General Information for Xenon Headlamp Trouble DiagnosisINFOID:0000000001328284
In most cases, malfunction of xenon headlamp - “does not ill uminate”, “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, fi rst 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 dr op significantly, it will flash repeatedly, or light color
will turn reddish. 30 – 6 : Continuity should exist.

When lighting switch is OFF : HEAD LAMP SW1 OFF
