        - 220 : 220 - 230
        NOTE: Tire wear and tire over or under inflation will increase 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 standard signal.
      1. While driving the vehicle at the speed of 10 km/h, check the voltage between the terminals C9-17 and C9-20 of the combination meter assy.

        Standard: Fluctuation between 10 to 14 V or less is repeated 7 times within 1 sec. 

        NOTE: Check it with the ignition switch ON and the connector connected.

        • When removing or installing the tachometer, be careful not to drop or subject it to heavy shocks.
      2. Compare the test and tachometer indications.

        DC 13.5 V, 25 °C at (77 °F)

        2,000 (1,850 - 2,150)
        3,000 2,800 - 3,200
        4,000 (3,800 - 4,200)
        5,000 4,800 - 5,200
        6,000 (5,750 - 6,250)
        7,000 6,700 - 7,300
        8,000 7,700 - 8,300
  4. INSPECT FUEL RECEIVER GAUGE 
    1. Inspect the circuit.
      1. Disconnect the connector from the sender gauge.
      2. Turn the ignition switch ON, then check the position of the receiver gauge needle.

        Needle position: EMPTY 

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

        Needle position: FULL

    1. Inspect the circuit.
      1. Disconnect the connector from the sender gauge.
      2. Turn the ignition switch ON, check the fuel level needle indicates EMPTY and fuel level warning lights light on.
  6. INSPECT WATER TEMPERATURE RECEIVER GAUGE WARNING LIGHT 
    1. Inspect the circuit.
      1. Disconnect the connector from the sender gauge.
      2. Turn the ignition switch ON, check the position of the water temperature receiver gauge needle.

        Needle position: COOL 

      3. Connect between terminals on the wire harness side connector, then check the position of the water temperature receiver gauge needle.
