Multiecuscan

hi I'm using multiecuscan selected at least three models of fiat Dobo in the program list but I get always this: ISO Code is not valid for this system chosen for this vehicle. What should I do? help me.

Run a scan first to see what controller the car reports as having.
Then make sure you're selecting the correct type of Doblo (the type code is the first 3 numbers in the VIN), the correct model, and the matching control module to what the scan said.
