Need a little help fellow drivers or mechanics please

I have CAT in mine and was already at CAT,.. in and out in 2 days. Now at Freightliner for OEM specific work.

I also avoid Freightliner because of my CAT. Soon as I tell them I have a CAT,.. 9 out of 10 Freightliner say they have no CAT specialist. Detroit is all they want to work on.

I get much better service and results from local places. I try to stay on top of everything to avoid having work done while out on the road. This is the first problem I have had since my inframe over a year ago. ECM and some OEM wiring harness issues. Sounds like it should be simple,.. yet truck has been down for over a week.
