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) 

        KM/H (CANADA)

        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.) 

        MPH (U.S.)

        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 C9-1 and 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) 

        TACHOMETER

        Standard indication (r/min) Acceptable range (r/min) Data in ( ) are for reference
        700 630 - 770
        1,000 (900 - 1100)
        2,000 (1850 - 2150)
        3,000 2800 - 3200
        4,000 (3800 - 4200)
        5,000 4800 - 5200
        6,000 (5750 - 6250)
        7,000 6700 - 7300
        8,000 7700 - 8300
  4. MAINTENANCE LIQUID RESETTING PROCEDURE 

    Indicator Condition: 

    MAINTENANCE LIQUID RESETTING PROCEDURE

    State Condition Specified State
    Blinking The vehicle runs 4,500 miles after the previous setting The indicator blinks for 15 seconds after the ignition switch is on (including 3 seconds for a bulb check).
    Continuously Illuminated The vehicle runs 5,000 miles after the previous setting The indicator is continuously illuminated after the ignition switch is on.
    1. Set the display window to ODO.
    2. Turn the ignition switch off.
    3. Pressing the reset switch, turn the ignition switch to the ON position (keep pressing for at least 5 seconds.)
    4. Reset procedure is completed.

      HINT:

      • If the ignition switch is off during reset procedure, reset mode is canceled.
      • If the reset switch is pushed off during the reset procedure, reset mode is canceled and the display shows the condition prior to the reset procedure.
