Hello, first post here, really hoping to find some helpful advice...
While checking the fuses in the box behind the cab of my 2016 NPR HD I inadvertently pulled the fuse for the SCR (selective catalytic reduction). Now, even with the fuse reinstalled, I’m getting a warning light on the dash that says EXT SYSTEM. I’ve driven the truck around a bit and it doesn’t seem to be in limp mode or have any performance issues. But I need to clear this light ASAP as the truck needs inspection this month. Really trying to avoid going to the dealership. Any help would really be appreciated! Thank you!
