In the midwest, a bunch of gunk got in the trailer connector, on the truck side. it only took a few minutes to disconnect clean and blow out and add a bit of dielectric grease. has been fine now for the last 12k miles or so. Received 1,030 likes on 624 posts. random trailer connected disconnected messages. like the title states. driving down the road the "trailer connected" message will just pop up in the display. and then it goes away. a short time later the "trailer disconnected" message appears. it then sometimes goes away or sometimes repeats the cycle a couple.
1) we received the trailer light module failure when stopping at a stop light on return home trip. 2) when testing at home the running lights all work, including the left running light. but the left turn signal and brake light did not work. 3) took ford to dealer and they installed the trailer brake recall upgrade. To say i am pissed off if huge understatement. that warning ("check trailer wiring") would display and then the message "trailer connected" would generally happen immediately (sometimes after a few seconds). this could be random, or it could happen rapid fire a dozen or more times. the truck is a 2015 3500 duramax. For $26 i ordered a new connector and swapped it. problem solved. 2015 2020 ford f150 trailer disconnected message fixed hey there, this issue was a pain to find accurate information on so i will post this here for others to see. i bought a used 2015 f 150 xlt and a brand new travel trailer shortly after. A service trailer brake system warning message means that your truck is equipped with a wiring harness or integrated trailer brake control (itbc) system that can control trailer brakes, and there is a problem somewhere in those components. there can be multiple reasons for a “service trailer brake system” message or warning light, and we.

I'd pull all the fuses that are associated with the hitch to make sure they're good. then start the car, and see if the light goes out. if it does, then put the fuses back in one at a time, starting the car each time. if the light comes back on after reinserting a fuse, then at least you have an idea of which circuit is bad. Experiencing warnings like "service electronic braking system" and "service trailer brake system" on your low mileage truck can be concerning. start by checking trailer connections for any damage or loose wires if a trailer was recently used. verify the brake fluid level in the truck, ensuring it meets the recommended level, as low fluid can.
