M2 Sketch

Upload THIS SKETCH to your M2, which queries the vehicle's Engine Control Unit (ECU) for the VIN and then writes it to a text file via the onboard SD slot.

Collect VIN

With the vehicle running, plug M2 into the OBD-II port. M2 should flash yellow lights as it queries for the VIN, then light up green for success or red for failure. In either case pressing button 1 will make M2 try again, writing a new text file each time.
