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) 

      SPEEDOMETER OPERATION CHECK
      
      

      Standard indication	Acceptable range
      20 km/h	17.5 - 21.5 km/h
      40 km/h	38.0 - 42.0 km/h
      60 km/h	58.0 - 63.0 km/h
      80 km/h	78.0 - 84.0 km/h
      100 km/h	98.5 - 104.5 km/h
      120 km/h	119.0 - 125.0 km/h
      140 km/h	139.0 - 146.0 km/h
      160 km/h	159.0 - 167.0 km/h

      Reference: MPH (U.S.) 

      SPEEDOMETER OPERATION CHECK
      
      

      Standard indication	Acceptable range
      20 mph	20.0 - 23.0 mph
      40 mph	40.0 - 43.5 mph
      60 mph	60.0 - 64.0 mph
      80 mph	80.0 - 84.5 mph
      100 mph	100.0 - 105.0 mph

      NOTE: Tire wear and over or under inflation will affect the indication error.
   2. Check the deflection width of the speed meter indicator.

Reference: Below 0.5 km/h (0.3 mph) 

1. Check for the signal.
   1. While driving the vehicle at the speed of 10 km/h, check the voltage between the terminal C10-36 of the combination meter assy and the body ground.

   Standard: Fluctuation between 10 to 14 V or less is repeated 7 times within 1 sec.

1. Check the 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 standard indication.
