Practical usage tips

  1. Verify adapter compatibility: Use a recommended OBD-II/CAN adapter that supports the protocols your target vehicles use.
  2. Start with VIN scan: Let the software auto-detect the vehicle where possible to maximize correct ECU match and functions.
  3. Record before clearing codes: Export or screenshot fault lists and freeze-frame data before clearing DTCs for reference.
  4. Compare live data: Use live sensor streams to confirm faults rather than relying solely on stored codes.
  5. Update when possible: Check for software updates periodically to improve vehicle coverage and bug fixes.
