Rear (2WD)
•
The rear ABS wheel-speed sensor utilizes a semi-conductor element that contains an active drive circuit
(MRelement
*
). The rear sensor is installed on the rear wheel hub.
•
The rear ABS sensor rotor utilizes a magnetic encoder system that functions with magnetic rubber, and is
integrated into the wheel hub component. Therefore, if there is any malfunction of the rear ABS sensor rotor,
replace the wheel hub component.
*
: A magneto-resistive force means that an exterior magnetic field acts on the element, changing the resistance of
the element.
Caution
•
When inspecting the ABS wheel-speed sensor, do not use a tester to inspect resistance. It
impossible that the voltage from the tester could damage the semiconductor inside the ABS wheel
speed sensor. Inspect using the parameter identification (PID) data monitor of the Mazda Modular
Diagnostic System (M-MDS).
Note
•
Magnetic encoder: A plate that has positive and negative poles (marked out) in a continuous,
alternatingline.
Rear (AWD)
•
The rear ABS wheel-speed sensor is installed on the rear knuckle and the rear ABS sensor rotor is integrated
with the rear drive shaft. Therefore, if there is any malfunction on the rear ABS sensor rotor, replace the rear
drive shaft.
