   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   RR Wheel Speed	RR wheel speed sensor reading/min.: 0 km/h (0 mph), max.: 326.4 km/h (202 mph)	Actual wheel speed	Similar speed as indicated on speedometer
   RL Wheel Speed	RL wheel speed sensor reading/min.: 0 km/h (0 mph), max.: 326.4 km/h (202 mph)	Actual wheel speed	Similar speed as indicated on speedometer

5. Check that there is no difference between the speed value output from the speed sensor displayed on the Techstream and the speed value displayed on the speedometer when driving the vehicle.

   HINT: 

   Factors that affect the indicated vehicle speed include tire size, tire inflation, and tire wear. The speed indicated on the speedometer has an allowable margin of error. This can be tested using a speedometer tester (calibrated chassis dynamometer). For details about testing and the margin of error, see the reference chart. Refer to ON-VEHICLE INSPECTION .

   OK

   The speed value output from the speed sensor displayed on the Techstream is the same as the actual vehicle speed measured using a speedometer tester (calibrated chassis dynamometer).
