I have a 2015 Ford Expedition with the integrated electric brake controller system. When I connect my small travel trailer and start the engine, I get a message on the info panel on the dashboard "Trailer Connected". (This is always good news.) However, as soon as I start to pull the trailer, I get a message "Trailer Disconnected" along with two "dings". When I slow down to a stop, it reconnects (and "dings" once). As, I accelerate from the stop, I get the disconnected message again. This thing is constantly dinging and telling me the trailer status connected/disconnected/connected/disconnected and is driving me crazy.
The brakes seem to work fine, even when the status is "Disconnected".
I need to get this figured out and fixed.
I've used a tester that has a "trailer simulator" and have no problems. All lights work on the trailer and as I said, the brakes seem to work fine also at all times.
So, I guess I need to know what it is that the truck is detecting that would make it think the trailer is "disconnected"? Then, I can try to figure out what is exciting that failure mode from the trailer (assuming it is not some kind of wiring fault or logic fault in the controlling software on the truck).
Can anyone tell me what is happening when I accelerate that would cause the truck to think the trailer has become disconnected? Any tips on how to troubleshoot this? (The dealer has tested the wiring and say's all seems good.)
