DESCRIPTION

DTC DETECTION CONDITION:

DTC DETECTION CONDITION:

The speed sensor detects wheel speed and sends the appropriate signals to the ECU. These signals are used to control the ABS control system. The front rotors have 48 serrations, respectively 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.

DTCs C1271/71 and C1272/72 can be deleted when the speed sensor sends a vehicle speed signal or the test mode ends. DTCs C1271/71 and C1272/72 are output only in the test mode.

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 right rear speed sensor.
^ DTC C0215/34 is for the left rear speed sensor.
^ The BRAKE warning light comes on when speed sensor malfunctions are detected in two or more wheels.

WIRING DIAGRAM:

NOTICE: When replacing the skid control ECU, perform initialization of linear solenoid valve and calibration.
