    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

Why don't cars have diagnostic software loaded onto their infotainment centers? (lemm.ee)

Modern cars have MASSIVE digital displays, loads of computers systems monitoring every subsystem and internal diagnostics running to the OBDII ports.

Why the hell can't we get diagnostic feeds on our console or infotainment center?

I'm not aware of any car manufacturers selling their own diagnostic ASICs, so it's not an extra margin to squeeze afaik...

What gives? Any insight into this beyond the usual muh corporate profits conjecture?

They don't want to maintain the software for it.

That's fine, I just want the error codes displayed on the existing screens. No software necessary for that. Maybe a simple script at worst..

Also, they simply don't want you to know.

They want it to be known, otherwise there wouldn't be fail codes output to the OBDII port....

It's meant for diagnostics only.

Yes. Why don't they display diagnostics error codes on the existing displays? I'm fine with special display modes and "secret" menu options.
