General Information for Xenon Headlamp Trouble Diagnosis

NKS002TH

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:

NKS002TI

●

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 Diagnosis

NKS002TJ

LOW BEAM OPERATION

When the lighting switch is in 2ND position, BCM detects the HEAD LAMP1 and 2 (ON) by BCM combination
switch reading function. BCM sends low beam request signal (ON) through CAN communication.
When receiving low beam request signal (ON), IPDM E/R turns ON headlamp low relay in IPDM E/R. IPDM E/
R supplies power

●

With power and ground supplied, headlamp low beams illuminate.

HIGH BEAM OPERATION

When the lighting switch is in HIGH BEAM position and then also in 2ND position, BCM detects the HEAD
LAMP1, 2 (ON) and the HI BEAM (ON) by BCM combination switch reading function. BCM sends low beam
request signal (OFF) and high beam request signal (ON) through CAN communication.
When receiving those signals, IPDM E/R turns OFF head lamp low relay and turns ON headlamp high relay in
IPDM E/R. IPDM E/R supplies power

●

FLASH-TO-PASS OPERATION

When the lighting switch is in PASSING position, BCM detects the PASSING (ON) by BCM combination switch
reading function. BCM sends high beam request signal (ON) through CAN communication.
When receiving high beam request signal (ON), IPDM E/R turns ON headlamp high relay in IPDM E/R. IPDM
E/R supplies power

●

through 10A fuse (No. 72, located in IPDM E/R)

●

through IPDM E/R terminal 27

●

to front combination lamp RH terminal 1,

●

through 10A fuse (No. 74, located in IPDM E/R)

●

through IPDM E/R terminal 28 

●

to front combination lamp LH terminal 1.

Ground is supplied

●

to front combination lamp RH and LH terminals 5

●

through grounds E13, E26 and E28.

With power and ground supplied, headlamp high beams illuminate.
Unified meter and A/C amp. receives high beam request signal (ON) through CAN communication, and makes
high beam indicator lamp turn ON in combination meter.

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, and 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-84, "System Description"

 .

VEHICLE SECURITY SYSTEM

The vehicle security system will flash the high beams if the system is triggered. Refer to 

BL-204, "VEHICLE

SECURITY (THEFT WARNING) SYSTEM"

 .

CAN Communication System Description

NKS001NO

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.
