Just an update for everyone... I just bought this truck a week ago and have not added any DEF to the system. The CEL came on when I was driving it home from the dealer the night I bought it.
Turns out, someone put diesel fuel in the DEF tank either at the dealership, or the previous owner- nobody seems to know who. They are having to replace the tank and the module because of this.
