I think no way to "disable" to make the car start. Look why comms with security module is not working. ;)

In fiat models there is mostly a trick to skip the crash signal and start the engine,....
This trick works with switching flash lights on off in a certain time and order ;-)

I try this, but don't works:
* turn ignition key to MAR;
* turn on right turn signal;
* turn off right turn signal;
* turn on left turn signal;
* turn off left turn signal;
* turn on right turn signal;
* turn off right turn signal;
* turn on left turn signal;
* turn off left turn signal;
* turn ignition key to STOP.

it will not work if you are doing this in that order - you have to wait till turn indicator light in dash Shows you that you should Switch on Signal ;-) i also had same Problem with Fiat 500 - till i recognized to wait till control lamp Shows me in dash,..... i think description in tech book is not 100% correct ;-) hope this helps,....

Those Italians make fun of their clients, right turn signal, left turn signal, blink, maybe horn twice... turn radio on, then off... f**ck, what is the point of this exercise...
