DTC C0215/34 Rear Speed Sensor LH Circuit

DTC C1273/73 Low Output Signal of Rear Speed Sensor RH (Test Mode DTC)

DTC C1274/74 Low Output Signal of Rear Speed Sensor LH (Test Mode DTC)


DESCRIPTION

The speed sensors detect wheel speed and transmit the signals to the ECU. These signals are used for control of the ABS control system. Each of the front and rear rotors have 48 serrations.
When the rotors rotate, the magnetic field generated by the permanent magnet in the speed sensor induces an AC voltage.
Since the frequency of this AC voltage changes in direct proportion to the speed of the rotor, the frequency is used by the ECU to detect the speed of each wheel.
DTCs C1273/73 and C1274/74 can be deleted when the speed sensor sends a wheel speed signal or the Test Mode ends. DTCs C1273/73 and C1274/74 are output only in the Test Mode.

9.CHECK SPEED SENSOR AND SPEED SENSOR ROTOR SERRATIONS


    Camry. Acv40 Gsv40.Brake Control.Anti-Lock Brake System. Dtc C0210/33 Rear Speed Sensor Rh Circuit

  1. Reconnect the skid control sensor wire.

  1. Reconnect the the rear speed sensor connector.

  1. Connect the oscilloscope to the rear speed sensor terminal of the skid control ECU.

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

    OK:
    The same waveform is output from all the 4 wheels and there is no noise or interference in the waveform.
    HINT:
    1. As the vehicle speed (wheel revolution speed) increases, a cycle 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 speed sensor rotor's scratches, looseness or foreign matter attached to it.
