Technical reverse camera not working

[Buko]

Hi, I recently bought a Fiat 500X and everything seems to be cool, but I don't know where to start solving the problem of a non-working reversing camera, it does not display the image only an error on the radio screen and on the computer two errors U1451-87 and U0422-86.

Where to start, what could be the reason? how to reach those plastics in the flap to get to the camera and its plug, maybe I'll start with that?

Have a look at this DIY. Should give you an idea of the wiring.

I managed to remove this plastic from the flap and remove the blend, when I opened it, the hooks broke, but it's nothing if I fold it, I'll glue it together somehow, but. inside there was a lot of water, everything was wet, I opened the camera and there were also traces of the presence of water on the plate. bath in the washer with isopropanol did not give anything, the same error and lack of image from the camera. I hope that nothing in the radio broke, only something in the camera burned out, etc. the camera that is in this blend is 00520493940 but where to get one, or maybe another one that looks the same but is, for example, with Dodge Challenger 2015-2017 from aliexp will work?

camera that I bought on Ali arrived for a Dodge Challenger as I wrote and in general it is an original Mopar camera, the same in appearance and plug socket, the cable I also had to make from another car because the old one had one pin burned out, but when I connect the cable described as LIN it unfortunately does not work, when I unplug it works, I do not know if something else could have burned somewhere further because the old plug from the old camera had just this pin burned out. Also the parking lines are missing even though they are enabled in the settings in the radio, but I think it might be due to this LIN does anyone have any idea how to figure it out? because either the camera identifies itself differently through LIN and that is why it shuts down or something somewhere is burnt or something unfortunately there are no cameras for 500x alone anywhere
