      220 km/h	219 to 230 km/h

      NOTE: Tire wear as well as over or under inflation will cause errors.
   2. Check the deviation from the acceptable range.

      Reference: Less than 0.5 km/h (0.3 mph) 

      HINT:

      If the indication is not as specified, go to problem symptoms table (see PROBLEM SYMPTOMS TABLE ).

1. Check the input signal waveform.
   1. Remove the combination meter with connectors still connected.
   2. Connect the oscilloscope to the terminal C9-10 and the body ground.
   3. Start the engine.

   4. Check the signal waveform according to the condition(s) in the table below.
      ITEM CONDITION CHART
      
      

      Item	Condition
      Tool setting	5 V/DIV, 20 ms/DIV.
      Vehicle condition	Driving at approx. 20 km/h (12 mph)

      OK: As shown in the illustration 

      HINT:

      As vehicle speed increases, the cycle of the signal waveform narrows.

1. Check the operation
   1. Connect a tune-up tachometer, and start the engine.
   2. Compare the test results with the tachometer indications.

      HINT:

      If the indication is not as specified, go to problem symptoms table (see PROBLEM SYMPTOMS TABLE ).

1. Disconnect the connector from the sender gauge.
2. Turn the ignition switch ON, then check the position of the receiver gauge needle.

   OK: Needle position is on EMPTY. 

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

   OK: Needle position is on FULL. 

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 up.

   OK: Fuel level warning light comes on.

1. Disconnect the connector from the sender gauge.
2. Turn the ignition switch ON, check the position of the water temperature receiver gauge needle.

   OK: Needle position is on COOL. 

1. Disconnect the connector from the low oil pressure switch.
2. Turn the ignition switch ON.
3. Connect the terminal of wire harness side connector and ground, then check the warning low oil pressure warning light.

   OK: Low oil pressure warning light comes on. 

1. Inspect the parking brake warning light.
   1. Disconnect the connector from the parking brake switch.
   2. Turn the ignition switch ON.
   3. Ground the terminal of the wire harness side connector, then check the parking brake warning light.

      OK: Brake warning light comes on. 

2. Inspect the brake fluid level warning light.
   1. Disconnect the connector from the brake fluid level warning switch.
   2. Turn the ignition switch ON.
   3. Connect a terminal to the other terminal of the wire harness side connector, then check the brake fluid level warning switch.

      OK: Brake warning light comes on. 

1. Remove the reservoir tank cap and strainer.
2. Disconnect the connector.
3. Measure the resistance between the terminals.

   Standard resistance: 

   Float up (switch off): 10 kΩ or higher 

4. Use a syphon, etc. to take fluid out of the reservoir tank.
5. Measure the resistance between the terminals.

   Standard resistance: 

   Float down (switch on): Below 1 Ω 

6. Pour the fluid back in the reservoir tank.

Indicator Condition 

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