Current Golo carcare sn:9668900xxxxx scanners both facing the same problem: starting the diagnostic normally, but it can't connect OBDII to the vehicle on any protocol standard. (I tried with EOBD software and software for a specific car manufacturer like Ford, Hyundai, Toyota) all reported that it could not connect to the ECU (Tried to fix the firmware OK, reinstall the app ver V2_013, ver2_019) Has anyone encountered the same situation as me?
