Maybe someone can help. I read everything I found and also all FAQs etc, but can't get data out of JPDIAG.
I have a KKL cable. The blue one with FTDI chip. LED turns on when connected to 12V.
Both tests work fine. 0V/12V on K-Line and test #2 gives OK as well.
I can work with IAWDIAG 0.5, read values, turn on fan etc.
I run both programs on a Win11 PC, and start JPDIAG in XP-mode and as administrator.
I can connect, and e.g. start the FAN, but more or less nothing else.
I can NOT READ any data, e.g. the data that's needed for registration.
I mainly need the program for TPS calibration, which of course doesn't work either.
Any idea what's going wrong?
BTW: The exact same model as I have with same software version etc is listed here:

As I understood it, this is sent data from JPDIAG so I assume this ECU should work fine?!
