On-Vehicle Inspection

1. Using a speedometer tester, inspect the speedometer and confirm that the speedometer readings are within the acceptable range. Also check the odometer operation.

   20 mph	19 to 22 mph
   40 mph	39 to 42.5 mph
   60 mph	59.5 to 63.5 mph
   80 mph	79.5 to 84 mph
   100 mph	100 to 105 mph
   120 mph	121 to 126.5 mph

   NOTE: Tire wear and excessively high or low tire pressure affect speedometer indications.
2. Check the deflection of the speedometer indicator.

   Reference: 

   Below 0.3 mph (0.5 km/h) 

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

2. Connect an oscilloscope to terminal E13-4 and to the body ground.
3. Start the engine.
4. Check the signal waveform according to the conditions in the table below.

   Item	Contents
   Terminal Connection	SE (E13-4) and Body Ground
   Tool Setting	5 V / DIV, 20ms / DIV
   Condition	Driving at approximately 12mph (20km 1 h)

   OK: 

   As shown in  Fig 1 . 

   NOTE: As the vehicle speed increases, the cycle of the signal waveform narrows.
5. Reinstall the combination meter assembly.

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