Trailer Disconnetion Error Code on my Tacoma Dash

[Rico's4G]

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.
