General Information for Xenon Headlamp Trouble Diagnosis
INFOID:0000000001328284
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:
INFOID:0000000001328285
• 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 connector.
• 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.
