Dealing with a 6255 code and i can’t get it to go inactive. Believe that code was caused by 3151 or 3749. Replaced outlet nox sensor and both of those went inactive. Also had a def line leaking at the injector so I replaced that.

I’ve put the truck into regen I’ve drove it I’ve tried to clear the 6255 code but I cannot get it to go inactive. I’ve read maybe you need to reflash the ecm to get this to clear?

If reflash is the case insite doesn’t pull up my part number ecm and I can’t access the files on quickserve.

If anyone is able to help me that would be greatly appreciated and if you want to remote in I can pay you for your services I just really need to get this back to work

Hey bro. Dunno if you got this fixed but if you still need help pm me your contact info and I’ll help you get it straight
