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-116, "System Description" .
XENON HEADLAMP
Xenon type lamps are used for to the low beam 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 DescriptionNKS003OM
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 UnitNKS003ON
Refer to LAN-34, "CAN Communication Unit" .

General Information for Xenon Headlamp Trouble DiagnosisNKS003P2
In most cases, malfunction of xenon headlamp - "does not illuminate", "flickers" or "dark" - is caused by a mal-
functioning xenon bulb. A HID control unit or lamp housing, however, may be a cause of malfunction. Be sure
to perform trouble diagnosis following the steps described below.
Caution:NKS003P3
Installation or removal of connector must be done with lighting switch OFF.
Disconnect the battery cable from the negative terminal or remove power fuse.
When the lamp is illuminated (when lighting switch is ON), never touch harness, HID control unit, inside of
lamp, or lamp metal parts.
To check illumination, temporarily install lamp in vehicle. Be sure to connect power at vehicle side connec-
tor.
If error can be traced directly to electrical system, first check for items such as blown fuses and fusible
links, broken wires or loose connectors, dislocated terminals, and improper connections.
Never work with wet hands.
Using a tester for HID control unit circuit trouble diagnosis is prohibited.
Disassembling HID control unit or harnesses (bulb socket harness, ECM harness) is prohibited.
Immediately after illumination, light intensity and color will fluctuate, but there is nothing wrong.
When bulb has come to end of its life, brightness will drop significantly, it will flash repeatedly, or light color
will turn reddish.
Xenon Headlamp Trouble DiagnosisNKS003P4
1. CHECK 1: XENON HEADLAMP LIGHTING
Install normal xenon bulb to corresponding xenon bulb headlamp, and check if lamp lights up.
OK or NG
OK >> Replace xenon bulb.
NG >> GO TO 2.
2. CHECK 2: XENON HEADLAMP LIGHTING
Install normal HID control unit to corresponding xenon headlamp, and check if lamp lights up.
OK or NG
OK >> Replace HID control unit.
NG >> GO TO 3.
3. CHECK 3: XENON HEADLAMP LIGHTING
Install normal xenon lamp housing assembly to corresponding xenon headlamp, and check if lamp lights up.
OK or NG
OK >> Replace xenon headlamp housing assembly. [Malfunction in starter (boosting circuit) in xenon
headlamp housing]
NG >> INSPECTION END
