DTC C0210/33 Rear Speed Sensor RH Circuit
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

DTC DETECTION CONDITION:

The speed sensor detects wheel speed and sends the appropriate signals to the skid control ECU. These signals are used for the ABS control system. This speed sensor contains a sensor IC, which consists of 2 MREs (Magnetic Resistance Element). The speed sensor rotor, which consists of 48 sets of N and S poles that are arranged in a circle, is integrated with the inner race of the hub bearing.

To detect the rotation direction, the output waves are used to determine the relationship of the pulses that are generated by 2 MREs. Upon receiving this signal, the sensor IC outputs a forward or backward wave to the ECU.

DTCs C1273/73 and C1274/74 can be deleted when the speed sensor sends a vehicle speed signal or the Test Mode ends. DTCs C1273/73 and C1274/74 are output only in the Test Mode.

HINT:
^ DTC C0210/33 is for the rear speed sensor RH.
^ DTC C0205/32 is for the rear speed sensor LH.
