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).
