HEADLAMP - XENON TYPE -

General Information for Xenon Headlamp Trouble Diagnosis

NKS002NX

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:

NKS002NY

●

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.
