Looks like he has a F150 of a similar year to the one I used to own. The truck keeps track of mileage by trailer and you can program it to recognize several trailers through the user interface. As soon as you plug in a 7-pin (it's unaffected by the 4 pin), it automatically starts tracking mileage for the last selected trailer. OP is stating that it's doing this with no trailer actually attached. It can be manually selected to "No trailer", but it shouldn't need to be.
In my opinion, OP has a short somewhere in the truck wiring to the 7 pin or is having a software issue. I'd start by checking the pins on the truck with a multi-meter or using a 7 pin plug-in tester if available and seeing if something's going to ground. - AtleeExplorer IICorrect. That's exactly what it's doing.
At this point, I'll probably just wait until tomorrow when I have an appointment to look at it up at the Ford dealer.IDoMyOwnStunts wrote:

I had a cruise control issue with my previous truck where the cancel button wouldn't work. I thought it was the button, but it turned out to be a software issue and the dealer reflashed the truck. The more complicated they make the plumbing, the easier it is to stuff up the drain.
- pfidahospudExplorerMy 2016 F150 automatically recognizes when an umbilical cord is plugged in, but doesn't "unrecognize" when it's unplugged. Under the "towing" settings on the dash, I have to unselect the trailer manually. I thought this was normal - but maybe not?
- dodge_guyExplorer IIThis almost sounds like a software program issue. Sounds like they need to reprogram it so the truck sees a disconnect from the trailer so you don't have to manually do it!
- Kafn8tdExplorerThe truck should unrecognize it when unplugged.
- BedlamModeratorMy F250 would drop the trailer display when the trailer is completely unplugged but signal "Check trailer" if the plug was not fully seated. My 5500 will show a disconnected trailer when unplugged or partially plugged and will not clear until the the plug is reseated or the ignition is cycled with the plug removed.
- LynnmorExplorerFlush out the connector with contact cleaner, it might be that simple.
- hawkeye-08Explorer IIIAre you disconnecting the trailer while the truck is off? Try doing it with the truck on...
