SERVICE BJUSTMENT. PROCEDURES
SPEEDOMETER INSPECTION NOSHIAA
I. Adjust tire inflation pressure to the standard value. (Refer
to’GROUP 22 WHEELS AND TIRES-General Specifications)
2. Use speedometer tester to make sure that the speedome-
ter indication error is within the standard value.

Caution
1 When using a speedometer tester to inspect the
speedometer, be sure to chock the non-drive wheels
to prevent the vehicle from moving. Also be sure to
set the transfer shift lever to “2H”.
2 If there is a special regulation for speedometer
indication error in the area where the ‘vehicle is
operated, be sure to meet the requirement of the
regulation.
TACHOMETER INSPECTION NOBHIBA
Connect a tach-dwell meter, and then compare the meter
readings at various engine speeds with the values indicated on
the tachometer.
Standard value:
1,000 r/min
3,000 r/min
5,000 r/min f 100 r/min
2150 r/min
&250 r/min
Tgch-dwell meter Caution
The tachometer is the negative-ground type, and therefore
should not be connected in reverse polarity to the battery.
If the tachometer is connected in reverse polarity, the
transistors and diodes will be damaged.

E ADJUSTMENT PROCEDURES
T AIMING
PRE-AIMING INSTRUCTIONS 1. Test dimmer switch operation.
2. Observe operation of high beam indicator light
mounted in instrument cluster.
3. Inspect for badly rusted or faulty headlight assemblies.
These conditions must be corrected before a satisfactory ad-
justment can be made.
4. Place vehicle on a level floor.
5. Jounce front suspension through three (3) oscillations by
applying body weight to hood or bumper.
6. Inspect tire inflation.
7. Rock vehicle sideways to allow vehicle to assume its normal
position.
8. If fuel tank is not full, place a weight in trunk of vehicle to
simulate weight of a full tank [3 kg (6.5 Ibs.) per gallon].
9. There should be no other load in the vehicle other than driver
or substituted weight of approximately 70 kg (150 Ibs.) placed
in driver’s position.
10. Throughly clean headlight lenses.
11. Adjust headlights by following the instructions for the
headlight tester manufacturer.
LUMINOUS INTENSITY MEASUREMENT Measure the luminous intensity of headlights with a photometer in
accordance with the instruction manual prepared by the manufac-
turer of the photometer and make sure that the luminous intensity
is within the following limit.
Luminous intensity at the center of high intensity zone for high
beam.
Limit : 20,000 cd or more NOTE
1. When measuring the luminous intensity of headlight, keep the
engine at 2,000 rpm and have the battery charged.
2. If there are specific regulations for luminous intensity of head-
lights in the region where the vehicle is operated, make sure
that the intensity conforms to the requirements of such reg-
ulations.
