1. CHECK HEADLAMP TURN OFF
Make sure that lighting switch is OFF. And check if headlamp turns off when ignition switch is turned OFF.
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
2. CHECK COMBINATION SWITCH INPUT SIGNAL
CONSULT-III DATA MONITOR
1. Select "HEAD LAMP1" and "HEAD LAMP2" of BCM data monitor item.
2. With operating the lighting switch, check the monitor status.
OK or NG
OK >> Replace IPDM E/R. Refer to PG-26, "Removal and Installation of IPDM E/R" .
NG >> Check combination switch (lighting switch). Refer to LT- 9 2 , "
Combination Switch Inspection" .
3. CHECKING CAN COMMUNICATIONS BETWEEN BCM AND IPDM E/R
Perform self-diagnosis for “BCM” with CONSULT-III.
Display of self-diagnosis results
NO DTC>> Replace IPDM E/R. Refer to PG-26, "Removal and Installation of IPDM E/R" .

nosis)" .
General Information for Xenon Headlamp Trouble DiagnosisNKS004XV
In most cases, malfunction of xenon headlamp - “does not illuminate”, “flickers” or “dark” - is caused by a mal-
functioning xenon bulb. A malfunctioning HID control unit or lamp housing, however, may be a cause. Be sure
to perform trouble diagnosis following the steps described below.
Caution:NKS004XW

Installation or removal of connector must be done with lighting switch OFF.

Disconnect the battery cable from the negative terminal or remove power fuse.
CAUTION:
After the 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.

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.When lighting switch is OFF : HEAD LAMP SW1 OFF
: HEAD LAMP SW2 OFF

System DescriptionNKS004Y4
TURN SIGNAL OPERATION
When the ignition switch is in ON or START position, power is supplied

through 10A fuse [No.1, located in fuse block (J/B)]

to BCM (body control module) terminal 38,

through 10A fuse [No.12, located in fuse block (J/B)]

to unified meter and A/C amp. terminal 22,

through 10A fuse [No.14, located in fuse block (J/B)]

to combination meter terminal 23.
Ground is supplied

to BCM terminal 52

to unified meter and A/C amp. terminals 29 and 30, and

to combination meter terminals 10, 11 and 12

through grounds M30 and M66.
LH Turn Signal Lamp
When the turn signal switch is moved to the left position, the BCM receives left turn signal by combination
switch reading function (Refer to BCS-3, "
COMBINATION SWITCH READING FUNCTION" ). Power is sup-
plied

through BCM terminal 45

to front combination lamp LH terminal 2
