HEADLAMP - XENON TYPE -
Revision: 2005 July 2005 FX
General Information for Xenon Headlamp Trouble DiagnosisAKS00CHH
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:AKS00CHI

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 DiagnosisAKS00CHJ
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]
