ABS SENSOR
The ABS sensors consist of fixed ABS speed sen-
sors and the ABS rotors that rotate at the same
speed as the wheels, that output alternating current
signals at frequencies which are proportional to the
wheel speed.
•
The ABS rotors (43 teeth) are installed to the
drive shafts, and the ABS speed sensors are
installed to knuckles.
•
The gap between the ABS rotors and the ABS
speed sensors are non-adjustable at both the
front and rear to improve serviceability.
LATERAL G-SENSOR/LONGITUDINAL G-SENSOR
The longitudinal G-sensor detects the acceleration in
the lateral direction of the vehicle, and are basically
the same as those used conventionally. The lateral
G-sensor is used for detecting the acceleration along
the sides of the vehicle by changing the installing
direction by 90 degree angle. The same sensor as
the longitudinal G-sensor is used.
