DTC C0200/31 Right Front Wheel Speed Sensor Signal Malfunction

DESCRIPTION

DTC Detecting Condition:

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

When the rotors rotate, the magnetic field generated by the permanent magnet in the speed sensor induces 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 skid control ECU to detect the speed of each wheel.

DTCs C1271/71, C1272/72, C1275/75 and C1276/76 are output only in the test mode (SIGNAL CHECK).

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.

INSPECTION PROCEDURE

NOTE: When replacing the ABS & TRACTION actuator assembly, perform zero point calibration. Calibration

HINT: Start the inspection from step 1 when using the intelligent tester and start from step3 when not using the intelligent tester.
