6.2 service engine soon - no codes????
Like the title says... my service engine soon light has been coming on and going out for a week or so. It cam on for the first time just before i lost the rear brakes. I figured they were related. brakes have been fixed and the truck scanned... No codes came up. The light came on a few times over the weekend. The last time I tapped the dash to be a smart ass and the light went out. I guess I need to make sure it didn't burn out or something. anyone have any thoughts. I was told that the 6.2 Diesels don't really use much of the computer... is this true?
