It’s in a Kenworth t680 2015. The original engine was a paccar don’t have a clue on that ser# as the Cummins was in it when I purchased it. And I believe that the ECM came from a different engine as well sorry I’m not much help here.and yes the 79597170 is what’s in the truck now

wow, that sounds like a complete clustered-Mess!

.. that enigne ser# comes back as a CM2250 engine.

-- I can also assume that the truck / engine is "Deleted"?.. other wise, THE ENTIRE EMISSIONS SYSTEMS THAT BELONGED TO THE CM2250 ENGINE NEEDS TO ALSO BE INSTALLED TO MATCH THE ENGINE TO MAKE IT LEGAL!... AND THEN REGISTERED AS A "GLIDER", AS IT IS A 2015 TRUCK with a non-compliant (2010 emissions standards) engine in it!.. .. so this tells me clearly that it is already a "deleted" truck and engine.

NEXT:;;.... A CM2250 ECM NEEDS TO BE PUT BACK ON THAT ENGINE!!!.. PERIOD!. The program needed should match the engine ser# as well. (program CL10138 in your case). This is the proper thing to do and what needs to be done to run it correctly.

-== And since it most likely needs "deleted" after, then that is easily cured by simply copying out and e-mailing the factory clean program so that it can be "de-mandated" properly instead of having some rip-off delete tuning idiot making things worse for several thousands of $$$.

WHO MADE THIS MESS BY THE WAY?/... I sure hope like h#ell that it was not a "certified" oem repair shop.. because what they did WAS ESSENTIALLY ILLEGAL (unless they put all the 2010 emissions systems on it too and registered it as a glider). it was not the best idea to use an outdated emissions engine in a 2015 truck to begin with... THEN to make it worse yet ... TO USE THE WRONG ECM!!>??q!.. What a mess!
