So I did tow my Bronco on a dolly behind my Motor Home. Let me tell you this story, there no information anywhere that I could find about towing a bronco other than a flat tow. I called Ford Tech service and they have no information either.
So I hooked it up to the dolly, strapped it down and placed it in neutral tow mode. I rolled fine and the first trip was about 2 hours or 90 miles. Once at my destination I proceeded to remove the Bronco and put it back down on the ground. I opened the door to get in and the dashboard was indicating almost 6 faults. 1. Your ABS has failed, 2. Parking Brake failure, 3. track control failure, 4. hill assist failure. and 2 more I can't remember. All of the failures were indicating to press OK, that did nothing. So after I calmed down I took it out of Neutral tow and it back off the dolly. I tried several tricks to clear the faults but nothing worked. My only thought was to get in it and drive it to the nearest dealer. Got in it and drove it about 1/4 miles and all the faults cleared themselves and it was back to normal.
This did also happened again when I towed it home on the dolly, but again the faults cleared themselves after about a 1/4 of a mile.
The only thing I can think of is the computer gets scrambled when the rear wheels are turning and the fronts are not. Once you drive it the computer clears itself. anyone else seen or heard of this?
