Trailer Disconnetion Error Code on my Tacoma Dash

I don’t understand poverty buttons. One of the biggest reasons I went with the TRD Off-Road upgrade package was to avoid the sea of blank switches. Honestly, I don’t get why Toyota leaves them there if the feature isn’t included. Why tease us with the empty spots? Even with the off-road upgrade package, there are still empty buttons. It was actually one of the main reasons I upgraded trims in the first place. At the time, I didn’t even care what the buttons did, I just didn’t want to be taunted every day by reminders of what I could’ve had. I’m not even sure what features I’m missing out on. Now that I actually go off-road with the truck, I use the accessory wiring and axle lock, but somehow I still only have the one button on the main console. How much do you actually have to spend to not be reminded daily of what you missed? And what features am I even missing out on with this package?

Yesterday, I had an error on my dash when I plugged in a trailer and unplugged it. The yellow light bulb in the photo above kept coming out. Turns out, I forgot to disconnect the trailer.

I know when you drive without a trailer attached to your truck (like it has been unplugged), you would be asked if the trailer is disconnected, then you would select yes, and it should go out. Worked for me yesterday and I thought I should share.
