PIDs according to J1979? The vehicle itself discloses them in the PIDs dividable by 0x20, where each bit indicates the availability of one of the next 32 PIDs.

PIDs according to J1979? The vehicle itself discloses them in the PIDs dividable by 0x20, where each bit indicates the availability of one of the next 32 PIDs. Each PID is described in great detail by SAE, too, no manufacturer specific information needed for interpretation.
Anything that is not J1979 but purely manufacturer defined though, is a different story, and making that available is the main reason for the existance of the regulation.

- Youden 4y agoTo be fair, my use of the terminology might be completely wrong. By "PIDs", I mean in general the identifiers I send to the car to retrieve information.
