CODE DESCRIPTION

Description

To increase protection against theft attempts, an engine immobilizer system known as the FIAT CODE-2 is used.

The keys are equipped with an electronic Transponder device that sends a coded signal to a special electronic CODE control unit. If the code transmitted is recognised as valid, the control unit allows the engine to be started.

Because the code used in the communication - which takes place via aerial - changes at each start-up (rolling code), the code may not be reproduced even using electronic scanners.

The CODE control unit and the engine management unit exchange information on the code received from the key inserted. If the code of the key in question is correct, the engine management control unit enables engine ignition.

The entire system is protected by dedicated fuses housed in the engine bay and under-facia junction unit and a further maxifuse housed in the battery control unit.
