Hello,
I have a problem with my 2016 Rc-350. I'm not the first owner, but i know that the car was sitting in some water, but then was repaired, worked perfectly until now, on the dash it sometimes flashes the pcs with no pattern, when i connect the machine to reed the errors it shows that the car looses connection, the right rear view mirror stopped working and the tyre pressure doesn't read. I've taken apart all the interior and checked the connections the wires, but nothing any suggestions?

 

What exactly were the codes? I mean assuming water intrusion, maybe the plugs aren’t fully seated or snagged. I had PCS, parking, a bunch of lights go off bc my front end was hit and it snagged my front speed sensor

 

Update, I solved the problem of the mirror and tyre pressure, and now i just have PCS flashing sometimes, no error codes just PCS error light comes on the dash for a second and disappears
