   CHECK HARNESS AND CONNECTOR (MOMENTARY INTERRUPTION)

   
   

   1. Using the intelligent tester, check for any momentary interruption in the wire harness and connector corresponding to the DTC (Click here).

      Table 1. ABS / VSC / TRC:

      Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
      RR Speed Open	RR speed sensor open detection / ERROR or NORMAL	ERROR: Momentary interruption NORMAL: Normal	-
      RL Speed Open	RL speed sensor open detection / ERROR or NORMAL	ERROR: Momentary interruption NORMAL: Normal	-

      OK
      There are no momentary interruptions.

      Tip:

      Perform the above inspection before removing the sensor and connector.

   READ VALUE ON INTELLIGENT TESTER (REAR SPEED SENSOR)

   
   

   1. Turn the ignition switch off.

   2. Connect the intelligent tester to the DLC3.

   3. Start the engine.

   4. Select the Data List mode on the intelligent tester (Click here).

      Table 2. ABS / VSC / TRC:

      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 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 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 intelligent tester and the speed value displayed on the speedometer when driving the vehicle.

      Tip:

      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 (Click here).

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