|Hello paulius,thank you so much for your answer,I appreciate a lot.
As soon as possible I will take it a try and I will reply the result.
In the past I have seen that the 0x3A3 id byte was correlated with the ignition
so the byte was 0x00 with ignition off and 0xFF with the ignition switched on
but I was not totally confident that was the right id to watch to...
Thank you again.
In CAN traffic you can see a lot of IDs who are changing with Ignition. Because you see not only ignition status, but also status of a lot of ECUs (i.e. climatronic). And they are "on" with ignition.
Usually ignition is just 1bit. In my example are 3bits, because i'm checking 3 status together (ACC (s-contact), ignition and Klemme 75).
ID 0x3A3 comes from Engine ECU.
Your byte shows something like "car ready" status. 0xFF means 100% ready (something like this).
