ON-VEHICLE SERVICE

SPEEDOMETER CHECK

1.

Adjust the pressure of the tyres to the specified level.
(Refer to GROUP 31 – Service Specifications.)

2.

Set the vehicle onto a speedometer tester.

3.

Use wheel chocks to hold the front wheels, and apply
the parking brake firmly.

4.

To prevent the front wheels from moving from side to
side, attach tension bars to the tie-down hooks, and secure
both ends to anchor plates.

5.

To prevent the vehicle from launching, attach a chain or
wire to the rear retraction hook, and make sure the end
of the chain or wire is secured firmly.

6.

Check if the speedometer indicator range is within the
standard values.

Caution
Do not operate the clutch suddenly. Do not
increase/decrease speed rapidly while testing.

Standard values:

Standard indication km/h

TACHOMETER CHECK

1.

Insert a paper clip in the engine speed detection connector
from the harness side, and attach the engine speedometer.

NOTE
For tachometer check, use of a fluxmeter-type engine
speedometer is recommended. (Because a fluxmeter only
needs to be clipped to the high tension cable.)

2.

Compare the readings of the engine speedometer and the
tachometer at every engine speed, and check if the
variations are within the standard values.

Standard values:

700 r/min: 

±

100 r/min

3,000 r/min: +150 r/min

–100 r/min

5,000 r/min: +325 r/min

FUEL GAUGE UNIT CHECK

Remove the fuel gauge unit from the fuel tank.
(Refer to GROUP 13C.)

FUEL GAUGE UNIT RESISTANCE

1.

Check that resistance value between the fuel gauge
terminal and earth terminal is at standard value when
fuel gauge unit float is at point F (highest) and point E
(lowest).

Standard value:

Items

Standard value 

Main

Float point F

1 –3

Float point E

49.7 – 51.7

Sub

Float point F

1 – 3

Float point E

55.3 – 57.3

2.

Check that resistance value changes smoothly when float
moves slowly between point F (highest) and point E
(lowest).

FUEL GAUGE UNIT FLOAT HEIGHT

1.

Move float and measure the height A at point F (highest)
and B at point E (lowest) with float arm touching stopper.

Standard value:

Items

Standard value mm

Main

Float point F

44.5 – 52.5

Float point E

220.3 – 228.3

Sub

Float point F

30.4 – 36.4

Float point E

238.5 – 244.5

2.

Check that resistance value changes smoothly when float
moves slowly between point F (highest) and point E
(lowest).

FUEL LEVEL SENSOR (THERMISTOR)

1.

Connect the battery to the main fuel gauge unit connector
via test lamp (12 V – 3.4 W) as shown in the illustration.

2.

Condition is good if the test lamp goes off when the
thermistor is immersed in water and comes on when it
is taken out of water.

Caution
After finishing this test, wipe the unit dry and install
it in the fuel tank.

FUEL LEVEL WARNING SWITCH CHECK

1.

Remove the sub fuel gauge unit pipe assembly. (Refer
to GROUP 13B – Fuel Tank.)

NOTE
Moving up and down of the float makes the reed switch
of fuel level warning switch turned on and off.

2.

Check the continuity between the terminals.

ENGINE COOLANT TEMPERATURE GAUGE UNIT
CHECK

1.

Bleed the engine coolant. (Refer to GROUP 14 –
On-vehicle Service.)

2.

Remove the engine coolant temperature gauge unit.

3.

Immerse the unit in 70

_

C water to measure the resistance.

Standard value: 104 

±

13.5 

4.

After checking, apply the specified adhesive around the
thread of engine coolant temperature gauge unit.

Specified sealant:

3M Adhesive Nut Locking No. 4171 or equivalent

5.

Add engine coolant. (Refer to GROUP 14 – On-vehicle
Service.)

INSPECTION

VEHICLE SPEED SENSOR INSPECTION

1.

Lift up the vehicle.

2.

Remove the vehicle speed sensor, and then connect the
vehicle speed sensor and a resistance (3 – 10 k

) as

shown in the illustration.

3.

Use a circuit tester to check that the voltage between
terminal 2 and terminal 3 changes when turning a shaft
of the vehicle speed sensor (4 pulses per each one turn).
