thank you eddy,

that was, i don't have any restistance between pin 6 and 14 but the error is the same(this elm can connect to any can module).
Can somebody recomend me a good interface for a fiat grande punto from 2005 1.3 mjet? (that blue one with switch for abs, ecu, esp, airbag is good?)

thank's

Can you recomand me a particular type of interface? Or how to test it? Because they look the same and they have diferent hardware.

Thank you very much!
