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

HEADLAMP (FOR CANADA) - DAYTIME LIGHT SYSTEM -
Revision: 2006 January2006 M35/M45
DAYTIME LIGHT OPERATION
With the engine running, the lighting switch in the OFF or AUTO position (headlamp is not illuminate) and
parking brake released, the IPDM E/R receives input request signal from BCM to turn on daytime light. This
input is communicated across the CAN communication lines. The CPU of the IPDM E/R controls the daytime
light relay coil. When energized, this relay directs power
through daytime light relay terminals 5 and 3
through front combination lamp RH terminal 2
through front combination lamp RH terminal 6
through IPDM E/R terminal 27
through 10A fuse (No. 72, located in IPDM E/R)
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 combination lamp LH terminal 2
through grounds E22 and E43.
With power and grounds supplied, the daytime lights illuminate. The high beam headlamps are now wired in
series and illuminate at a reduced intensity.

to optical sensor terminal 1.
Optical sensor, ground is supplied
to optical sensor terminal 3
through BCM terminal 18.
When ignition switch is turn to ON position, and
When outside brightness is darker than prescribed level, input is supplied
from optical sensor terminal 2
to BCM terminal 14.
The headlamps will then illuminate. For a description of headlamp operation, Refer to LT- 11 6 , "
System
Description" .
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 (or if auto light system is activated), 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.
DELAY TIMER FUNCTION
Delay timer function carries out a function that BCM activates the timer and controls lights out of headlamps by
door switch signal and lightning switch signal when turning the Ignition switch OFF while it is ON and head-
lamps are ON by the auto light function.
Timer types are a 5 minutes timer and a 45 seconds timer
When opening any door (door switch is ON), the 5 minutes timer starts and then headlamps go out five
minutes later
When all the doors are closed (from door switch ON to OFF), the 45 second timer starts and then head-
lamps go out 45 seconds later. If any door is opened (door switch ON) while the 45 seconds timer is in
operation, the 5 minutes timer starts again
The timer stops when turning on the ignition switch or turning off the auto light switch under the above
conditions.
Delay timer control mode can be changed by the function setting of CONSULT-II.
CAN Communication System DescriptionNKS003Q0
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 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 the high rate of information transmission with less wir-
ing. Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNKS003Q1
Refer to LAN-34, "CAN Communication Unit" .
Major Components and FunctionsNKS003Q2
Components Functions
BCM
Turns on/off circuits of tail light and headlamp according to signals from optical sensor, lighting switch
(AUTO), driver door switch, passenger door switch, rear door switch, and ignition switch (ON, OFF).
Optical sensor
Converts outside brightness (lux) to voltage, and sends it to BCM. (Detects brightness of 50 to 1,300 lux)
