ON-VEHICLE SERVICE
SPEEDOMETER CHECK
1. Adjust the pressure of the tyres to the specified level.
2. Set the vehicle onto a speedometer tester and use wheel
chocks to hold the rear wheels.
3. Pull the parking brake lever firmly.
4. To prevent the front wheel from moving from side to side,
attach tension bars to the tie-down hook, and secure
both ends to anchor plates.
5. To prevent the vehicles from starting, attach a chain or
wire to the rear towing hook, and secure the other end
of the chain or wire firmly to an unmovable body.
6. Check if the speedometer indication range is within the
standard values and if the pointer fluctuation is within
the limits.
Caution
Do not operate the clutch suddenly. Do not
increase/decrease speed rapidly while testing.
Standard values:
Vehicle speed km/hSpeedometer indication
allowable errors km/h
4037 – 45
8075 – 88
120113 – 132
160150 – 176
Limit: Pointer fluctuation
(at vehicle speeds of higher than 35 km/h) ±3 km/h
TACHOMETER CHECK
1. Insert a paper clip in the engine speed detection connector
from the harness side, and attach the engine
speedometer.
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
*1 r/min : ±150 r/min
3,000*2 r/min : +225 to –100 r/min
5,000*1 r/min : ±250 r/min
5,000*2 r/min : +325 to –125 r/min
6,000*1 r/min : ±300 r/min
7,000*2 r/min : +400 to –100 r/min
8,000*3 r/min : +400 to 0 r/min
NOTE
*1: Tachometer measurable up to 8,000 r/min
*2: Tachometer measurable up to 9,000 r/min and one measurable up to 10,000 r/min
*3: Tachometer measureble up to 10,000 r/min

– Blower Motor Assembly, Resistor and Evaporator HEATER AND MANUAL
AIR CONDITIONER55-21
BCASE COVER, EVAPORATOR REMOVAL
The evaporator, which has been installed in a factory, has
no case cover. Follow the steps below to remove that
evaporator.
1. Cut the case along the shown line to remove the cooling
and blower unit.
2. Remove the air thermo sensor from the evaporator, and
then remove the evaporator towards you, being careful
not to damage its core.
INSPECTION
BLOWER MOTOR CHECK
When battery voltage is applied between the terminals, check
that the motor operates. Also, check that there is no abnormal
noise.
RESISTOR CHECK
Use a circuit tester to measure the resistance between the
terminals as indicated below. Check that the measured value
is at the standard value.
Standard value:
Measurement terminalStandard value Ω
Between terminals 3 and 22.81 ± 10%
Between terminals 3 and 41.28 ± 10%
Between terminals 3 and 10.33 ± 10%
