What's wrong?
The parking brake pressure switch is part of the air-brake circuit on affected 2018-2020 Kenworth T680 and T880 tandem axle trucks. Its job is to sense air pressure and tell the cab controller whether the parking brake is set or released. On trucks with certain automated manual transmissions, that signal helps the truck understand whether it should stay held or allow gear engagement.
The problem is inside the switch. A polymer membrane in the switch moves too slowly when the cab temperature is below 25°F. When the driver sets the parking brake, the switch can delay the signal that pressure has dropped. During that delay, the transmission controller does not receive the brake-set message at the right time, and the truck can move unexpectedly.
The warning sign is on the dash. The transmission selector indicates a forward or reverse gear, and the parking brake icon does not illuminate. If you see that combination, treat it as the sign tied to this defect.
