ON-VEHICLE SERVICE
SPEEDOMETER CHECKM1543000900423
Adjust the pressure of tyres to the specified level.
(Refer to GROUP 31, On-vehicle Service P.31-7.)
CAUTION
Do not operate the clutch suddenly. Do not
increase/decrease speed rapidly while testing.
1. Set the vehicle onto a speedometer tester and
use wheel chocks to hold the rear wheels.2. 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.
3. To prevent the vehicle from moving, attach a chain
or wire to the rear retraction hook, and make sure
the end of the chain or wire is secured.
4. Check if the speedometer indicator range is within
the standard values.
Standard value:
5. If not to the standard value, inspect for proper tyre
size. If not correct, replace the tyres with original
size tyres and retest. If correct, replace the
speedometer. If still not to standard value, replace
the vehicle speed sensor.
TACHOMETER CHECKM1543001000434
1. Attach an external high quality tachometer to the
engine speed detection connector on the harness
side (such as with a paper clip).

NOTE: For tachometer check, use an external
high quality inductive tachometer.
2. Compare the readings of the vehicle tachometer
and the external tachometer at every engine
speed, and check if the variations are within the
standard values.
Standard values:
FUEL TANK GAUGE UNIT CHECKM1543001200461
Remove the fuel tank gauge unit. (Refer to GROUP
13C, Fuel Tank P.13C-4.)
FUEL TANK GAUGE UNIT RESISTANCE
1. Check that resistance value between the fuel
gauge terminal and earth terminal is at the
standard value when the fuel tank gauge unit float
is between position "F" (highest) and position "E"
(lowest).
Standard values:
2. Check that resistance value changes smoothly
when the float moves slowly between position "F"
(highest) and position "E" (lowest).
3. If all checks are correct, go to fuel tank gauge unit
float height check. If any check is not correct,
replace the fuel tank gauge unit.
FUEL TANK GAUGE UNIT FLOAT HEIGHT
1. Move the float and measure height A at position
"F" (highest) and B at position "E" (lowest) with
the float arm touching stopper.
Standard values:
2. If all checks are correct, go to fuel tank gauge unit
float height check. If any check is not correct,
replace the fuel tank gauge unit.
