Detroit 60 issues

@QUALITYTRUCK

 

Kind of hard to get full story with video. Want to verify couple of things. (1) early in video "ECU 128" displayed in message center. Check engine light usually on with that message. Is CEL burnt out on dash? Has it been plugged in with DDDL yet? (2) later on in video is RPM fluctuating like that by itself or are you on pedal reving?

 

Don't know what "That code means there is a code but FL says there's not really a code" really means. In order to help narrow down an issue you are going to have to go somewhere that is proficient with DDDL. Too many possibilities with the info. that you have given. Why a FL dealer is having an issue with this is beyond me.

 

You could take it to a Detroit Diesel shop or if you ever go to Pennsylvania Pittsburgh Power claim they can fix truck other can’t.

One of the problems they had when DPF was first put on trucks. The DPF filter was clogging from my understanding. What we know now the S60 engine and all those engines at that time, were not running hot enough to keep the DPF hot when driving down the road and keep them clean.

One of the reasons the newer engines run hotter today is to keep the exhaust hotter and keep the DPF working when driving and not needing a parked regen.

I’m just guess that could be your problem because you said truck if fine after dealer does parked regen it good for a couple days. Pittsburgh Power sells additive to help diesel run hotter. It really for the newer truck not sure if it can get S60 exhaust hot enough to keep DPF filter clean or not

Pittsburg Power might have a better ecm tune to help those first generation DPF trucks

 

Is this a DDEC6 Engine ?
