The defect
The involved anti-lock wheel speed sensors may contain improperly magnetized stator assemblies. This condition could result in malfunction of the brake anti-lock system leading to an increase in vehicle stopping distances and the possibility of wheel lock-up during braking at speeds above 10 m.p.h., due to inability of the anti-lock system to properly control braking pressure.
The remedy
Field inspections will be conducted and suspect sensor stators will be replaced with properly magnetized units.
