I’m having a project now which is using Sparkfun Can Bus Shield and Arduino Uno to read my car information by OBD-II port. But my car OBD-II is using IS09141-2 protocol.
When I connect the shield to my car using the OBD-II to DB9 cable, nothing is shown. I’m wondering is it due to the jumper for pin configuration on the shield. Currently I did not use any of the jumper.
Hope someone can help me on this.
