The Maserati CODE system

In order to increase protection against
attempts at theft, the vehicle is
equipped with an electronic engine
immobilizer system (Maserati CODE),
which is automatically activated when
the ignition key is removed.
Each ignition key contains an
electronic device which transmits a
code signal to the Maserati CODE
control unit, and engine ignition is
enabled only if the key code is
recognised by the system.
Two keys are supplied with the vehicle.
The key can be used for:
– start-up;
– door central locking;
– activating/deactivating the
passenger's airbag (European
version only);
– electrical and manual opening of the
luggage compartment;
– activating/deactivating the alarm
system.

Operation

Each time the ignition key is removed
the from the STOP position, the
protection system will activate the
engine immobilizer.
When the key is turned to MAR , upon
engine start-up:
1) If the code is acknowledged, the
warning light CODE on the
instrument panel will off within a
second, while the EOBD warning
light, once the ECU diagnosis cycle has
been completed, will switch off after
about four seconds. Under these
conditions, the protection system
recognizes the key code and
deactivates the engine immobilizer.
Turn the key to AVV to start the
engine.
2) If the CODE warning light stays
on and the EOBD one goes off
after four seconds and then comes on
again immediately, the code is not
recognised. If this occurs, turn the key
to STOP and then back to MAR. If the
immobilizer stays on, try with the
other keys. If you still cannot start the
engine, try the emergency start
procedure and contact the Maserati
Service Network.
