General Information for Xenon Headlamp Trouble DiagnosisNKS004X4
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:NKS004X5

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

Component Parts and Harness Connector LocationNKS004XC
System DescriptionNKS004XD

BCM (Body Control Module) controls headlamps low beam, high beam and daytime light operation.

Daytime light system operates parking, license plate, side marker, tail lamps and headlamp low beam
according to signals from unified meter and A/C amp. (receive parking brake switch signal through CAN
communication), ECM (receive engine status signal through CAN communication), lighting switch, and
ignition switch.

IPDM E/R (Intelligent Power Distribution Module Engine Room) operates parking, license plate, side
marker, tail lamps, headlamp bulbs and high beam solenoids according to CAN communication signals
from BCM.

Unified meter and A/C amp. operates high beam indicator lamp according to CAN communication signals
from BCM.

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 through CAN communication. The CPU located in the
IPDM E/R controls the headlamp low relay turned ON, which when energized, supplies power,

through 15A fuse [No. 76, located in IPDM E/R]

through IPDM E/R terminal 20

to front combination lamp RH terminal 7,

through 15A fuse [No. 86, located in IPDM E/R]

through IPDM E/R terminal 30

to front combination lamp LH terminal 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 power and ground supplied, headlamp bulbs 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 headlamp high beams to illuminate. High beam request signal and low beam request signal is com-
municated to the IPDM E/R through CAN communication. The CPU located in the IPDM E/R controls head-
lamp high relay and headlamp low relay turned ON, which when energized, supplies power,

through 15A fuse [No. 76, located in IPDM E/R]

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, and then combination
meter indicator illuminates high beam,
DAYTIME LIGHT OPERATION
Once the parking brake is turned OFF after ignition switch ON, if the lighting switch is turned OFF while engine
is running, the BCM outputs the signal requesting parking, license plate, side marker, tail lamps and headlamp
low beam to illuminate. This output signal is communicated to the IPDM E/R through CAN communication.
