On-Vehicle Inspection

  1. CHECK SPEEDOMETER 
    1. Check the operation.
      1. Using a speedometer tester, check the speedometer for the allowable indication error and proper operation of the odometer.

        USA (mph): 

        SPEEDOMETER - USA

        Standard Indication Allowable Range
        20 mph 18 to 24 mph
        40 mph 38 to 44 mph
        60 mph 56 to 66 mph
        80 mph 78 to 88 mph
        100 mph 98 to 110 mph
        120 mph 118 to 132 mph

        CANADA (km/h): 

        SPEEDOMETER - CANADA

        Standard Indication Allowable Range
        20 km/h 17 to 24 km/h
        40 km/h 38 to 46 km/h
        60 km/h 57.5 to 67 km/h
        80 km/h 77 to 88 km/h
        100 km/h 96 to 109 km/h
        120 km/h 115 to 130 km/h
        140 km/h 134 to 151.5 km/h
        160 km/h 153 to 173 km/h
        NOTE: Worn, under inflated or overinflated tires will increases the error margin of the speedometer.
      2. Check the deflection width of the speedometer indicator.

        Reference: Allowable range +/- 0.5 km/h (0.3 mph) 

        If the result is not as specified, the speedometer may have a malfunction.

  2. CHECK OUTPUT SIGNAL OF VEHICLE SPEED 
    1. Check the output signal waveform.
      1. Remove the combination meter, but do not disconnect the connector.
      2. Using an oscilloscope, check signal waveform of the combination meter.
        OUTPUT SIGNAL OF VEHICLE SPEED

        Tester Connection Tool Setting Vehicle Condition
        C8-19 (S1) - Body ground 5 V/DIV, 20 msec./DIV Vehicle running

        OK: As shown in  Fig 1 

        HINT:

        As vehicle speed increases, the wave length shortens.

        If the result is not as specified, the speedometer may have a malfunction.

  3. CHECK TACHOMETER 
    1. Check the operation
      1. Connect a tune-up test tachometer, and start the engine.
        NOTE:
        • Do not reverse the connections of the tachometer. This will damage its transistors and diodes.
        • When removing or installing the tachometer, be careful not to drop or strike it.
      2. Compare the test tachometer values with the vehicle tachometer values.

        DC 13.5 V, at 25°C (77°F) 

        TACHOMETER

        Standard Indication (r/min) Allowable Range (r/min) Data in ( ) are for reference
        700 617 to 757
        1,000 (882 to 1,081)
        2,000 (1,837 to 2,087)
        3,000 2,793 to 3,093
        4,000 (3,775 to 4,075)
        5,000 (4,756 to 5,056)
        6,000 (5,707 to 6,067)
  4. CHECK FUEL RECEIVER GAUGE 
    1. Disconnect the F15 sender gauge connector.
    2. Turn the ignition switch ON, and then check the position of the receiver gauge needle.

      OK: Fuel receiver gauge indicates E 

    3. Connect terminals 2 and 3 on the wire harness side connector.
    4. Turn the ignition switch ON, and then check the position of the receiver gauge needle.

      OK: Fuel receiver gauge indicates F

  5. CHECK FUEL LEVEL WARNING LAMP 
    1. Disconnect the F15 sender gauge connector.
    2. Turn the ignition switch ON, and then check the fuel receiver gauge position and fuel level warning lamp.

      OK: Fuel level receiver gauge indicates E and fuel level warning lamp illuminates. 

  6. CHECK ENGINE COOLANT TEMPERATURE RECEIVER GAUGE 
    1. Disconnect the C8 meter connector.
    2. Turn the ignition switch ON, and then check the position of the engine coolant temperature receiver gauge.

      OK: Engine coolant temperature receiver gauge indicates C 

    3. Connect terminal 2 on the wire harness side connector to the body ground.
    4. Turn the ignition switch ON, and then check the position of the engine coolant temperature receiver gauge needle.

      OK: Engine coolant temperature receiver gauge indicates H 

  7. CHECK LOW OIL PRESSURE WARNING LAMP 
    1. Disconnect the O2 switch connector.
    2. Connect the terminal O2-1 of wire harness side connector to the body ground.
    3. Turn the ignition switch ON, and then check the low oil pressure warning lamp.
