C1105, C1106, C1107, C1108 WHEEL SENSOR

C1105, C1106, C1107, C1108 WHEEL SENSOR

Description

INFOID:0000000009479259

When the sensor rotor rotates, the magnetic field changes. It converts the magnetic field changes to current

signals (rectangular wave) and transmits them to the ABS actuator and electric unit (control unit).
