RX Parking Aid Issue

Interesting. When my old Acura TL had similar symptoms, I found corrosion on the radar sensors themselves. Did you already check the sensors for corrosion?

Good point. Where are those sensors usually located? I'll take a look tomorrow.

I believe they are often located near the wheel wells or integrated into the bumpers. Given that a defective cable or plug connection is likely according to the error memory, I still recommend visiting the workshop.

Thanks for the advice. It was indeed a faulty connector. Cost me 95€ to get it sorted. Appreciate the help!
