NOTES ON HEADLAMP ASSEMBLY:
Plastic outer lens are equipped with headlamp assembly. For handling, care should be taken for
the following items:
DHeadlamps should not be illuminated for more than 3 minutes with scratch preventive protectors,
etc. covered on them.
DMasking such as taping should not be attached on outer lens.
DOuter lens surface should not be rubbed with a sharp-edged tool, etc.
DSpecified wax remover should be used for insistently washing.
DAuthorized Mitsubishi Genuine bulbs should be used.
TROUBLESHOOTING
Headlamps are controlled smart wiring system (SWS). For troubleshooting, refer to GROUP 54B.
NOTE
When ETACS-ECU is defective, headlamps can be illuminated only in a low beam mode as fail-safe
function.
ON-VEHICLE SERVICE
HEADLAMP AIMING
PRE-AIMING INSTRUCTION
1. Inspect for badly rusted or faulty headlamp assemblies.
2. These conditions must be corrected before a satisfactory
adjustment can be made.
3. Inspect tyres inflation, and adjust if necessary.

CHASSIS ELECTRICAL -Headlamp Assembly54A-25
4. If the fuel tank is not full, place a weight in luggage room
of vehicle to simulate weight of a full tank 0.8 kg per litre.
5. There should be no other load in the vehicle other than
driver or substituted weight of approximately 75 kg placed
in driver’s position.
6. Thoroughly clean headlamp lenses.
7. Place the vehicle on a level floor, perpendicular to a flat
screen 10m away from the bulb center - marks on the
headlamp lens.
8. Rock vehicle sideways to allow vehicle to assume its
normal position.
9. Bounce the front suspension through three (3) oscillations
by applying the body weight to hood or bumper.
HEADLAMP ADJUSTMENT

Low Beam Adjustment
1. Four lines of adhesive tape (or equivalent markings) are
required on screen or wall:
(1) Position a vertical tape or mark so that it is aligned
with the vehicle centre line.
(2) Measure the distance from the centre - marks on the
low beam headlamp lens to the floor. Transfer the
measurement to the screen. Horizontal tape or mark
on the screen is for reference of vertical adjustment.
(3) Measure the distance from the centre line of the
vehicle to the centre of each low beam headlamp.
Transfer the measurement to the screen. Vertical
tape or mark on the screen with reference to the
centre line of each low beam headlamp bulb.
2. Check if the low beam shining onto the screen is at the
standard value.

Caution
Be sure to adjust the aiming adjustment screw in
the tightening direction.
High Beam Adjustment
1. Four lines of adhesive tape (or equivalent markings) are
required on screen or wall:
(1) Position a vertical tape or mark so that it is aligned
with the vehicle centre line.
(2) Measure the distance from the centre - marks on the
high beam headlamp lens to the floor. Transfer the
measurement to the screen. Horizontal tape or mark
on the screen is for reference of vertical adjustment.
(3) Measure the distance from the centre line of the
vehicle to the centre of each high beam headlamp.
Transfer the measurement to the screen. Vertical

3. Alternately turn the adjusting screw to adjust the headlamp
high beam aiming.
Caution
Be sure to adjust the aiming adjustment screw in
the tightening direction.

1. The headlamps should be aimed with the proper beam
setting equipment, and in accordance with the equipment
manufacture’s instructions.
NOTE
If there are any regulations pertinent to the aiming of
headlamps in the area where the vehicle is to be used,
adjust so as to meet those requirements.
2. Alternately turn the adjusting screw to adjust the headlamp
aiming. (Refer to P.54A-24.)

HEADLAMP INTENSITY MEASUREMENT
1. Using a photometer, and following its manufacture’s
instruction manual.
2. Maintain an engine speed of 2,000 r/min., with the battery
in the charging condition
3. Set the headlamps to high beam
4. Measure the headlamp centre intensity (a point of H line
and V line) and check to be sure that the limit value
is satisfied.
Limit:
High beam 30,000 cd or more per one headlamp
NOTE
1. There may be special local regulations pertaining to
headlamp intensity, be sure to make any adjustments
necessary to satisfy such regulations.
2. If an illuminometer is used to make the measurements,
convert its values to photometer values by using the
following formula.
I=Er
2Where:
I=intensity (cd)
E=illumination (lux)
r=distance (m) from headlamps to illuminometer
Caution
1. On the headlamp not yet adjusted, perform aiming
with connector removed and the lamps switched off,
if applicable. In addition, care should be taken to
prevent a change of optical axis when connector is
reconnected.
2. Plastic outer lens are equipped with headlamps. When
lens surface is covered with materials for not
penetrating light, headlamp operation time should be
within 3 minutes. In addition, masking such as taping
should not be performed.
HEADLAMP BULB (LOW BEAM)REPLACEMENT
(1) Disconnect battery.
(2) Disconnect connector.
(3) Screw out socket to pull out bulb.
(4) After bulb is replaced, properly reconnect connector.
Caution
Do not touch bulb surface bare-handed or with dirty
