I'm trying to get a better understanding of how to interpret the CSV files, e.g. the HVAC.
In this regard I have two questions:
1) If I need to send a request frame to poll the vehicle for 7B3, I assume I need to send a frame as below - is this correct?
7E3 | 03220100AAAAAAAA [initial request]
7E3 | 3000000000000000 [flow control, e.g. after 20 ms]
2) If done correctly, I will receive a number of response frames (as per ISO-TP), from which I'll be able to construct a full 'payload' consisting of the data bytes that contain the specific signals. Assuming this is e.g. 40 bytes long, how would I find the bit start and bit length for e.g. 001_Outdoor Temperature in the above link? I see the mention of G, which I assume refers to a specific byte, but is there a table that explains what byte position this refers to?
