HEADLAMP - XENON TYPE -

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
