The Fiat Code System; The Keys - Fiat 500L Owner's Handbook Manual

THE FIAT CODE
SYSTEM
This is an electronic engine locking
system which increases protection
against attempted thefts of the vehicle.
It is automatically activated when the
ignition key is removed.
There is an electronic device in each
key which can identify the signal
emitted, when the engine is started,
from an aerial built into the ignition
switch. The signal is the "password",
different every time the vehicle is
started, through which the control unit
recognises the key and enables
starting.
OPERATION
Each time the vehicle is started by
turning the ignition key to MAR, the Fiat
CODE system control unit sends a
recognition code to the Powertrain
Control Module to deactivate the
immobiliser.
The code is sent only if the Fiat CODE
system control unit has acknowledged
the code received from the key.

Each time the ignition key is turned to
STOP, the Fiat CODE system
deactivates the functions of the
Powertrain Control Module. If, during
starting, the code is not correctly
recognised, the warning light
switches on in the instrument panel. In
this case, turn the key to STOP and
then to MAR; if it is still locked, try again
with the other keys that come with the
vehicle. Contact a Fiat Dealership if
you still cannot start the engine.
Activation of warning light while
driving
If the warning light switches on, this
means that the system is running a
self-diagnosis (for example due to
a voltage drop). Should the fault persist,
contact a Fiat Dealership.
