In the Maxisys Elite, I was able to go the the live data and it would show me which circuit was at fault--However the additional PID code was not present. I was lucky enough to have access to a DS 708 with old software installed on it & it was able to give me the code (#29 in this case) under the live data. Autel needs to correct this. There is no reason for the DS708 to provide better info than the Maxisys Elite!!
