You may want to take this unit to a Cummins shop as it should still be under base warranty. Cummins software is not cheep around $950.00 but some of the generic units may be found for less but you wont have the code info that you will from Cummins.

I have several of these in my fleet,I have found out that when cleaning you to remove the intake all the way to the intake heater grid,vacuum out and brush all the carbon you possible can get get out,then blow out the intake heater grid area,then test drive 10-15 miles cut bus off restart light will go out if there is not a sensor problem or plugged DPF filter.If the DPF filter is plugged you will have to have it cleaned by a repair center that has a cleaner or replace the filter.
