DESCRIPTION

To increase protection against theft attempts, an electronic immobilizer system known as the 'FIAT CODE' system has been adopted.

The keys are fitted with an electronic Transponder device, which sends a coded signal to a special CODE electronic control unit.

The Code control unit contains a secret code used in the dialogue with the transponder in the key inserted in the ignition. If the control unit recognizes the code sent, it allows the engine to be started up

The control unit contains all enabled key codes in its memory, together with the code used in the communication between Code control unit and engine management unit. When the key is turned to ON for for the first time, if the key is identified correctly, the code is transferred to the engine management unit and is then indelibly linked to the Code control unit.
