had the same issue trying to read srs codes on a 2007 vauxhall astra 1.6 and i got this ''THE SELECTION FUNCTION IS NOT SUPPORTED''. all my firmwares were up to date. after contacting autel US and ASIA, i was told to format the sd card and reinstall only the firmware for vauxhall. but that did not work either. Autel needs to sort this out as people are buying your products and not getting whats its stated to be doing.
