Arduino + Canbus-shield

Hi,

I’m experiencing troubles with arduino UNO and your canbus-shield.

I’m trying to execute both your canbus_v3 and caninterface codes.

In the first case when I connect OBDII cable to cars (I tryied with fiat punto Evo, Fiat 600, Lancia Ypsilon) I receive the message “CAN init ok” and the led begin to flash (I think it is executing the main loop), but it seems no CAN messages arrives.

With caninterface software when I connect the OBDII cable it says “CAN Failure”.

Can you help me ???

thank you very much.
