Abs Sensor Sealing Boot Installation (70/01/00/NAS)

ABS SENSOR SEALING BOOT INSTALLATION

TECHNICAL SERVICE BULLETIN

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.
