HRV Overvoltage Error

I have a 2013 Honda HRV diesel with 226242 km. I'm getting an overvoltage error causing all sorts of problems, many fault memory entries, some systems failing, weak battery when starting, and general electrical malfunctions. I suspect the battery is heavily discharged or defective, what do you think?

I also have a Honda HRV. I had similar electrical issues a while back; a power surge fried a few things. Have you checked the voltage regulator? That could be the culprit causing the overvoltage and draining your battery.

Thanks! Where is the voltage regulator located, and is it easy to test?

Honestly, I'm not entirely sure where it's located on the HRV specifically. I didn't tackle the repair myself; things got a bit too complex for my liking with all the electronics involved. Considering you're seeing widespread electrical malfunctions, it's probably best to get it checked out by a professional to avoid causing further damage. A faulty voltage regulator can definitely cause the issues you're describing, but a proper diagnosis is key.

OK, I understand. Thanks; I'll take it to a workshop. It turned out that the battery was faulty and needed replacement, causing the overvoltage, as initially suspected. Repair bill was 290€. Appreciate the help!
