ALFA ROMEO CODE SYSTEM

This is an electronic engine locking system which increases pro-
tection against attempted thefts of the car. It is automatically ac-
tivated when the ignition key is extracted.
Each key contains an electronic device which modulates the sig-
nal emitted during ignition by an antenna built into the ignition de-
vice. This signal is the 'password' which changes at each ignition
and which the control unit uses to recognise the key and enable
ignition.
OPERATION
The Alfa Romeo CODE system control unit sends an acknowl-
edgement code to the engine management control unit to deacti-
vate the inhibitor each time the car is started by turning the igni-
tion key to MAR.
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
Y
control unit. Warning light
if the code is not correctly recognised during ignition.
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 car. If you
are still unable to start the engine contact Alfa Romeo Authorized
Services.
