Hi folks,
does anybody know OBD Header for Renault Espace IV 2.0DCi?
I have some custom PIDs created but I have NO DATA message reading with blank OBD Header field.
I have tried 7E0, PID sends back some respond but it doesn't seems to be good.
Thank you
Here is short summary regarding my issue:
PID: 22242C
Header: 7E0
Response: 7E8037F2211
I assume this response is wrong because when I try another PID I got exact same response from ECU.
When PID is 22242C response should looks like 62242CXXYY I guess.
Any suggestions what should cause this?
Is my OBD Header wrong?
Do I need to know ISO code?
Thanks
you must first issue a session initialization command 10C0, and then already issue your PID
perhaps you need to give a synchronization command 1003 instead of 10C0

Thank you for your support.
I have replicated everything from your 3 screenshots, unfortunately I can't connect to ECU with this init AT commands sequence.
When I try init AT commands sequence without ATSP6 line I can establish connection with ECU.
Howewher, PID is still responsing 7E8....in this case.
Is this caused because of missing ATSP6 command?
you need to check the adapter
issue commands from the initialization line in the terminal and post a screenshot of the adapter's responses
when you establish a connection with the ECU, look at the adapter status tab for which protocol the ECU connects
what year is your car?
I took some screenshots based on your request. Hope there is all you tell me to do.
