List of OBD-II and Automotive repair software

This is a list of software and hardware that are relevant to repairing and parts of cars and trucks

Terms and concepts

Obviously, all of this is missing many details that are mostly irrelevant to why you are reading this post, You are probably here to figure out what tools you will need, and that is what I will focus on.

  • PID: Parameter IDs: The test software sends IDs and expects error codes or information in return, Some IDs are mandated by the state, other IDs are specific to a manufacturer.
  • response (Ex: Error) codes: Just like the PIDs (The questions- sent by the testing instruments), some responses are mandatory standards and others are manufacturer or car specific.
  • J1979: A standard set of PID/Response codes of which many are mandatory for all vehicles mostly for emissions regulations purposes
  • J1962: A standard for the hardware connector plug you can see under your instrument panel (Under your dash, in the footwell), formally named The DLC (Data link connector), Starting 1996, the OBD-II (OBD2) connector with both its variants (OBDII-A for 12V and OBDII-B for 24V) should be available for all cars sold in the US. Although it is now universal, some cars in other parts of the world didn’t get them until a few years later.
  • ELM327 command protocol:
  • J2534: THE TOOL, A tool that supports the J2534 standard should be able to speak to the vehicle in all of the following protocols (ISO9141, ISO14230 (KWP2000), J1850, CAN (ISO11898), ISO15765, SAE J2610, and J1939 (2005+))
