After the latest firmware update 1.3.5-1128 the diagnostic feature does nothing. I can't clear the codes and obviously can't read them (never could). Is anyone else having this problem? I tried to load the previous version of firmware and I still can't clear them. I can read and clear codes with my hand held scanner so I don't think that it has anything to do with the truck. Other than that and the fuel rail pressure everything else works fine.
