The Maserati CODE system

In order to increase protection against
attempts at theft, the car is equipped
with an electronic engine immobilizer
system (Maserati CODE), which is
automatically activated when the
starter key is removed.
Each starter 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 recognized by the system.
The keys supplied are two of type A
and one "valet" key, B.
A A B
Key A can be used for all functions.
Key B is used for:
– ignition
– alarm activation/deactivation.
It can be used when the vehicle is left
with a garage or parking facility, as it
allows the staff to move the car but not
to open the glove compartment (if it is
closed beforehand with the main key)
or the luggage compartment.

Operation

Each time the ignition key is removed
from the STOP position the protection
system activates the engine
immobilizer.
Upon starting the engine, when the
key is turned to the MAR position:
1) If the code is recognized, the CODE
on the instrument panel turns off
within a second, while the OBDII
warning light, once the ECU diagnosis
has been completed switches off after
about four seconds. Under these
conditions, the protection system
recognizes the key code and
deactivates the engine immobilizer.
When the key is turned to AVV, the
engine starts.
2) If the warning light CODE
remains on and the warning light
OBDII , switches off and comes on
again immediately, after the four
second diagnostics for the ECU control
units, the code has not been
recognized. In this case, it is advisable
to turn the key back into position STOP
and then back to MAR; if the
immobilizer stays on, try with the
other keys. If it is still not possible to
start the engine, try the emergency
start-up procedure (see chapter
"Emergency starting" on page 144)
and contact your Authorized Maserati
Dealer.
Driving with the ignition key on MAR:
1) If the warning light CODE
switches on, it means that the system is
carrying out a self-diagnosis check. At
the first stop you can test the system:
turn the engine off by rotating the
ignition key to the STOP position and
then turn the key back into position.
MAR: the warning light CODE
switch on and off within a second. If
the LED stays on, repeat the procedure
described previously leaving the key at
STOP for more that 30 seconds. If the
problem persists, please contact your
Authorized Maserati Dealer.
