THE FIAT CODE SYSTEM

This is an electrical engine locking system which increas-
es protection against attempted theft of the vehicle. It is
automatically activated when the ignition key is extracted.
Each key contains an electronic device which modulates
the signal emitted during ignition by an antenna built in the
ignition device. This signal is the 'password' which changes
at each ignition and which the control unit uses to recog-
nise the key and enable ignition.

OPERATION

Each time the car is started by turning the ignition key to
MAR, the Fiat CODE system control unit sends an ac-
knowledgement code to the engine management control
unit to deactivate the inhibitor.
The 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 engine man-
agement control unit.
If the code is not recognised correctly during ignition,
Y
the warning light comes on in the instrument panel
accompanied by the related message on the display (see
section "Warning lights and messages").
