ABS COMPONENT FUNCTIONS
Wheel sensors and wheel sensor rotors
Wheel sensors “1” detect the wheel rotation speed and transmit the wheel rotation signal to the ABS
ECU.
Each wheel sensor contains a Hall IC. The wheel sensors are installed in the sensor housing for each
wheel.
Sensor rotors “2” are installed on the inner side of the front and rear wheel hubs and rotate with the
wheels.
