One user feedback: ECUHELP KT200II can’t connect to Audi MED 9.1.1, it showed “Turn the dashboard off and back on, then wait for 10s before proceeding.” (shown as the following image), then I click “ok”, nothing shows again.
And this user attached the images with pinout on ecu connection and make process entire.
Advice:
Advise try the pinout, just brown and white, and remove big + , try it safely.
Finally, tested ECUHELP KT200II to read Audi MED 9.1.1 on Bench 100% ok, then this user can write 100% ok too.
