Hello, greetings,

I'm coming to you for advice. I have a small car repair shop and some time ago my cousin brought me a MAZDA 6, 2012 with a gasoline engine that crashed into a wild boar. It was a hit to the left front light up to the wheel. During this impact, the radio stopped working. I changed everything and also replaced the DCDC Converter because it was damaged and the indicator light and brake light were on and there were also some errors recorded regarding DCDC. The problem is that my radio still doesn't work and my airbag is flashing. The airbag light is because the airbag light in the center panel doesn't work. Also, my heated seats and parking sensors, which have controls in the center panel, don't work and the rain sensor doesn't work either.

The errors that I blame DELPHINA for are:

FBCM - U0231 rain detection module

Air conditioning - U300E ignition input on

Airbag - Passenger off indicator

I checked all the fuses inside and also by the engine and also the wiring around the converter and everything is fine. I ordered the converter from aliexpress. My next step: I plan to disassemble the center panel and look there is a good grounding but before that I want to ask if you have any idea what I need or where the problem could be.

Thank you

Well you have done everything I may have done? The one thing however after an accident as you explained and the electrical issues, if the battery load tested ok then I would have done an ECU pass-through (flash) (assuming you have one in your shop?) with the latest version or whatever is available. I would do this before replacing any unconfirmed parts at random without verifying they are at fault or failed?
