Thanks for the information.
Unfortunately the newer engines made after 2007 do not have the ability to pull flash codes like the older pre emissions engines. I am sorry. I wish that was not the case. The only way to read codes to to have someone connect to the engine with Cummins onsite software.
Please reply back if you need more help or have more questions. I am happy to assist.
