Hi, i’ve a CAN BUS shield and i can’t receive any information from my car (Volkswagen Golf VI).
I use the Audio unit connector to connet to can circuit. I’ve a CanUSB cable and i can read and send CAN message trough the audio unit Connector.
The speed of CAN is 100Kbit.
I’ve tried with the can example but when connect the shield to my car i can’t see any message from serial monitor and the rx/tx led don’t blink.
i attach image for explain.
The wire in the serial connector is:
- red +12v
- black ground
- yellow can+
- green can -
Where i wrong???
