Electronic boards pretty much never fail in cars. They have no moving parts and the chips are encased in epoxy or resin. When it fails it’s pretty much always connected sensors, cabling or fuses or other external parts. And the board can usually tell you what part if you read out the error codes.

That’s no different than the car, basically. Mechanics don’t really independently diagnose stuff on modern cars anymore. They plug in the OBD scanner and the car tells them what might be wrong.
What’s easier to diagnose, your fuel pump just died or there’s a faulty diode on a board tucked up underneath literally everything?

There is always need for a master mechanic to figure out the hard / weird stuff. But for every one of them you need 6 parts replacers to read codes.
