GETTING TO KNOW YOUR CAR
9
The codes of any keys not
presented during the mem-
orising procedure are
erased. The reason for this is to en-
sure that any lost or stolen keys
cannot be used to start the engine.
OPERATION
Each time the ignition key is turned to the
STOP position the Alfa Romeo CODE system
deactivates the functions of the engine elec-
tronic control unit.
Each time the car is started turning the ig-
nition key to MAR, the Alfa Romeo CODE
control unit sends a recognition code to the
engine control unit to deactivate the in-
hibitor. The code is crypted and variable be-
tween over four billion possible combina-
tions, and it is sent only if the system con-
trol unit has recognised the code transmit-
ted from the key which contains an elec-
tronic transmitter, through an aerial wound
around the ignition switch.
If the code has not been recognised cor-
rectly, the Alfa Romeo CODE warning light
(
Y
) on the cluster turns on.
In this case, the key should be moved to
the STOP position and then back to MAR;
if the lock continues, possibly try again with
the other key provided with the car. If it is
still not possible to start the car, follow the
instructions given in the “In an emergency”
chapter and then contact Alfa Romeo Au-
thorised Services.
IMPORTANT Turning on of the Alfa
Romeo CODE warning light (
Y
) when trav-
elling with the ignition key at MAR:
1) If the warning light turns on, this means
that the system is running a self-test (for ex-
ample for a voltage drop). At the first stop,
it will be possible to test the system: switch
off the engine turning the ignition key to
STOP; then turn the ignition key to MAR:
the warning light turns on and should go off
in about one second. If the warning light
stays on, repeat the procedure described pre-
viously leaving the key at STOP for over
30 seconds. Should the inconvenience per-
sists, contact Alfa Romeo Authorised Ser-
vices.
2) For versions without the reconfigurable
multifunction display, the flashing of the
warning light means that the car is not pro-
tected by the engine inhibitor device. This
condition for cars with reconfigurable mul-
tifunction display is shown by the turning on
of the warning light together with the dis-
play of the message: “C
ODE SYSTEM NOT PRO-
GRAMMED”. Contact Alfa Romeo Authorised
Services immediately to have all the keys
memorised.
IMPORTANT Every key has its own
code, which must be memorised by the sys-
tem control unit. To memorise new keys, up
to a maximum of eight, apply solely to Al-
fa Romeo Authorised Services taking with
you all the keys in your possession, the
CODE card, a personal identity document
and the car’s ownership documents.
