2011 cascadia detroit engine

I have a 2010 with a DD 13. My advice is to got to the dealer with it. Those Mercedes engines are temperamental and fussy and finicky and everything has to be just so. There are wiring harnesses and modules everywhere and they burn out and corrode. Even changing the fuel filters is a nightmare. I won't even touch the thing anymore or even have service done at TA.

 

DD 13 and DD 15 engines are Mercedes. They just have the Detroit label on them. They're completely different than the old 60 series Detriots diesels.

 

You need the computer program to do it. They can clear your codes at a TA and print off a list of what's faulting for you. But you really should make plans to get it to a dealer in the long run, because of all the modules and wiring harnesses. Everything talks to everything else and a bad harness or module can cause the engine to derate. Like I said, they're fussy and finicky. They're not like the older engines.
You could try disconnecting the batteries and wait like 10 minutes before re connecting them. It might change some of the codes to inactive. Maybe.

 

It can be multiple problems. Bad MCM, bad engine harness or even a 5v reference fault code can trigger other multiple fault codes in the circuit. You need to get to a dealer and have them the truck connected to diagnostic link.
