ABS W/EBD System

DTC C0210/33 RIGHT REAR SPEED SENSOR CIRCUIT

CIRCUIT 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 C1273/73, C1274/74, C1277/77 and C1278/78 are output only in the test mode (SIGNAL CHECK).

HINT:
DTC No. C0210/33 and C1238/38 are for the right rear speed sensor.
DTC No. C0215/34 and C1239/39 are for the left rear speed sensor.
