4
to front combination lamp LH terminal 4
to front combination lamp RH terminal 2
to front combination lamp LH terminal 2
through grounds E22 and E43.
With power and ground supplied, the high beam and low beam headlamps illuminate.
The unified meter and A/C amp. that received the high beam request signal by BCM across the CAN commu-
nication makes a high beam indicator lamp turn on in the combination meter.

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), and the ignition switch is turned
from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, then the headlamps are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
AUTO LIGHT OPERATION
Refer to LT- 11 5 , "System Description" .
CAN Communication System DescriptionNKS003O0
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 UnitNKS003O1
Refer to LAN-50, "CAN System Specification Chart" .
