Incredibly confused... major problem or not?

I posted here a few months ago that my ETC light inexplicably turned on during a camping trip. I have a 2021 Ram 1500 Hemi. I took the tailgate off so I could fit our golf card in the bed of the truck while we tow our camper trailer. The truck handles the weight beautifully and I am really happy with its performance, but the ETC light went on almost immediately. I called the dealer near our campground, took it in, they ran the logs but the only thing coming back were warnings that the communication to the tailgate camera wasn't working (no kidding, it was no longer connected). Got home, but the tailgate back on, and the ETC light went away.

Went camping again this past weekend - same exact setup, same exact issue with the ETC light.

This is the only time the ETC light has ever come on.

Also, since I bought the truck, the horn honks whenever I start the truck, but only on a cold engine (and not 100% of the time). I took it in to the dealer and they couldn't replicate the issue (most likely because the engine was still warm, which I told them seemed to be the differentiator).

In any case -- anyone have advice/solutions for either of these issues?

I would ignore both issues.

Did you install the camera blank off device that should have been in your glove box?

Yes -- I put on both of the adaptors that are on that wiring harness.

Try it with-out the adapters.I regularly pull my tailgate off at the track,and have never once plugged the adapters in,and have never had a code pop up,but then again mines a 4th Gen,and maybe the 5th Gen trucks are differant
