The electronic components in-
side the key may be damaged
if the key is submitted to sharp
knocks.
OPERATION
Each time the key is fitted into the ignition
switch, the Fiat CODE system control unit
sends a recognition code to the engine con-
trol unit to deactivate the inhibitor.
The code is sent only if the Fiat CODE sys-
tem control unit has recognised the code
transmitted from the key.
Each time the ignition key is removed, the
Fiat CODE system deactivates the func-
tions of the engine electronic control unit.
If the code has not been recognised cor-
rectly, the warning light
Y
(where pro-
vided) turns on accompanied by the relat-
ed message on the display (see chapter
“Warning lights and messages”).
In this case, the key should be removed and
refitted; 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
contact a Fiat Dealership.
IMPORTANT Every key has its own code,
which must be memorised by the system
control unit. To memorise new keys, up to
a maximum of eight, apply to Fiat Dealer-
ship.
THE FIAT CODE SYSTEM
To further protect your car from theft, it
has been fitted with an engine immobilising
system. This system is automatically acti-
vated when the ignition key is removed.
An electronic device, in fact, is fitted in each
ignition key grip. The device transmits a ra-
dio-frequency signal when the engine is
started through a special aerial built into the
ignition switch. The modulate signal, which
changes each time the engine is started, is
the “password”, by means of which the
control unit recognises the key and enables
to start the engine.
Warning light
Y
coming on
when driving
❒ If the warning light
Y
turns on, this
means that the system is running a
self-test (for example for a voltage
drop). At the first stop, turn the igni-
tion key to OFF and then back to
ON: if no failure is detected warning
light
Y
will not come on.
❒ If the warning light Y
stays on, re-
peat the procedure described previ-
ously leaving the key at OFF for over
30 seconds. Should the inconvenience
persists, contact a Fiat Dealership.
