This one’s just a short post to introduce the next three posts. In our investigations of the MBE 9A4 ECU we’ve found three different diagnostics protocols supported on the OBD port.
The following three posts will summarise what we’ve learnt about each protocol and will be updated with new information as it becomes available.
- 13.1 MBE-Broadcast
- 13.2 OBD-II
- 13.3 MBE-ISOTP
