SPEEDOMETER CHECK
1. Adjust the pressure of tires to the specified level. (Refer to On-vehicle Service).
CAUTION: Do not operate the clutch suddenly. Do not increase/decrease speed rapidly while testing.
2. Set the vehicle onto a speedometer tester and use wheel chocks to hold the front wheels.
3. 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.
4. 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.
5. Check if the speedometer indicator range is within the standard values.
6. If not to the standard value, inspect for proper tire size. If not correct, replace the tires with original size tires and retest. If correct, replace the
speedometer. If still not to standard value, replace the vehicle speed sensor.
