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?
Updated my comment to reflect this. Thanks for clearing out the confusion.
Once it may have been called ALDL instead. My '95 Commodore has one. Assembly Line Diagnostic Link. Same physical connector.
ALDL was proprietary to GM kind of like apple and their connector tomfoolery. In 1990-something CARB probably didn’t want to buy all the different diagnostic tools so they said if you want to drive in California your car needs OBD-II. Now, I can check and clear codes on any modern car with a $35 tool.
1996 model year.
