P1621 code?

I keep throwing a P1621 code...Control module long term memory loss. Any of you guys know what this is. I've never ran my DTC's and not thrown this code.

This is a typical Bully Dog DTC, nothing to worry about. Basically it means you left your key in the ignition for to long.

Like I said, it sets when you load the bully dog, and it pops up. This code means absolutely nothing, and will go away as soon as you remove the Bully Dog from your truck.
