Meter / Gauge System On-Vehicle Inspection

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

   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.
   

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	C10-6 - C10-22
   Tool Setting	5 V/DIV., 20 msec./DIV.
   Vehicle Condition	Vehicle running

   OK:

   Refer to the illustration.
   

   HINT:

   As vehicle speed increases, the wavelength shortens.

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

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 test 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)
      

   OK

   Standard Tachometer Indication (rpm)	Acceptable Range (rpm) Data in ( ) are for reference only
   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

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

Disconnect the F14*1 or F13*2 pump and gauge connector.

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

OK:
