Tone Ring

Any 20-21 bounder owners have a problem with tone rings

  • Our 2021 Newmar on a 2020 F53 chassis, had what I thought was this problem very early on.   However, took it to Ford dealer, they did a reprogram/update that Ford had come out with, and never have had the problem since (that was 3 years ago).

      Thanks for the information.  I have a 2020 F53 chassis on my 2021 Fleetwood Flair with this exact problem.  Hard to diagnose if you don't know about the Tone Ring. I replaced the Wheel Speed Sensor first.  Not the problem.  Tone Ring!....never even knew it existed. Defective Tone Ring shuts down ABS, Traction Control, Hill Assist, and Cruise Control at the same time.
