est, 3 being the highest headlight beam vertical set-
ting.
When performing a headlamp beam pattern align-
ment on a vehicle equipped with headlamp leveling,
be certain the headlamp leveling switch is in the "0"
position before starting. Failure to do so will result in
and incorrect headlamp unit alignment.

OPERATION

With the rotation of the headlamp leveling switch
control knob, voltage is adjusted at the headlamp lev-
eling switch (rheostat). This signals the headlamp
leveling motors to adjust the vertical headlamp beam
pattern accordingly. Headlamps must be ON in order
for the leveling system to function.
DIAGNOSIS AND TESTING - HEADLAMP
LEVELING MOTOR - EXPORT
NOTE: The battery must be completely charged
(12.4v) prior to testing. It may also be necessary to
install a battery charger on the vehicles electrical
system when performing this test.
(1) Rotate the headlamp switch (low beam) to the
ON position.

(2) Disconnect the headlamp wire harness jumper
electrical connector (Fig. 20). This connector can be
accessed by opening the lamp access panel, found in
the appropriate front wheel well splash shield.

(3) Check PIN #1 for battery voltage (Fig. 21). If
no voltage is present, trace circuit until open or short
is found. Refer to Wiring Diagrams for complete sche-
matic.
(4) Check PIN #2 for ground (Fig. 21). If ground is
not present, trace circuit until open or short is found.
Refer to Wiring Diagrams for complete schematic.
(5) Check PIN #3 for headlamp leveling sense volt-
age (2.83 – 8.60v) (Fig. 21). If voltage is incorrect or
not present, trace circuit until open or short is found.
(Refer to 8 - ELECTRICAL/LAMPS/LIGHTING -
EXTERIOR/HEADLAMP
DIAGNOSIS AND TESTING) for further informa-
tion.
(6) If no open or short is found, and headlamp lev-
eling system is still inoperative, replace the head-
lamp leveling motor (Refer to 8 - ELECTRICAL/
LAMPS/LIGHTING
LEVELING MOTOR - REMOVAL).

REMOVAL

(1) Remove headlamp unit (Refer to 8 - ELECTRI-
CAL/LAMPS/LIGHTING - EXTERIOR/HEADLAMP
UNIT - REMOVAL).
(2) Disconnect headlamp leveling motor electrical
connector.
(3) Rotate leveling motor one quarter turn counter-
clockwise. This will free leveling motor housing from
the headlamp unit.
