SITUATION:
REAR ABS SENSOR SIGNAL FAULT
Under certain weather conditions the rear ABS sensor can be "lifted" away from the reluctor ring, reducing sensor sensitivity and ultimately causing the
ABS system to set a fault. Water ingress or other contaminants around the sensor housing can also cause corrosion of the toothed reluctor ring, causing
signal errors.
RESOLUTION:
INSTALL NEW ABS SENSOR SEAL
A new rubber sensor seal has been developed to ensure proper protection of the rear sensors. A properly sealed sensor reduces contamination or the
tendency for the sensor to back out of the axle housing during adverse weather conditions.
