FYI - C0245 - Wheel Speed Sensor Frequency Error

[DC1263]

My ABS would sometimes pulse at slow speed while turning into parking area or my driveway especially when raining or wet surface, also had some shake when braking hard, Sometimes the ABS/Trac lights would come on sometimes not, always off after restart. Scanned C0245 - Wheel Speed Sensor Frequency Error (Frequency difference between the left and right front sensors) Pulled front rotors off and found evidence of a grab-slip-grab-slip condition on the passenger side rotor, surfaces of both rotors were mirror smooth with slight scoring, very well glazed and a nice deep color blue, typical at 112,000? figured I'd just go ahead and install new rotors, pads were at about 50% so I cleaned them up and reused them. Took a while to reset itself , Have not seen issue since new rotors, now at 115,000 issue code is gone.

Warped rotors can cause this code, as well as a sticky caliper, caliper slides or low tire.
