2014 6.7 Aftertreatment Regen Failure to Complete

[Bruce Amacker]

Here's a new truck, a 2014 with under 200 miles:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Why did it boot out- did the DOC overheat?

 

Why does the DIST REGEN C not read correctly?

 

Why do 6.4s have Regen Request and 6.7s don't?

 

Thanks!

Did it prompt you that a manual regen was not needed and do you want to continue anyways? 

[Bruce Amacker]

Yes, it did, but in the past I've always been able to complete a regen.  I'm more concerned about the DOC temp- pushing 1400F seems too high to me. You guys are probably only regenning trucks that are plugged, most of the time I'm regenning trucks that are not plugged.

I mentioned in another topic that I had a 6.7L time out too son on for no explainable reason - the DPF was loaded. On my second try it timed out again and I just left the truck alone. 15 minutes later id throttled down and completed the regen. I rechecked the DPF state and it showed clean.
