On my way into work this morning I had a message come up on my dash saying something about "exhaust system service see dealer now" Truck runs fine and I was pulling my 6k travel trailer. I've never had this come up and everything is deleted and with my programmer I've never had any exhaust messages come up. Anyone have any info on this or where I can look?

 

Hi, just the computer having a brain wave, mine's done that a few times too and i'm fully deleted,turn truck off and restart and it goes away

 

Thanks! I was wondering if it would be something like that. I'll see what happens when I start it after work.
