2021 kw

[rdw222]

I have a 2021 kw with a x15 Cummins in it that was being driven thru a bay and the front tire hit the pole to protect the building and must have turned the truck towards the building but it busted up the dpf filter, scr and most of the sensors on top. I had it towed back to the yard and weighing the cost of my high deductible and the fact that I needed the truck to other options I went with the other option to mandate’d and sent the box off to a person that was recommended and I have heard good things about. I put the thing back together the way people on here had suggested to others and when I got the thing back put it on plugged it up and it fired right up and runs but I have no engine brakes cruise control, and my engine fan runs all the time. I took it back to the guy that did the work and sat down there for half a day but he could not figure out why it was doing this. Looking for help to get these thing working the way it should any help would be much appreciated they say hind sight is 20/20 but I wish I had just put this on my insurance!!!
