C1101, C1102, C1103, C1104 WHEEL SENSOR

VDC/TCS/ABS

C1101 C1102 C1103 C1104

Description


When the sensor rotor rotates, the magnetic field changes. The sensor rotor converts the changes in the magnetic field to current signals (rectangular wave), and transmits them to the ABS actuator and electric unit (control unit).
