GETTING TO KNOW YOUR CAR

ALFA ROMEO CODE SYSTEM

This is an electrical engine locking system which increases protec-
tion against an attempted theft of the car. It is automatically acti-
vated 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
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 in-
hibitor.
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 the code is not recognised correctly during ignition,
Y
the warning light comes on in the instrument panel. In this
case turn the key to STOP and then to MAR; if the lock persists
try again with the spare set of keys. If you are still unable to
start the engine contact an Alfa Romeo Authorised Service.
