I found this out this morning when I tried to start my truck and it wouldn't even crank. Called H&S and they informed me of this situation.
I learned this by accident, too... I got distracted while changing the tune, came back out to the truck and continued- I didn't realize it, but I had selected 'DPF ON tuning'... oops...
it fired up and it started cycling the EGR (audible).. I realized it, looked at the tuner info, and sure enough- I was running a DPF tune on a deleted truck..
I couldn't re-fire it..
then, I went in search of something that was nagging me from way in back in my head- and curiously enough, I had read it here when I first joined- and really had no reason to recall it.. the EGT13 stickied thread in the problems section..
by jumping the sleeved wire next to the passenger battery box to the positive terminal of the battery, you defeat the protocol that has you locked out.. took like maybe five seconds to manage fixing the issue.. it has to do with the pyro's and sensors in the OE exhaust not reporting, and the PCM determining it's time to flip you the bird because of such..
