2015 Freightliner cascadia evo abs

I had that with almost every trailer I hooked to at werner in a 2016 shaker. Shop "checked it" and said nothing was wrong

 

it is a violation I think. What I would do is make sure there is a paper trail showing you tried to get it fixed but company didn't. So if you get a ticket you could probably get it pinned on the company because you have proof you tried to get it fixed but they didn't

 

If it's your truck go to www.dtnaconnect.com and sign up for an account then you can have access to wiring diagram, part catalog....

 

You should have received an email from them saying you need to update the 'warranty database' for the truck. The 'warranty database' is Freightliner internal database and the truck's previous owner is probably still on file. You need to contact your local Freightliner dealer and ask them to update the truck's owner information to yours, you will need to provide proof of ownership such as title or bill of sale...

After your local dealer 'update' the truck owner info contact dtna again tell them it has been done they will give you access.
