Have a 2015 6.7 with 2900 miles. Drove it this past weekend an hour away and back. Once I got back I removed a lot of parts to get ptm (bumpers, grille, mirrors etc). Cranked it a few times during the disassembly. I started the truck today to move it and CEL is on haha wtf. Only thing electrical that was disconnected was the back up camera and fog light harness which I plugged back in and obviously did not make a difference. I won't get the parts back for awhile, and I'm assuming this has nothing to do with removing bumpers, etc or does it? Just seems like a really weird coincidence
