ABS (Antilock Brake System)

DTC C0200/31 Front Speed Sensor RH Circuit

DESCRIPTION

DTC Detection Condition:

The speed sensor detects wheel speed and transmits the appropriate signals to the ECU. These signals are used for control of the ABS control system. The front and rear rotors have 48 serrations each.

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 C1271/71 to C1276/76 can be deleted when the speed sensor sends a vehicle speed signal or the Test Mode ends. DTCs C1271/71 to C1276/76 are output only in the Test Mode.

HINT:
- DTC No. C0200/31 and C1235/35 are for the front speed sensor RH.
- DTC No. C0205/32 and C1236/36 are for the front speed sensor LH.
