EOBD SYSTEM
The EOBD system (European On Board Diagnosis)
allows continuous diagnosis of emission-related
components on the vehicle.
It also alerts the driver, by turning on the
Uwarning
light on the instrument panel (together with a relevant
message in the multifunction display, for versions/
markets where provided) (see “Warning lights and
messages” section), when these components are no
longer in peak condition.
The goal of the system is to:
❒keep the system efficiency under control;
❒warn about increased emissions due to a vehicle
malfunction;
❒warn of the need to replace deteriorated
components.
The system also has a diagnostic connector that can be
interfaced with appropriate equipment, which makes it
possible to read the error codes stored in the control
unit together with a series of specific parameters for
engine operation and diagnosis. This check can also be
carried out by traffic control authorities.
IMPORTANT After eliminating the problem, to check
the system completely, Fiat Dealerships run a bench test
and, if necessary, road tests which may also call for
a long journey.
If, when the ignition key is turned to the
MAR-ON position, the Uwarning light
either does not come on or, when driving,
it comes on constantly or flashing (along with
a message in the multidirection display,
for
versions/markets where provided
) contact a Fiat
Dealership as soon as possible. The operation of
the warning light Umay be checked by the
traffic control authorities using specific devices.
Always comply with the traffic regulations in
force in the country where you are driving.
