Multiple emissions codes and probably wrong calibration.

I finally managed to get her home. Longest day I've had in a while. I don't have a lot of options in this town. Either cummins or the one independent shop. Im lost myself as to how to find the problem.
I've tried working through the troubleshooting tree. This is the first time the codes stayed active long enough to fully derate it. Usually it will only say derate for a minute or two, everyday or every other day. Maybe now an experienced person will be able to chase it down.
