LRemove the driver's dashboard lower cover and
knee bolster (see section 20).
Disconnect the connectors from the daytime run-
ning lights control unit.
Inspect the connector and socket terminals to be
sure they are all making good contact.
lf the terminals are bent, loose or corroded. repair
them as necessary, and recheck the system.
lf the terminals look OK, make the following
input tests at the connector,- lf any test indicates a problem, find and correct
the cause, then recheck the system.- lf all the input tests prove OK, the control unit
must be faulty; replace it.

1. Open the hood.
2. Check the horizontal adjustment indicator.
The "0" mark on the horizontal indicator gear
should be aligned with the mark on the horizontal
indicator.
HORIZONTAL INDICATOR
Check the vertical adjustment indicator. The bubble
should be centered underneath the longest scribe
mark on the gauge.
VERTICAL INDICATOR:
Headlight become very hot in use; do not touch them
or any attaching hardware immediately after they
have been turnsd off.

lf either indicator is not aligned with its "0"mark as
described left column, an adjustment can be made
by using a Phillips screwdriver.
Adjust the headlights to local requirements by turn-
ing the adjusters.
After headlight replacement, it may bs necessary to
readjust the horizontal indicator gear.
. First install the headlioht, and adjust its horizon-
tal and vertical aimings according to local re-
quirements.
. Then check that the arrow on the horizontal indi-
cator gear is aligned with the mark on the hori-
zontal indicator.- lf they are not aligned, remove the screw,
adiust the indicator gear, and retighten the
screw.
NOTE: As the outer lenses are made ot an acryli-
coated, polycarbonated material, do not cover the
headlights when they are turned on.

Adjustment (cont'dl
Turn the low beams on.
Determine if the headlights are aimed properly.
Vsrtical adiustmsnt:
Measure the height of the headlights (A). The lights
should reflect 52 mm \2.1 in.) below (B) headlight
height.
Horizontal adi$tment:
The width of the refracting points (C) should be the
same as the width of the headlight central points (D,

ments by turning the horizontal adjuster (A) and the
vertical adjuster (B).
After headlight replacement, it may be necessary to
readjust the horizontal indicator gear.

and vertical aimings according to local require-
ments.

cator gear is aligned with the mark on the hori-
zontal indicator,- lf they are not aligned, remove the screw, adjust
the indicator gear, and retighten the screw.
