With mentioned gateway now in place, and the car happily charging (therefor awake) in my front yard, and what seems to be a fairly good description of all diagnostic fields, it is SO much easier to peek into the car’s diagnostics. So, on my laptop I made a little program plowing through the database of diagnostic commands of the EVC (motor controller), the LBC (battery controller) and the CLIM (heater / airco computer), request every known diagnostic frame, pull out the values of each frame and write that back into the database. We are talking over 3000 values for these 3 computers only.
I can see the pressure in the Airco circuit, which is not fairly low as it was not running, but laso things like the positions of every airflow valve.
Here some data from the LBC.
