SYMBOLS
Some vehicle components have
coloured labels whose symbols indicate
precautions to be observed when
using this component. Under the
bonnet there is also a label that
summarises all the symbols.
THE FIAT CODE
SYSTEM
IN BRIEF
This is an electrical engine locking
system
which increases protection
against attempted theft of the vehicle.
It is automatically activated when
the ignition key is removed.
Each key contains an electronic
device which modulates the signal
emitted during ignition by an antenna
built into the ignition device. The
signal, which changes each time the
engine is started, is the “password”,
by means of which the control unit
recognises the key and enables
starting.

Operation
Each time the vehicle is started turning
the ignition key to MAR-ON, the Fiat
CODE system control unit sends a
recognition code to the Powertrain
Control Module to deactivate the
immobiliser.
The acknowledgement code is sent
only if the Fiat CODE system control
unit has recognised the code
transmitted from the key.
Each time the ignition key is turned to
STOP, the Fiat CODE system
deactivates the functions of the
Powertrain Control Module.
Irregular operation
If, during starting, the code has not
been recognised correctly the warning
light
on the instrument panel turns
on accompanied by the related
message on the display (see section
“Warning lights and messages”).
In this case, turn the key to STOP and
then back to MAR-ON; if the lock
continues, try with the other keys
provided with the vehicle. Contact a
Fiat Dealership if you still cannot start
the engine.
IMPORTANT Each key has its own
code which must be stored by the
system's control unit. Contact the Fiat
Dealership to have new keys (up to
eight) stored with the code.
