to front combination lamp RH terminal 3,
through 10A fuse [No. 74, located in IPDM E/R]
through IPDM E/R terminal 28
to front combination lamp LH terminal 3.
Ground is supplied
to front combination lamp RH terminals 4, and
to front combination lamp LH terminals 4,
through grounds E17, E43 and B102 (with VDC system, navigation system or telephone)
through grounds E17, E43 and F152 (without VDC system, navigation system and telephone).
With the power and ground supplied, headlamp bulbs illuminate. High beam solenoids move the bulb shades
in the front combination lamps, and the bulb shades change to high beam position.
Unified meter and A/C amp. receives signal from BCM through CAN communication lines, and then combina-
tion meter indicator illuminates high beam.
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-III.
REMOTE KEYLESS ENTRY SYSTEM OPERATION
Refer to BL-59, "REMOTE KEYLESS ENTRY SYSTEM" .
VEHICLE SECURITY SYSTEM
The vehicle security system will flash the high beams if the system is triggered. Refer to BL-125, "VEHICLE
SECURITY (THEFT WARNING) SYSTEM" .
XENON HEADLAMP
Xenon type lamps are used for headlamps. Xenon bulbs do not use a filament. Instead, they produce light
when a high voltage current is passed between two tungsten electrodes through a mixture of xenon (an inert
gas) and certain other metal halides. In addition to strong lighting power, electronic control of the power supply
gives the headlamps stable quality and tone color.
Followings are some advantages of the xenon type headlamp.
The light produced by the headlamps is white color similar to sunlight that is easy to the eyes.
Light output is nearly double that of halogen headlamps, affording increased area of illumination.
Counter-reflected luminance increases and the contrast enhances on the wet road in the rain. That makes
visibility go up more than the increase of the light volume.
Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
CAN Communication System DescriptionNKS004WO
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.

Removal and InstallationNKS004X9
REMOVAL
1. Open the driver and front passenger window, and then disconnect the battery cable from the negative ter-
minal or remove power fuse.
CAUTION:
After battery cables are disconnected, never open/close the driver and/or front passenger door
with the window in the full up position. The automatic window adjusting function will not work and
the side roof panel may be damaged.
2. Remove front bumper fascia. Refer to EI-14, "
FRONT
BUMPER" .
3. Remove headlamp mounting bolts.
4. Pull head lamp toward vehicle front, disconnect connector, and
remove headlamp.

Servicing to Replace Headlamps When DamagedNKS004XB
If only installation part as shown in the figure is damaged, and head-
lamp housing itself is not damaged, repair can be completed easily
by installing correction brackets.
INSTALLATION OF HEADLAMP BRACKET
1. Remove headlamps. Refer to LT- 2 9 , "Removal and Installation" .
2. Cut damaged section of installation part, then shape with sand-
paper.
