2015 RAM 3500 - 45,000 miles.
A message popped saying, "5 MPH Max Speed in 131 mi, Service DEF System See Dealer".
I have no codes (outside of some left door panel or something other).
Hooked up OBDII and see there were 88.66 lbs of DEF Pressure so the pump is working.
I tried clearing codes, but it remains.
Any thoughts on how I can get this message cleared?
It goes without saying; I need my truck later this week.
I called the Dealership, and they said they're 3 weeks behind.
Any thoughts?
Thanks.
