TACHOMETER CHECK
1. Insert paper clip (Zem clip) from harness side of the probe
for detection of engine speed to connect engine speed
indicator.
2. Compare measured values of individual engine speed
with tachometer values, and ensure that indication
allowance is within standard value.
Standard value:
Engine speed (rpm)Indication allowance of tachometer
rpm
700±70
2,000- 100 +150
3,000- 100 +225
4,000- 125 +275
5,000- 125 +325
6,000- 125 +375
7,000- 100 +400
8,000+400
FUEL GAUGE UNIT CHECK
Remove fuel gauge unit from fuel tank.
BASIC RESISTANCE OF FUEL GAUGE UNIT
1. When float of fuel gauge unit is in Position F and E,
ensure that resistance between fuel gauge unit terminal
and earth terminal is within standard value.
Standard Value:
Float PositionMain fuel gauge unitSub fuel gauge unit
Position F2±1Ω2±1Ω
Position E41±1Ω69±1Ω
2. When float is moved slowly between Position F and E,
also ensure that resistance is smoothly changing.

ensure that Position F (A) and E (B) are within standard
value.

ENGINE COOLANT TEMPERATURE GAUGE
UNIT CHECK
1. Drain coolant. (Refer to GROUP 14 - On-vehicle Service)
2. Remove water temperature gauge unit.
3. Put water temperature gauge unit into the hot water in
specified temperature, and ensure that basic resistance
is within standard value.
Standard value: 70_C 104±13.5Ω
Reference value:

4. After inspection, apply specified sealant at threads of
water temperature gauge unit, and tighten to the specified
torque.
Semi-drying sealant: 3M ATD Part No.1215 or
equivalent
5. Refill coolant. (Refer to GROUP 14 - On-vehicle Service.)

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.
Standard value:
