A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 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?

I think it's more that the protocol is universal across the industry even though engines are all built somewhat differently, so you can only have a generic code to tell you what's wrong.

I mean the errors that are shown on the car dashboard. If it's an error about the lambda sensor, it will just say "engine error, please contact dealer" or something like that
