Instrument Cluster: Inspection: 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.
    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.
