1. CHECK SPEEDOMETER

1. Check operation.

   1. Using a speedometer tester, check that the speedometer reading is within the allowable range shown in the table below. Also, check for proper operation of the odometer.

      Reference (Australia)
      Standard Indication | Allowable Range
      20 km/h | 17.5 to 21.5 km/h
      40 km/h | 38 to 42 km/h
      60 km/h | 58 to 63 km/h
      80 km/h | 78 to 84 km/h
      100 km/h | 98 to 104.5 km/h
      120 km/h | 119 to 125 km/h
      140 km/h | 141 to 146 km/h
      160 km/h | 159 to 167 km/h
      180 km/h | 179 to 188 km/h

      Reference (General)
      Standard Indication | Allowable Range
      20 km/h | 21 to 25 km/h
      40 km/h | 41.7 to 46.2 km/h
      60 km/h | 62.7 to 67.2 km/h
      80 km/h | 83.4 to 88.4 km/h
      100 km/h | 104.3 to 109.3 km/h
      120 km/h | 125.1 to 130.6 km/h
      140 km/h | 145.8 to 151.8 km/h
      160 km/h | 166.2 to 173.2 km/h
      180 km/h | 186.9 to 194.5 km/h

      NOTICE:
        Do not use worn, underinflated or overinflated tires, as the speedometer reading will be inaccurate.

   2. Check the deflection width of the speedometer indicator.

      Reference:
        Allowable range +- 0.5 km/h
      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 the waveform of the combination meter.

      Item | Content
      Tester Connection | C8-6 - C8-22
      Tool Setting | 5 V/DIV., 20 msec./DIV.
      Vehicle Condition | Vehicle running

      OK:
        Refer to the illustration.

      HINT:
      1. As vehicle speed increases, the wavelength shortens.
      2. If the result is not specified, the speedometer may have a malfunction.

3. CHECK TACHOMETER

1. Check operation.

   1. Connect a tune-up test tachometer, and start the engine.

      NOTICE:
      1. Do not reverse the connections of the tachometer. This will damage its transistors and diodes.
      2. When removing or installing the tachometer, be careful not to drop or strike it.

   2. Compare the tester tachometer values and vehicle tachometer values under the following conditions:

      1. Vehicle battery voltage is 13.5 V
      2. Ambient temperature is 25°C (77°F)

      Standard
      Standard Tachometer Indication (rpm) | Acceptable Range (rpm) Data in ( ) are for reference only
      700 | 630 to 770
      1,000 | (900 to 1100)
      2,000 | (1850 to 2150)
      3,000 | 2800 to 3200
      4,000 | (3800 to 4200)
      5,000 | 4800 to 5200

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

4. CHECK FUEL SUCTION W/ PUMP AND GAUGE TUBE ASSEMBLY

1. Disconnect the F15*1 or F13*2 pump and gauge connector.

1. Turn the ignition switch ON, and then check the position of the receiver gauge needle.

   HINT:
     *1: 1TR-FE, 2TR-FE, 1GR-FE
     *2: 1KD-FTV, 2KD-FTV

   OK:
     Fuel receiver gauge indicates E

1. Connect terminals 2 and 3 of the wire harness side connector.

1. Turn the ignition switch ON, and then check the position of the receiver gauge needle.

   OK:
     Fuel receiver gauge indicates F
   If the result is not as specified, the combination meter may have a malfunction.

5. CHECK FUEL LEVEL WARNING LIGHT

1. Disconnect the F15*1 or F13*2 pump and gauge connector.

1. Turn the ignition switch ON, and then check that the fuel receiver gauge indicates E and that the fuel level warning light turns on.

   HINT:
     *1: 1TR-FE, 2TR-FE, 1GR-FE
     *2: 1KD-FTV, 2KD-FTV

   OK:
     Fuel level warning light turns on
   If the result is not as specified, the combination meter may have a malfunction.

6. CHECK LOW OIL PRESSURE WARNING LIGHT

1. Disconnect the E4 switch connector.

1. Connect the E4-1 terminal of the wire harness side connector to the body ground.

1. Turn the ignition switch ON, and then check that the low oil pressure warning light turns on.

   OK:
     Low oil pressure warning light turns on
   If the result is not as specified, the combination meter may have a malfunction.

7. CHECK BRAKE WARNING LIGHT

1. Check the parking brake warning light.

   1. Disconnect the P2 switch connector.

   2. Connect the P2-1 terminal of the wire harness side connector to the body ground.

   3. Turn the ignition switch ON, and then check that the warning light turns on.

      OK:
        Warning light turns on.

1. Check the brake fluid level warning light.

   1. Disconnect the B2 switch connector.

   2. Connect the B2-1 and B2-2 terminal of the wire harness side connector.

   3. Turn the ignition switch ON, and then check that the warning light turns on.

      OK:
        Warning light turns on.

1. 1KD-FTV, 2KD-FTV:
   Check the vacuum pump warning light.

   1. Disconnect the B3 switch connector.

   2. Connect the B3-1 terminal of the wire harness side connector to the body ground.

   3. Turn the ignition switch ON, and then check that the warning light turns on.

      OK:
        Warning light turns on.
      If the result is not as specified, the combination meter may have a malfunction.

8. CHECK SEAT BELT WARNING LIGHT FOR PASSENGER SIDE

1. Disconnect the F11 switch connector.

1. Connect terminals 1 and 2 of the wire harness side connector.

1. Turn the ignition switch ON, and then check that the warning light blinks.

   OK:
     Seat belt warning light for passenger side blinks.
   If the result is not as specified, the accessory meter (multi-display) may have a malfunction.
