Mandate common interfaces and open hardware. I shouldn't have to buy a $10k dongle to sniff codes. I certainly shouldn't have to buy a different one for each manufacturer.
- fragmede 6mo agoThe legislation has to be robust. No dice if the dongle is generic and $20 like OBD2 in cars, but that on top of that there's a per-manufacturer set of codes that only licensed dealers have access to the software to read those special codes.
- cout 6mo agoThe situation today is at least better than it used to be before OBDII. I much prefer using a scanner to get codes then having to count flashing lights. And back then you'd still have to pay a lot for the manufacturer's code reader. The only advantage was the ROM was small enough to disassemble and reflash with new features. I would not want to do that on a car made in 2026.
