Cycled the key and P0573 Brake Switch 1 High code has popped up. The truck is an 04.5 3500 48re. I just purchased the truck a few weeks ago and before I bought it, the dealer had new rotors and pads installed in the rear. I've had some brake noise coming from what seems from the front driver's side. I haven't pulled the wheel yet, but after seeing this, it seems I need to. Just wondering what exactly this code means and what I need to look for. Thanks in advance everyone, I'm new to the Cummins world but have a background in the Powerstroke 7.3.
