Mariva, Vauxhall electricity

I checked and all the fuses are OK, there is any behind the radio module itself from your knowledge? Thank you for your time

What you can try is disconnecting the battery again for 10 mins and then reconnect , sometimes works .

Already tried with no results :(

Dont suppose you can access the various menus and scroll through , checking settings ?

Nope, I can t. I think it's something related to interior sound because I can t hear the seatbelt beeping when not plugged in but I can see the dashboard check light. I can t hear the indicators noise or hazard light but they are working and displaying on dashboard. I can t hear the parking sensors working but the light on the button appears when they are activating. And I can t acces the menu because it s not turning on at all. The horn for example it s working but it has nothing to do with the interior chimes I mentioned above. The symptoms are exactly the ones of a bad fuse or something but they are all fine and I tested each one to see if electricity passes and it does. Please any tips for solving this problem will be much appreciated guys. I've seen that something called body computer module have some fuses on it but I don't know where to find it, maybe it s the one in the engine bay? I checked them too. Is there any possibility the radio module have some fuses attached behind it?

Try pulling the negative off the battery for 60mins not 10 mins as posted in error in earlier post .

Solved the problem, turns out the cp400 burned the battery bc of malfunction, I replaced the radio module. The used one I bought came up locked as an anti theft measure, so I switched the chips on the motherboards and now it s working all fine. I watched the tutorial below to understand what the chips are but instead of re coding it as he does I switched the new one with the other one. Ty all for helping.
