[QUOTE="TURTLE, post: 820770, member: 1475"] Yesterday I noticed my CEL and abs lights were on after I got to work. I have a cold air intake, the dpf deleted, full egr delete (coolers and valve/elbow), and an h&s minimax tuner with can tunes. The minimax pulled the following codes: P1639- vehicle id block not programmed correctly. P163A- ford generator B control circuit. P0603- internal control module keep alive memory (KAM) error. I was able to clear all except the P1639 code. I can not re-program the truck or return it to stock tuning and get a locked screen reading "Downloader Is installed on truck with this vin "(gives my trucks correct vin)" please return to stock" after completing the tuning sequence in what appears a successful manner as normal. I haven't noticed any issues except lately when it gets cold if I don't wait for the glow plug light to go out plus give it some extra time, when I turn the key it cranks about halfway over, stutters/pauses/ shorts like the batteries are dead, then continues to crank, fire and idle normally. Any ideas or advice how to fix the start and tuning problems would be greatly appreciated. I apologize if this has been covered but the search function isn't working on my phone and my laptop is dead due to too much internet porn. -Cyrus [/QUOTE]
