Hello, Thanks for reply but I done what. I think my CTC is a problem, When i test it without power (12V from car) everything on test looking green. When i plug(give_ external power i have errors mostly 2 , but only when i have plus CTC to OBD. Plunging external power to (pin 4,5"-") and pin 16 "+" give me no errors. I think that's why my Passtrue mode don't work.
