Yes i know, i tried on 481 protocol and no response. Then i try to connect, i show "on dashboard....", later "on dashboard", "turn off dashboard" and show error "wake up". I try many times. I try to connect OP-COM, op-com can show my ecu model, but can`t show live parameters like a RPM, can show errors and clean errors, but kess via OBD absolutely no work indications. Maybe affecting installed android multimedia? Maybe possible connect to another kess cable direct to dissasembly block? I see on official allientech website "no listed to connect via kess or ktag, but i have ktag pinouts for this denso block".
