Help, I changed the A / C condenser of my 2018 honda crv, and now the radar gives an error and I have a lot of signs on the dashboard.

Ayuda, cambié el condensador de aire acondicionado de mi honda crv 2018, y ahora el radar da un error y tengo muchas señales en el salpicadero.

Are you still running your original battery?

Make sure nothing is in front of the sensor (wire etc.) and that it is clean. A drop or two of oil or residual cleaner can cause problems.
Also check the wiring as you were working in that area.
It's almost certainly not a coincidence this happened just after that work.

I agree with sirwired. Sounds like whoever replaced the condenser, mangled the alignment or connections to the radar array.

The radar array is located where you visually can see what looks like a little black plastic plate immediately below the Honda logo of your front grillwork.

[Update] The symbols disappeared 1 day after driving the car in a cart at high speed, it seems that the radar works again, I will be informing you if I have news.

Did a shop replace the condenser, or did you DIY it? If you had a shop do it, make them fix the problem; they would have had to disturb the radar to get the new condenser installed.
It was a store, they did not know how to solve the radar, I was really disappointing. Miraculously the symbols on the dash disappeared and the radar is working again.

Either something is out of alignment OR your battery is weak.
I second this, either they damaged something, it needs to be recalibrated, due to them working around it, coming into contact with it, or the battery is becoming week, and those systems are not receiving the ample voltage they require, it temporarily working after hitting a cart, is most peculiar. Coincidental, I'm sure...

Is the calibration done with a scanner?

Radar calibration requires a fixed calibration bay set up at a dealership. It has special targets placed according to Honda calibration requirements, and calibration takes an hour or two to complete.

Same with the front facing camera, though it's calibration bay setup is different (optical vs millimeter radar).
