ScottyGS Posted May 16, 2017 Share Posted May 16, 2017 There seems to be more and more F-150's out there on the forum. I am creating this topic for all of us who have an F-150 and are experiencing or will experience the dreaded Trailer Disconnect Message. This topic will hopefully help us 1.) Understand the issue and 2.) Find a way to lessen / live with it. To start a hearty THANK YOU to all those I have talked to about this, especially Steve / ScubaRX. I also have a request for any who read this thread: PLEASE LIMIT this discussion to the disconnect issue on the F-150 ONLY. Many helpful people who know a lot more about trailer electronics than I do will undoubtedly want to help diagnose grounding issues etc. For the F-150 that would send most folks down a very deep rabbit hole. OK.. and thanks in advance for your help on this. This is what I know / have been able to surmise about the situation: IT's the TRUCK! Not the trailer. If you google F-150 and trailer disconnect you will get a huge amount of hits going back a very long time. Ford must know about this and just not care about fixing it.DON'T worry about your BRAKES! - All the lights and turn signals work fine even when the trucks computer tells you the trailer is disconnected. AND THE BRAKES ARE WORKING TOO! The good news..... no danger, but it still sure is annoying. If you want to check this, use the manual brake controller to apply the brakes when the trailer is showing disconnected. You can also go to the trailer status screen and see the gain when you apply the foot brake. < I worried a long time about the brakes and now its nice to know that they are still there doing their job > This is what I think we might be able to do about it: I read that running a ground jump cable between trailer and truck might help. That is if it is a grounding issue that is causing the trucks computer to think the trailer is disconnected. I am thinking this would involve wire, connectors, screws and drilling some small holes. Does anyone know how to do this? Any help on placing a ground between the truck and trailer would be appreciated. I will get er done and report back on the next trip.Has anyone SOLVED this issue? Either with the help of Ford or on your own?I plan to address this with my local ford dealer, but frankly don't have much hope that they will have a solution. Finally for those planning on buying an F-150 as an Ollie tow vehicle. Everything else about the truck is great. Lots of power. Nice ride. Tows great. And, the Pro Backup Assist helps very much for trailer newbs like me. This is the only issue that drives me a bit crazy. Thanks Everyone... Smooth Roads and Blue Skies!
