On-Vehicle Inspection

  1. INSPECT SPEEDOMETER 
    1. Check the operation.
      1. Using a speedometer tester, inspect the speedometer for acceptable indication error and check the operation of the odometer.

        Reference: km/h (Canada) 

        SPEEDOMETER REFERENCE CHART

        Standard indication Acceptable range
        20 km/h 17.5 - 21.5 km/h
        40 km/h 38.0 - 42.0 km/h
        60 km/h 58.0 - 63.0 km/h
        80 km/h 78.0 - 84.0 km/h
        100 km/h 98.5- 104.5 km/h
        120 km/h 119.0- 125.0 km/h
        140 km/h 139.0-146.0 km/h
        160 km/h 159.0-167.0 km/h
        180 km/h 179.0-188.0 km/h
        200 km/h 199.0 - 209.0 km/h
        220 km/h 219.0-230.0 km/h

        Reference: MPH (U.S.) 

        SPEEDOMETER REFERENCE CHART

        Standard indication Acceptable range
        20 mph 20.0 - 23.0 mph
        40 mph 40.0 - 43.5 mph
        60 mph 60.0 - 64.0 mph
        80 mph 80.0 - 84.5 mph
        100 mph 100.0- 105.0 mph
        120 mph 120.0- 125.5 mph
        140 mph 140.0- 146.0 mph
        NOTE: Tire wear and over or under tire pressure will affect the indication error.
      2. Check the deflection width of the speed meter indicator.

        Reference: Below 0.5 km/h (0.3 mph) 

  2. INSPECT OUTPUT SIGNAL OF VEHICLE SPEED 
    1. Check for the signal.
      1. While driving the vehicle at 10 km/h, check the voltage between the terminal C9-1and C9-18 of the combination meter assy.

        Standard: Fluctuation between 7.7 to 14 V or less is repeated 7 times within 1 sec. 

        NOTE: Check it with the ignition switch turned to the ON position and the connector connected.
  3. INSPECT TACHOMETER 
    1. Check operation
      1. Connect the tune-up test tachometer, and start the engine.
        NOTE:
        • Reversing the connection of the tachometer will damage the transistors and the insides of the diodes.
        • When removing or installing the tachometer, be careful not to drop or subject it to heavy shocks.
      2. Compare the result of the test with the standard indication.

        DC 13.5 V, 25 °C (77 °F)
