C0215

DTC C0215 Left Rear Speed Sensor




CIRCUIT DESCRIPTION
The speed sensor detects wheel speed and sends the appropriate signals to the ECU. These signals are used for control of the ABS control system. The front and rear rotors each have 48 serrations.
When the rotors rotate, the magnetic field emitted by the permanent magnet in the speed sensor generates 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.




DETECTING CONDITIONS

HINT:
DTC No. C0200/31 is for the right front speed sensor.
DTC No. C0205/32 is for the left front speed sensor.
DTC No. C0210/33 is for the right rear speed sensor.
DTC No. C0215/34 is for the left rear speed sensor.

Fail safe function:
If trouble occurs in the speed sensor circuit, the ECU cuts off current to the ABS solenoid relay and prohibits ABS control and the brake system becomes normal.
