Mine failed at one point as well. I haven't attempted to fix it by any means, but it looks difficult. I don't know why I didn't think of it early, but Ag Express would be a company with the potential to fix it more than anyone else I know of. I do know, when the new module was installed, it was a newer "version", and there were a few glitches. To eliminate these, the dealer needed to update other software on the combine, including within CEBIS. That was the best thing out of the whole deal, as it gave CEBIS a great new look, with more info and a better layout, like a newer combine would have.
