INSPECTION OF COMPONENTS
SPEEDOMETER
  1. Using a scan-tool, inspect the speedometer for tolerance and check for the operation of the odometer.

    NOTE
    It should be noted that the excessive tire wear and tire over or under-inflation will cause indication errors.
  1. Check the speedometer for pointer fluctuation and abnormal noise.

    NOTE
    Pointer fluctuations can be caused by a faulty reed switch.
VEHICLE SPEED SENSOR
  1. Disconnect the speed sensor connect and remove the speed sensor.

  1. Connect the positive (+) lead from battery to terminal 3 and the negative (-) lead to terminal 2.

  1. Connect the positive (+) lead from tester to terminal I and the negative (-) lead to terminal 2.

  1. Turn the speed meter shaft.

  1. Check if there is voltage change from about 0V to 11V or more between terminal 1 and 2.

  1. The voltage change should be 4 times per each revolution of the shaft.

TACHOMETER
  1. Connect the Scan-tool to the diagnosis connector in the fuse box and install the tachometer.

  1. With engine started, compare the readings of the tester with that of the tachometer. Replace tachometer if tolerance is excessive.

FUEL GAUGE
Operation check
  1. Disconnect the fuel sender connector from fuel sender.

  1. Connect terminals 1 and 6 on the wire harness side connector through a 3.4 watt, 12V test bulb.

  1. Turn the ignition switch to the ON, and then check that the bulb lights up and fuel gauge needle moves to full.

Resistance check
  1. Remove the instrument cluster.

  1. Measure the resistance between terminals. (I01-1:13, I01- 2:11 )

Standard resistance

Fuel level F: Approx. 7OHM

Fuel level 1/2: Approx. 32.5OHM

Fuel level E: Approx. 95OHM

FUEL SENDER
  1. Using a ohmmeter, measure the resistance between terminals 1 and 6 at each float level.

    Float position
    F
    1/2
    E
    Resistance OHM
    3 1
    32.5 2
    110 +1 -4
  1. Also check that the resistance changes smoothly when the float moves from "E" to "F".

LOW FUEL LEVEL SENSOR
  1. Connect the sender with a test lamp (12V, 3.4W) to the battery and immerse it in the water.

  1. The lamp should be off while thermistor is submerged in the water and should illuminate when the sender is taken out of the water.

    NOTE
    If there is a malfunction, replace the fuel sender as an assembly.
    CAUTION
    After completing this test, dry the sender and install in the fuel tank.
ENGINE COOLANT TEMPERATURE GAUGE
  1. Disconnect the wiring connector from the engine coolant temperature sender in the engine compartment.

  1. Turn the ignition switch ON. Check the gauge's needle indicates cool and turn the ignition switch OFF.

  1. Ground to the harness side connector via the 12V, 3.4 watt test bulb.

  1. Turn the ignition switch ON.

  1. Check to be sure that test bulb flashes and that the indicator moves to HOT,

If operation is not as specified, replace the sender. Then recheck the system.

ENGINE COOLANT TEMPERATURE SENSOR
  1. Using an ohmmeter, measure the resistance between the terminal and ground.

  1. If the resistance value is not as shown in the below table, replace the temperature sender.

OIL PRESSURE SWITCH
  1. Check continuity between terminal and ground when engine stopped.

  1. Check no continuity between terminal and ground when the engine running.

  1. If operation is not as specified, replace the switch.

OIL PRESSURE WARNING LAMP
  1. Disconnect the connector from the warning switch and ground terminal ON the wire harness side connector.

  1. Turn the ignition switch ON, check that the warning lamp lights on. If the warning lamp doesn't light, test the bulb or inspect wire harness.

BRAKE FLUID LEVEL WARNING SWITCH
  1. Remove the connector from the switch in the brake fluid reservoir.

  1. Ensure that the continuity exists between switch terminals 1 and 2 while pressing down the switch (float) with a rod.

BRAKE FLUID LEVEL WARNING LAMP
  1. Start the engine.

  1. Release the parking brake.

  1. Release the connector from the brake fluid level warning switch.

  1. Ground the connector at the harness side.

  1. Ensure that the warning lamp lights.

PARKING BRAKE SWITCH

The parking brake switch is a push type and located under the parking brake lever. To adjust, move the switch mount up and down with the parking brake lever released all the way.

  1. Check continuity between terminal and switch body with the switch ON (Lever is pulled).

  1. Check no continuity between terminal and switch body with the switch OFF (Lever is released).

If continuity is not as specified, replace the switch or inspect ground point.

DOOR SWITCH

Remove the door switch and check continuity between the terminals.

SEAT BELT SWITCH
  1. Remove the connector from the switch.

  1. Check continuity between terminals.
