Most controllers do that - my factory controller does. The question is, if you unplug the trailer overnight and start the truck the next morning without plugging in the umbilical, how would the P3 controller know that there was a trailer attached to the hitch? As far as the controller is concerned, it's no different than starting the truck the next morning to go on a grocery run without a trailer, right? So why would it flash a Trailer Not Connected warning unless it does this any time you step on the brake pedal, towing or not?

Thanks, I didn't describe my question well enough. :)
