RE: CM2250 FAULT CODE
I have had that code many times over the 6 years I have owned this truck. It is usually just poor quality DEF fluid. Clear the code, change the DEF filter, and top the DEF tank off, the next few times you fuel. If after that if it keeps coming up Billdozer2 is right, it could be any of the things he listed, or a dirty or malfunctioning NOX sensor. They don't always through their own code when they are starting to fail.
