Trouble Diagnoses
NHEL0258
WARNING:
I
The xenon headlamp has a high-tension current generating area. Be extremely careful when remov-
ing and installing. Be certain to disconnect the battery negative cable prior to removing or install-
ing.
I
When the xenon headlamp is lit, do not touch the harness (covered with red or amber insulation),
bulb itself or the bulb socket with your bare hands.
I
Never service a xenon headlamp with wet hands.
I
When checking body side harness with a circuit tester, be certain to disconnect the harness con-
nector from the xenon headlamp.
I
When the xenon headlamp is lit, the xenon bulb must be installed in the headlamp housing. (Never
