OBD2 codes

'Hey, does anyone know of a source where I can find information about the communication protocols used in EOBD/OBD2 systems?' 'It's as simple as asking for basic information like the VIN when connecting to the OBD port with an adapter.'
Best regards and thank you.

Everything is defined in SAE J1979. To query the VIN, send: 7DF 8 02 09 02 00 00 00 00 00.
However, you will not be able to receive the entire transmission, because the response is 'Muliframe,' and the first frame must be 'acknowledged' before the control unit will send the remaining frames. Either a trigger needs to be used within the monitoring program, or a custom program needs to be written.

Best regards,

Okay, I need the SAE J1979 standard. But it's definitely not available for free download, right?

'Maybe I'll get it tomorrow, with a lot of luck.'
Thank you.

P.S.: Just to be clear, a request and a response are .
