Hello Owners

I have civic type r ep3 premier edition and today my engine management light came on has I connected obd2 it created a spark on the terminals and it stoped working and now the stereo stoped working and my doors don't unlock and lock and no alarm green light for the symbols in not lit no more
iv checked the fuse for the stereo and it seems fine
I'm not sure where to check which fuse it may be.
