The Code System - Fiat DOBLO 2016 Owner's Handbook Manual

7) It is absolutely forbidden to carry out any
after-market operation involving steering
system or steering column modifications
(e.g.: installation of anti-theft device) that
could badly affect performance and safety,
cause the lapse of warranty and also
result in non-compliance of the vehicle with
type approval requirements.
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.
1)
Operation
Each time the vehicle is started turning
the ignition key to MAR, the Fiat CODE
system control unit sends a recognition
code to the Powertrain Control Module
to deactivate the inhibitor.
The acknowledgement code is sent
only if the Fiat CODE system control
unit has recognised the code
transmitted from the key.
