INSPECTION OF COMPONENTS

SPEEDOMETER

1. Adjust the pressure of the tires to the specified level.
2. Drive the vehicle onto a speedometer tester. Use wheel chocks as appropriate.




3. Check if the speedometer indicator range is within the standard values in the service specifications.

CAUTION: Do not operate the clutch suddenly or increase/ decrease speed rapidly while testing.

NOTE: Tire wear and tire over or under inflation will increase the indication error

TACHOMETER

1. Connect the scan tool to the diagnostic link connector or install a tachometer.




2. With the engine started, compare the readings of the tester with that of the tachometer. Replace the tachometer it the tolerance is exceeded.

CAUTION: When removing or installing the tachometer be careful not to drop it or subject it to severe shock.
