3. Turn the intelligent tester on.
   

4. Enter the following menus : Powertrain / Engine and ECT / Data List.
   

5. According to the display on intelligent tester, read the Data List.
   
   

   Reference: km/h

   Intelligent tester display	Speedometer display Data in ( ) is for reference
   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
   200 km/h	207.7 to 215.7 km/h
   220 km/h	228.4 to 236.8 km/h
   240 km/h	249.2 to 258 km/h

   
   

   Reference: mph

   Intelligent tester display	Speedometer display
   20 mph	21 to 23.5 mph
   40 mph	42 to 44.5 mph
   60 mph	62.5 to 66 mph
   80 mph	83.1 to 87.1 mph
   100 mph	103.9 to 108.4 mph
   120 mph	124.7 to 129.6 mph
   140 mph	145.4 to 150.7 mph

   CAUTION:

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

6. Check the deflection width of the speedometer indicator.
   

   Reference:

   Below 0.5 km/h (0.3 mph)
   

Check the output signal waveform.

1. Remove the combination meter, but do not disconnect the connector.
   

2. Connect an oscilloscope to terminal E22-39 and the body ground.
   

3. Start the engine.
   

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

   Item	Condition
   Tool setting	5 V/DIV, 20 ms/DIV
   Vehicle condition	Driving at approx. 20 km/h (12.4 mph)

   OK:

   Waveform is as shown in the illustration.
   

   HINT:

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

Check the operation.

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

   CAUTION:

   1. Reversing the connection of the tachometer will damage the transistors and the insides of the diodes.
      
   2. When removing or installing the tachometer, be careful not to drop or strike it.
      

2. Compare the result of the test with the standard indication.
   
   

   Reference: DC 13.5 V, at 25°C (77°F)

   Standard indication (rpm)	Acceptable range (rpm) Data in ( ) are for reference
   700	630 to 770
   1,000	(900 to 1,100)
   2,000	(1,850 to 2,150)
   3,000	2,800 to 3,200
   4,000	(3,800 to 4,200)
   5,000	4,800 to 5,200
   6,000	(5,750 to 6,250)
   7,000	6,700 to 7,300
   8,000	(7,700 to 8,300)

Disconnect the connector from the sender gauge.

Turn the ignition switch on (IG), then check the position of the receiver gauge needle.

OK:

Needle position is on EMPTY.

Connect terminals 1 and 2 on the wire harness side connector of the fuel sender gauge.

Turn the ignition switch on (IG), then check the position of the receiver gauge needle.

OK:

Needle position is on FULL.

Disconnect the connector from the sender gauge.

Turn the ignition switch on (IG), check that the fuel level needle indicates EMPTY and fuel level warning light comes on.

OK:

Fuel level warning light comes on.

Inspect the parking brake warning light.

1. Disconnect the connector from the parking brake switch.
   

2. Turn the ignition switch on (IG).
   

3. Ground the terminal of the wire harness side connector, and then check that the parking brake warning light illuminates.
   

   OK:

   Parking brake warning light illuminates.
   

Disconnect the connector from the engine oil pressure switch.

Turn the ignition switch on (IG).

Ground the terminal of the wire harness side connector, then check the engine oil pressure warning light.

OK:

Engine oil pressure warning light comes on.
