Ok so I go in a customers rig. He just bought it at auction. They seemed to think it was a great Idea to pull what ever they had in it out before the Auction.
Truck has straight pipe off the turbo to 5in all the way back. I went in and turned off all the codes I could find<from a thread above, andI do NOT Have any codes but the DIC still says "Clean Exhaust Filter". I drove it for 60 miles today and no change.
Anyone having a problem with the DIC stuck with the "Clean Exhaust Filter" message?
