On-Vehicle Inspection

1. Using a speedometer tester (calibrated chassis dynamometer), inspect the speedometer and confirm that the speedometer readings are within the acceptable range.

   Reference: mph 

   SPEEDOMETER READINGS
   
   

   Standard indication	Acceptable range
   20 mph	18 0 to 21 0 mph
   40 mph	38 5 to 42.0 mph
   60 mph	59 0 to 63 0 mph
   80 mph	79.5 to 84.0 mph
   100 mph	100.0 to 105 0 mph
   120 mph	121.0 to 126.5 mph

   Reference: km/h 

   STANDARD INDICATION
   
   

   Standard indication	Acceptable 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

   CAUTION: Tire wear and excessively high or low tire pressure affect speedometer indications.
2. Check the width of the speedometer needle deflection.

   Reference: 

   Below 0.3 degrees. 

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

2. Start the engine.
3. Check the signal waveform according to the condition(s) in the table below.
   OUTPUT SIGNAL OF VEHICLE SPEED SENSOR
   
   

   Item	Condition
   Terminal connection	F1-17 (+S) - Body ground
   Tool setting	5 V/DIV, 20 msec/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.

1. Connect a Techstream to the DLC3.
2. Start the engine.
3. Operate the Techstream according to the display and select "Data List" (See DATA LIST / ACTIVE TEST  ).

   Body Electrical / Combination Meter / Data List: 

   BODY ELECTRICAL / COMBINATION METER / DATA LIST
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Engine RPM	Engine speed Min.: 0 Max.: 12,750	Approximately same as actual engine speed	Unit: rpm

4. Compare the engine speed displayed on the tester with the tachometer reading.

   Reference 

   RANGE (RPM) DATA
   
   

   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
