DASHBOARD AND CONTROLS -> THE FIAT CODE SYSTEM for Your Fiat Punto SUV 1999-2010

SYMBOLS  
Special coloured labels have been attached near or actually on some of  
the components of your Fiat Punto. These labels bear symbols that  
remind you of the precautions to be taken as regards that particular  
component.  
The plate summarising the symbols used can be found under the bonnet.  
THE FIAT CODE SYSTEM  
To further protect you car from theft, it has been fitted with an engine  
immobilising system. This system 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 modulate 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.  
F0I0073m  
OPERATION  
Each time the car is started turning the ignition key to MAR, the Fiat  
CODE system control unit sends a recognition code to the engine  
control unit to deactivate the inhibitor.  
The 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 the STOP position, the Fiat CODE  
system deactivates the functions of the engine electronic control unit.
