What's wrong, in plain English
Certain Chevrolet Silverado 4500HD, 5500HD, and 6500HD medium duty trucks have a brake pressure sensor assembly that may leak brake fluid into the nearby brake pressure switch. This leak can cause an electrical short circuit, which can overheat the circuit and increase the risk of a fire, whether the truck is being driven or is parked.
