On-Vehicle Inspection

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

      Reference: km/h (Canada)

      20 km/h	18.9 to 22.0 km/h
      40 km/h	37.9 to 41.8 km/h
      60 km/h	57.2 to 62.0 km/h
      80 km/h	76.6 to 82.5 km/h
      100 km/h	96.8 to 102.7 km/h
      120 km/h	117.2 to 123.2 km/h
      140 km/h	137.3 to 144.5km/h
      160 km/h	157.7 to 165.9 km/h
      180 km/h	178.3 to 187.5 km/h

      Reference: mph (U.S.A.) 

      STANDARD INDICATION REFERENCE
      
      

      Standard Indication	Acceptable Range
      20 mph	19.7 to 22.6 mph
      40 mph	39.8 to 43.2 mph
      60 mph	59.9 to 64.0 mph
      80 mph	79.2 to 85.4 mph
      100 mph	101.8 to 107.0 mph

      NOTE: Do not use worn, underinflated or overinflated tires, as the speedometer reading will be inaccurate.
   2. Check the deflection width of the speed meter indicator.

      Reference: Below 0.5 km/h (0.3 mph) 

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

1. Check the output signal waveform.
   1. Remove the combination meter, but do not disconnect the connector.
   2. Connect an oscilloscope to terminal C11-21 and body ground.
   3. Start the engine.
   4. Check the signal waveform according to the condition(s) in the table below.
      ITEM CONDITION
      
      

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

      OK: As shown in the illustration. 

      HINT:

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

1. Check operation.
   1. 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.
   2. Compare the result of the test with the standard indication.

      STANDARD INDICATION REFERENCE
      
      

      Standard Indication (r/min)	Acceptable Range (r/min) Data in ( ) are for reference
      700	630 to 770
      1,000	(900 to 1,100)
      2,000	(1,850 to 2,150)
      3,000	2,850 to 3,150
      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

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

   OK: Needle position is on FULL.
