General Information for Xenon Headlamp Trouble DiagnosisBKS001NC
In most cases, malfunction of xenon headlamp - “does not illuminate”, “flickers” or “dark” - is caused by an
abnormal xenon bulb. An abnormal HID control unit or lamp housing, however, may be a cause. Be sure to
perform trouble diagnosis following the steps described below.
Caution:BKS001ND

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

When the lamp is illuminated (when the lighting switch is ON), never touch the harness, HID control unit,
inside of the lamp, or the lamp metal parts.

To check illumination, temporarily install lamp in the vehicle. Be sure to connect power at the vehicle side
connector.

If the error can be traced directly to the electrical system, first check for items such as burned-out fuses
and fusible links, broken wires or loose connectors, pulled-out terminals, and improper connections.

Never work with wet hands.

Using a tester for HID control unit circuit trouble diagnosis is prohibited.

Disassembling the HID control unit or harnesses (bulb socket harness, ECM harness) is prohibited.

Immediately after illumination, the light intensity and color will fluctuate, but there is nothing wrong.

When the bulb has reached the end of its lifetime, the brightness may drop significantly, it may flash
repeatedly, or the light may turn a reddish color.
Xenon Headlamp Trouble DiagnosisBKS001NE
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.
NG >> INSPECTION END

ADJUSTMENT USING AN ADJUSTMENT SCREEN (LIGHT/DARK BORDERLINE)
If the vehicle front body has been repaired and/or the headlamp assembly has been replaced, check aiming.
Use the aiming chart shown in the figure.

Basic illumination area for adjustment should be within the range shown on the aiming chart.
Adjust headlamp accordingly.

With the ignition switch in the ON or START position, power is supplied

to ignition relay (located in IPDM E/R),

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

to BCM terminal 38,

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

to combination meter terminal 8.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminal 52 and

to combination meter terminals 10, 11 and 12

through grounds M71 and M72,

to IPDM E/R terminals 38 and 60

through grounds E1 and E31.
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

through 15A fuse (No. 76, located in IPDM E/R)

through IPDM E/R terminal 20

to front combination lamp RH terminal 1,

through 15A fuse (No. 86, located in IPDM E/R)

through IPDM E/R terminal 30

to front combination lamp LH terminal 1.
Ground is supplied

to front combination lamp RH and LH terminals 5

through grounds E1 and E31.
With power and ground supplied, low beam headlamp illuminates.
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 (ON) and high beam request signal (ON) through CAN communication.
When receiving those signals, IPDM E/R turns ON headlamp low relay and headlamp high relay in IPDM E/R.
IPDM E/R supplies power

through 15A fuse (No. 76, located in IPDM E/R)

through IPDM E/R terminal 20

to front combination lamp RH terminal 1,

through 15A fuse (No. 86, located in IPDM E/R)

through IPDM E/R terminal 30

to front combination lamp LH terminal 1,

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

through IPDM E/R terminal 27

to front combination lamp RH terminal 9,

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

through IPDM E/R terminal 28

to front combination lamp LH terminal 9.
Ground is supplied

to front combination lamp RH and LH terminals 5, and
