TROUBLESHOOTING

M1542000701281

Features the headlamp automatic shutdown function
to avoid battery drain when the headlamps are left
on. The main features are as follows:

• Extinguishes automatically in three minutes if the

ignition switch is turned off with the lighting switch
on.

• Extinguishes in one second if the driver's door is

opened within that 3-minute period.

• If the headlamps are turned on with the ignition

switch off, the headlamps and tail lamps will
extinguish in three minutes after the driver's door
is opened or closed.

The headlamps are controlled by the Smart Wiring
System (SWS). For troubleshooting, refer to respec-
tive Groups below.

• Not using SWS monitor: GROUP 54B, SWS

ON-VEHICLE SERVICE

HEADLAMP AIMING

M1542000900613

PRE-AIMING INSTRUCTIONS

1. Inspect for badly rusted or faulty headlamp

assemblies.

2. These conditions must be corrected before a

satisfactory adjustment can be made.

3. Inspect tyre inflation, and adjust if it is necessary.
4. If the fuel tank is not full, place a weight in luggage

room of the 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 the headlamp lenses.
7. Place the vehicle on a level floor, perpendicular to

a flat screen 10 m away from the bulb
centre-marks on the headlamp lens.

8. Rock vehicle sideways to allow vehicle to assume

its normal position.

9. Bounce the front suspension through three

oscillations by applying the body weight to hood
or bumper.

10.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 headlamp lens to the floor. Transfer the
measurement to the screen. Horizontal tape or
mark on the screen is for reference of vertical
adjustment.

NOTE: Height from the floor to the centre of
the headlamps (Reference value): 840 mm

(3) Measure the distance from the centre line of

the vehicle to the centre of each headlamp.
Transfer the measurement to the screen.
Vertical tape or mark on the screen with
reference to the centre line of each headlamp
bulb.

HEADLAMP ADJUSTMENT

CAUTION

• Do not cover a headlamp for more than three

minutes to prevent the plastic headlamp lens
deformation.

• When adjusting one headlamp beam, make

sure that another headlamp is off by discon-
necting the connector from it. When recon-
necting the connector, make sure that the
headlamp beam is not disturbed accidentally.

1. The low-beam headlamp should project on the

screen upper edge of the beam (cut-off).

LUMINOUS INTENSITY MEASUREMENT

M1542001000538

1. Set the headlamps to high-beam.

2. Using a photometer, and following its

manufacturer's instruction manual, measure the
headlamp centre intensity and check to be sure
that the limit value is satisfied.

Limit: 30,000 cd or more {When a screen is
set 25m ahead of the vehicle}

NOTE: When measuring the intensity, maintain an
engine speed of 2,000 r/min., with the battery fully
charged.
There may be special local regulations pertaining to
headlamp intensity. Be sure to make any adjust-
ments necessary to satisfy such regulations.
If an illuminometer is used to make the measure-
ments, convert its values to photometer values by
using the following formula.

I =E x r

2

:

• I = intensity (cd)

• E = illumination (lux)

• r = distance (m) from headlamps to illuminometer

CAUTION

Do not touch the surface of the bulb with hands
or dirty gloves as the bulb may pop after a short
time. If the surface does become dirty, clean it
with alcohol or thinner, and let it dry thoroughly
before installing.
1. Disconnect the battery.
2. Disconnect the connector.
