ALFA ROMEO CODE SYSTEM
To further protect your car from theft, it has been fitted with an engine
immobilising system. It is automatically activated when the ignition
key is removed.
Each key contains an electronic device which modulates the signal
emitted during ignition by an antenna built into the ignition device. 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 car is started by turning the ignition key to MAR, the
Alfa Romeo CODE system control unit sends an acknowledgement
code to the engine management control unit to deactivate the inhibitor.
The code is sent only if the Alfa Romeo CODE system control unit has
recognised the code transmitted from the key.
Each time the ignition key is turned to STOP, the Alfa Romeo CODE
system deactivates the functions of the engine management control
unit. If, during starting, the code is not correctly recognised, the
warning light switches on in the instrument panel.
In this case, turn the key to STOP and then to MAR; if it is still locked,
try again with the other keys that come with the vehicle. If you are
still unable to start the engine contact Alfa Romeo Authorized Services.
Activation of warning light while driving
❒
If the warning light switches on, this means that the system is
running a self-diagnosis (for example due to a voltage drop).
❒
If the warning light remains on, contact Alfa Romeo Authorized
Services.
The electronic components inside the key may be damaged
if the key is subjected to strong shocks.
