Identifying PID groups
Data are logs created each time standard diagnostics are run in Diagbox.
So as a start, run a short diag for each of the main groups, Fuel circuit, Air intake, Electrical, Exhaust line, Cooling and Misc with the engine running if possible..
Running the Python script get parameter names.py, will create a text file with a list of the PIDs that were called in the TRC file, followed by a list of the parameters that were retrieved in the XML file.
Looking back through my old logs I found all sorts of stuff, like seatbelt info, button presses, key in starter position etc, It's possible that these were generated during actuator testing.
This is the list of my standard groups, which will give a starting point to find a specific PID
