To increase protection against theft attempts, an electronic immobilizer system known as the ''FIAT CODE-2'' 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. If it recognizes the code sent, it allows the engine to be started up.The code used in the communication, which takes place via aerial, changes each time the car is started up (rolling code). The code cannot therefore be reproduced, even with electronic scanners.The body computer has the task of recognizing the key inserted in the ignition: in effect, the computer contains the secret code used in the dialogue with the key transponder.The body computer contains all enabled key codes in its memory, together with the code used in the communication between the body computer and the engine management unit. When the key is turned to MAR 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 body computer.The Code system has supply lines for the control unit protected by the maxifuse which also protects the engine management system, by the supply fuses for the body computer and the instrument panel locted in the junction unit under the dashboard.
