On-Vehicle Inspection

1. Check the operation.
2. Using a speedometer tester, inspect the speedometer for acceptable indication error and check the operation of the odometer.

   REFERENCE: MPH (U.S.A) 

   SPEEDOMETER ACCEPTABLE INDICATION
   
   

   Standard indication	Acceptable range
   20 mph	18.5 to 21.5 mph
   40 mph	38.5 to 41.5 mph
   60 mph	59.0 to 62.5 mph
   80 mph	79.0 to 83.0 mph
   100 mph	99.0 to 104.0 mph
   120 mph	119.0 to 125.0 mph

   NOTE: Tire wear and over or under tire pressure will affect indication error.
3. Check the deflection width of the speedometer indicator.

Reference: Below 0.5 km/h (0.3 mph) 

1. Check the output signal waveform.

1. Remove the combination meter assy.
2. Connect the oscilloscope to terminal C12-19 and body ground.
3. Start the engine.

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

OK: 

As shown in the illustration 

HINT:

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

1. Check operation
2. Connect the tune-up test tachometer and start the engine.
   NOTE:

   • Reversing the connection of the tachometer will damage the transistors and the insides of the diodes.
   • When removing or installing the tachometer, be careful not to drop or subject it to heavy shocks.
3. Compare the result of the test with the standard indication.

1. Disconnect the connector from the sender gauge.
2. Connect terminals 1 and 2 on the wire harness side connector of the fuel sender gauge.
3. Turn the ignition switch to the ON position, then check the position of the receiver gauge needle.

   OK: 

   Needle position is on (EMPTY). 

4. Connect terminals 2 and 3 on the wire harness side connector of the fuel sender gauge.
5. Turn the ignition switch to the ON position, 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 to the ON position, then check that the fuel level needle indicates EMPTY and the fuel level warning light comes on.

OK: 

Fuel level warning light comes on. 

1. Disconnect the connector from the low oil pressure switch.
2. Turn the ignition switch to the ON position.
3. Ground the terminal of the wire harness side connector, then check the 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 to the ON position.
   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 to the ON position.
   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: 

   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: 

   Float down (switch on): Below 1 Ω 

6. Pour the fluid back in the reservoir tank.

1. Disconnect the connector from the washer level warning switch.
2. Turn the ignition switch to the ON position.
3. Ground the terminal of the wire harness side connector, then check the washer level warning light.

OK: 

Washer level warning light comes on. 

1. Check that the display for ODO/TRIP shows no value (BLANK).
2. Turn the ignition switch off.
3. Pressing the reset switch, turn the ignition switch to the ON (keep pressing at least for 5 seconds).
4. The reset procedure is completed.

HINT:

• During reset procedure:

  "Mileage Reset" is displayed and the master warning light comes on with a buzzer sound.

• Completion of reset procedure:

  "Mileage Reset" and the master warning light go off.

• If the ignition switch is turned off during reset procedure, reset mode is canceled.
• If the reset switch is turned off during the reset procedure, reset mode is canceled and the display shows the condition prior to the reset procedure.
• If "Maint Reqd Soon" is displayed, it goes off 15 seconds after turning the ignition switch to the ON position.
