Dash warnings
Day before yesterday start truck, ABS light is on, along with Traction Control icon. Then the Pre-Collision Assist Not Available; Service Advance Track; Hill Descent Control Fault; and Hill Start Assist Not Available windows. Taking it in to Southwest Ford Monday, meanwhile I have to change RV campsite about 30 miles. Truck is driving just fine, brakes work as usual, just have to get rid of all warning windows to access speedometer. Any ideas before I get it to dealer? Only thing I have done lately is to install the Rancho 9000XLs at all 4 corners, and that was 2 weeks ago--moved fiver once since then, no warning lights, everything worked. Will hookup tomorrow am and hope the fiver responds to tow.

I really can’t see the new Rancho shocks causing these problems but it’ll be interesting to find out if they are the cause.

It's more than likely the the two plug near the spare my dads 18 king ranch had the same issue. The dealer could not fix the problem until I told them to look at the plugs. After that he has had no more issues. Also his was doing the same thing all the lights would come on. It usually happens to his on really humid mornings. Hope this helps

I have the same problem as you, unfortunately it can’t be duplicated, and the dealer says it hasn’t stored a code. It does it about every 10 days or so, and sometimes it requires a restart for it to go away, and other times it goes away after I cycle through the warnings.
I have already checked the plugs referred to in the many threads, and added X-12 to them. Not a bit of corrosion and dry as a bone.
Fully stock 2017 F-250 Diesel Platinum...I look forward to hearing what you find out.

Won't have any problem duplicating the problem--it will be there when I drive it in. Will be sure that the SA is aware of the plug problem at the spare tire. As to the shocks, hopefully, I did not mess up a line somewhere tied into all the warnings--pretty simple to do the shocks, so don't think I caused this...

On my prior truck, those warnings would have been indicative of a failed wheel speed sensor. On the 2017+, I would start with the connections, as mentioned above, but don't rule out a bad wheel sensor.

Have you used your emergency brake at all before you started throwing codes? I had this exact issue and it was a brake position sensor that crapped out after applying the emergency brake when I did my own tire rotation. The dealer stated this is a know issue. There was also another wire that came loose and that was corrected at the same time.
Edit: the loose wire was on the wiring harness for the e-brake. The dealer also switched out the BPP sensor

Not sure if this question was for the OP, but I have never used my e-brake, but I’ll have a look. Thanks for the input.
I wish I could duplicate the problem on command, but unfortunately it is completely random, but typically only after reaching ~40 mph after just starting up the truck.

When i i stalled Timbrens on my 17 F150, i screwed up and bolted one of the Timbren clamps over an ABS sensor wire which severed it. Got all the same exact warnings the OP stated he's having. Might have pulled an ABS sensor wire loose while doing your shocks? Or could be weird coincidence that an ABS sensor went bad? The ABS sensor gives the required feedback to the computer for the advance track and HDecentC and so on. Once i spliced the ABS wires back together, all was good.
Just a suggestion on where you might want to start looking for the problem.

Be at Southwest Ford in Weatherford, TX, tomorrow. Had to tow fiver about 50 miles to new campground, found out trailer brakes also do not work on auto--manually is ok, just not working otherwise. All lights working. Have ESP on it, 56k miles, hoping it will be covered.

Took it in to SW Ford in Weatherford--man, they have their check-in down pat, very easy. Got an XL supercab 6.2 to drive, very plain after a loaded KR. But, holy chit! that 6.2 is a runner...!
Said it is a sensor in a front wheel, ESP covered, but no part til tomorrow. Will have to suffer 450 withdrawal til then...
