2023 F150 Lane Centering Disabled while towing, WHY?

[ThePnsh3r]

Easiest way to do this would be to splice into tail lights and then connect that to. Another 4 pin connector on the rear bumper. I’ll probably just disconnect current wiring at my 4 pin connector and wire that to tail light splice

Yep, even when something is plugged into the factory 4 pin it detects that as a "trailer" and disables lane centering



Aftermarket trailer brake controller?? ha. Don't count on the dealership telling you much or even knowing anything about it. The only versions would be an older version and I doubt you want to go that route, if even possible at this point.

I had the driver door weather stripping flutter as well. Its something different with 23s as the B pillar trim piece sticks/bends out more so the window seal doesn't have as much pressure. I ended up having to stick some some foam in the seal to tighten it up and solved it right away.

Can't help on the shavings, if its on the dipstick of all places, that's not good...

Lots of great info here! Thank you

Giving this a bump to see if anyone has been able to resolve this, or at least identify

I'm not big on lane centering anyway, so this doesn't affect me. I only use it when extremely tired and not when towing, because I always got the sway from it going back and forth and getting progressively worse. Now I'd be pissed if they took adaptive cruise away while towing. I use cruise while towing more often than I don't.

Still trying to find a resolution/work around as we speak. Just got back from my 1300 mile trip weekend pulling my single axle trailer, and I just ran majority of the time with it unplugged just to make lane centering work on the interstate. Don't worry, my tail lights are clearly visible with it unplugged so no issues there. But this seriously sucks it doesn't work like it use to on 21-22 rigs. When I got home last night I even fiddled around with some more Forscan changes and still no go. At this point, all I want is my trailer lights to function as they should and lane centering to work with them plugged in. I will, and almost already have, disabled every trailer backup, auto hitch, brake, nanny there is and still no go. I'm 99% certain as soon as it see resistance on the trailer lights connection, it senses a trailer attached and hard coded in newer software it disables LC. So if I can disabled the trailer sense somehow, but still maintain all the light functionality, that is the end goal now.

BUMP in case anyone has been able to resolve this or at least identify specific variation where lane centering with towing is disabled. Otherwise I am getting ready to tap into tail lights and put another plug for the trailer in the back.

When towing with my 21 PB I could keep Lane Assist on. It wasn’t a good idea as it caused the trailer to sway.

Glad to hear yours works - you're one of the lucky ones. I've had a similar issue with my prior truck and load re-distribution fixed that. Issue that many of us are having now is that on some trucks the feature would not engage if a trailer is connected.

I've also tested towing my current trailer, with the new truck, and with the plug disconnected the system worked great with zero issues or sway (just like my 2022 did).

I see this is an older thread, but I have a '21 XLT and pulled a small airstream behind. Lane Centering was amazing and a huge advantage for us.

After I recently "updated" my software in FDRS, I have now LOST the lane centering ability!!!! I am beyond furious.

Has there been any fix/reversion for this?
