I was towing a 7000 pound RV in my new 2017 F-150. After pulling out of a rest stop,500 miles into our trip, and only 1991 miles on truck, got these 4 messages on the dash:
Steering assist fault service required
Hill Start assist not available
Service advance trac
Hill descent control fault
Has hard steering, pulls to left and right at different times
Called Femont Ford dealership in Fremont, MI, went in for diagnosis. They retrieved codes C0051:64 from PCSM and ABS modules. Cleared codes, test drove it, found no further issues. Sent me on my way.
Two hours later, hooked up RV, left campground, and within 1 mile, came to a stop, made a right turn, began accelerating and got 2 of the messages again.
Steering assist fault service required
Hill Start assist not available
Went to KRAPOHL's Ford dealership in Mt. Pleasant, MI. They were familiar with the issue. Diagnosed the problem. They got the same code, plus one more: u0415:00. Then performed interactive pinpoint test A for EPAS. A1-22 results is replace EPAS module RVC: RPXHVNE8T87AY.
They said it would take 2 days to order it, but, safe to drive. I will get this done at a 3rd dealership next week.
