Thank jvanier. It's really helpful. Can you please tell me what 01(5th byte) signifies here: 10 14 49 02 01 33 46 41? Is it indicating that the following bytes are ascii string?
On the first reply from the ECU, the fifth byte is 01. What does that byte mean? (Your VIN appears to start after that)
Also, I suspect you a missing a "3" from the end of the VIN you have in your textual description.
