INSPECTION PROCEDURE

HINT:
Check the condition of each related circuit connector before troubleshooting (CAMRY_ACV40 RM000000UZ301ZX.html).
1.READ VALUE USING INTELLIGENT TESTER (REAR SPEED SENSOR)

  1. Connect the intelligent tester to the DLC3.

  1. Start the engine.

  1. Select "Data List" and read the value displayed on the intelligent tester (CAMRY_ACV40 RM000001JBA003X.html).

    Data List: ABS
    Tester Display
    		Measurement Item/Range
    		Normal Condition
    RR Wheel Speed
    		Wheel speed sensor (RR) reading / min.: 0 km/h (0 mph), max.: 326 km/h (202 mph)
    		Actual wheel speed
    RL Wheel Speed
    		Wheel speed sensor (RL) reading / min.: 0 km/h (0 mph), max.: 326 km/h (202 mph)
    		Actual wheel speed

  1. 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.

    OK:
    The speed value output from the speed sensor displayed on the intelligent tester is the same as the actual vehicle speed.

Go to step 5
OK


2.PERFORM TEST MODE INSPECTION (SIGNAL CHECK)

  1. Check if test mode (signal check) DTCs are detected (CAMRY_ACV40 RM000001JBD03HX.html).

    Result:

    Condition
    		Proceed to
    Test mode (signal check) DTC is not output
    		A

3.INSPECT SPEED SENSOR SIGNAL WAVEFORM


    Camry. Acv40 Gsv40.Brake Control.Anti-Lock Brake System. Dtc C0210/33 Right Rear Wheel Speed Sensor Signal Malfunction

  1. Lift up the vehicle.

  1. Perform the inspection using an oscilloscope.

    1. Disconnect the skid control ECU connector.

    2. Connect the oscilloscope to terminals of the skid control ECU.

    3. Check that a waveform is output when the tires are rotated.

      OK:
      The same waveform is output from rear wheels and there is no noise or interference in the waveform.
      HINT:
      1. As vehicle speed (wheel rotation speed) increases, the width of the waveform narrows and the output voltage becomes greater.
      2. When noise is identified in the waveform on the oscilloscope, the erratic signals are generated due to rotor scratches, looseness or foreign matter attached to the speed sensor.

    4. Connect the connector.

  1. Check if the same DTCs are recorded (CAMRY_ACV40 RM000001JB800PX.html).

    HINT:
    Reinstall the sensors, connectors, etc. and restore the vehicle to its prior condition before rechecking for DTCs.

    Result:

    Condition
    		Proceed to
    DTCs (C0210/33, C0215/34, C1332/38 and C1333/39) are output
