THE FIAT CODE SYSTEM
This is an electrical engine locking system which
increases protection against attempted theft of the
vehicle. It is automatically activated when the ignition
key is removed.
An electronic device, in fact, is fitted in each ignition key
grip. The device transmits a radio-frequency signal when
the engine is started through a special aerial built into
the ignition switch. The modulated signal, which changes
each time the engine is started, is the “password”, by
means of which the control unit recognises the key and
enables to start the engine.
OPERATION
Each time the vehicle is started by turning the ignition
key to MAR-ON, the Fiat CODE system control unit
sends a recognition code to the engine control unit to
deactivate the immobiliser.
The acknowledgement code is sent only if the Fiat
CODE system control unit has recognised the code
transmitted from the key.
Each time the ignition key is turned to STOP, the Fiat
CODE system deactivates the functions of the engine
management control unit.
If the code is not recognised correctly during ignition,
the
Ywarning light comes on on the instrument panel
together with a specific message on the display (see
“Warning lights and messages”).
SYMBOLS
Special coloured plates have been attached near or on
some of the components of your vehicle. These plates
bear symbols that draw your attention to the
precautions required when handling the component in
question.
The plate summarising the symbols used can be found
under the bonnet, fig. 2.
