Hi, you need to get autoauth on your device plus you need for fiat cars the 12+8 cable to bypass sgw ( secure gateway) otherwise you do not get access to do diagnostics on this car.
Hi., the 12+8 cable need to be bought from a fiat dealer or from internet stores, than you need to get information where the sgw module is mounted in your vehicle to connect the 12+8 cable between after this you can make connection to vehicle.
