  2. When the momentary interruption of each vehicle speed sensor signal has been occurred more than 7 times.

  3. When open circuit condition of the vehicle speed sensor signal circuit has been continued for more than 0.5 seconds.

  • Right front and left front speed sensor

  • Each speed sensor circuit

  • Speed sensor rotor

  • Sensor installation

INSPECTION PROCEDURE

Tech Tips

Start the inspection from step 1 in case of using intelligent tester and start from step 2 in case of not using intelligent tester.

PROCEDURE


  1. READ VALUE OF REAR SPEED SENSOR


    1. Select the DATALIST mode on the intelligent tester.

    2. Check that there is no difference between the speed value output from the speed sensor displayed by the intelligent tester and the speed value displayed by the speedometer when driving the vehicle.

      OK
      There is almost no difference from the displayed speed value.

      Tech Tips

      There is tolerance of +/- 10% in the speedometer indication.


    OK

  5. INSPECT SPEED SENSOR AND SENSOR ROTOR SERRATIONS INSTALLATION

    A01KEFIE01

    (REFERENCE) INSPECTION USING OSCILLOSCOPE


    1. Connect the oscilloscope to the terminals RR+, RR- and and GND of the skid control ECU.

    2. Drive the vehicle at about 30 km/h (19 mph), and check the signal waveform.

      Tech Tips


      • As the vehicle speed (wheel revolution speed) increases, a cycle of the waveform becomes shorter and the fluctuation in the output voltage becomes greater.

      • When noise is identified in the waveform on the oscilloscope, error signals are generated due to the speed sensor rotor's scratches, looseness or foreign matter deposited on it.


    OK

    CHECK AND REPLACE SKID CONTROL ECU ASSEMBLY

    NG

  6. INSPECT SPEED SENSOR ROTOR AND SENSOR TIP


    1. Remove the rear speed sensor Click here.

    2. Check the sensor tip.

      *B Single Tire Type

    2. Check the sensor rotor serrations

      OK
      No scratches, missing teeth or foreign objects.

      Tech Tips

      If foreign matter is attached, remove it and after reassembling, check the output waveform.
