  • Sensor rotor of front wheel is integrated in wheel hub assembly.
  • Wheel sensor of rear wheel is installed on rear final drive.
  • Sensor rotor of rear wheel is installed on drive shaft (rear final drive side).
  • Never measure resistance and voltage value using a tester because sensor is active sensor.
  • Power supply is supplied to detection portion so that magnetic field line is read. Magnetic field that is detected is converted to current signal.

  • When sensor rotor rotates, magnetic field changes. Magnetic field change is converted to current signals (rectangular wave) and is transmitted to ABS actuator and electric unit (control unit). Change of magnetic field is proportional to wheel speed.
