Description

DESCRIPTION

To increase protection against theft, an electronic engin e lock system is applied, called "FIAT CODE".

The keys are fitted with an electronic "Transponder" device that transmits a coded signal to a special eleetronic "CODE" control unit.

The Code control unit contains a secret code used in the dialogue with the key Transponder inserted in the ignition switch. If the control unit acknowledges the code, it enables the engine activation.

In fact, inside the control unit all the codes of the enabled keys and the code used for dialogue between Code control unit and e.i. control unit that manages the engine are stored: when the key is turned to RUN the first time, if the key is è correctly acknowledged, the code is transferred onto the e.i.control unit, that remains permanently bound to the Code control unit.

For further details see DESCRIPTION AND OPERATION: 5580E.

The Code system power supply lines are protected by the maxifuse and power supply fuse situated near the e.i.control unit, and that also protect the injection system.
