Consumer Description
While pulling a trailer, truck stops recognizing trailer brake connection without warning. Driver only notices truck brakes are no longer working because trailer is pushing truck while stopping. All other trailer connections, lights, turn signals, are working. When applying trailer brakes from truck controller, truck message says no trailer connected. This problem is intermittent and unpredictable. Sometimes it can be corrected by reconnecting 7 pin adapter but sometimes this does not work and the truck battery has to be disconnected and reconnected. Online forums show this to be a common problem.
