Trailer Detected Warning Stuck On

[TRDTACO]

Howdy!

I have a 2024 Taco. I don’t own a trailer or anything to attach to my hitch. But sometimes when I am hauling something around in my bed, I get this warning. Well, this past weekend when I was hauling something in my bed, the warning came on and now it’s stuck on. I saw a couple other threads about connecting a trailer and disconnecting it but the problem is I don’t have anything like that. I’m not sure how to turn it off. Could it be something that after so many miles it just goes off on its own?

There's a TSB that should fix it.

Thanks, I’m not familiar with what TSB is? Tech Service Bulletin?

If you know of any documentation that I could follow I’d appreciate. Thanks for the help!

I just want to update this thread in case it helps anyone else. I took it to the dealer and had them run the TSB code mentioned in this post. And unfortunately, it didn’t work. They did tell me of a method to hook up a trailer drive it forward 6 feet then unhook the trailer and that should do the trick. But the problem is I don’t have a trailer.

So I thought about how the issue started. And it’s when I put something that I was moving in the bed of my truck with the tailgate down and the issue is that it recognizes a trailer for some reason when there is weight in the bed and the tailgate is open. I made the mistake of clicking OK that a trailer was connected when it actually wasn’t and that’s how it got stuck being on.

So now that I’m home, I tried opening the tailgate and I put two dumbbells on the tailgate to give it some weight and sure enough it detected a trailer again, and I was able to cancel and turn it off.

Weird how it all worked out but in case anybody else needs a strange trick like that there you go.

Is there an easy location to track or reference the general list as it grows?
(I don't see TSBs as a bad thing, they show actively trying to address issues that are showing a trend)

I suspect there is, but don't know of one.

I, the human driver, request an option to manually turn off trailer towing mode. Because apparently this truck’s computer has no clue I’m not towing a trailer.
Why not connect it with the Drive Mode / Tow Mode knob? When I’m Eco, normal or sport - no trailer. When in Tow mode, enter Trailer Type menu. None of this is difficult.

Yea, I'm with you. This whole menu tree should be tied to the tow mode switch. If the tow mode isn't engaged, none of the tow functionality should work.

I don’t know what the engineers are doing around that place, but I don’t think any of them collaborate. Each subsystem in this vehicle doesn’t seem to communicate with the another seamlessly.
(By the way, really love your white truck)
