Fiat Ducato - Eobd System

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
U warning 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 mal-
function;
❒ warn of the need to replace non-performing compo-
nents.
The system also has a 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
police.
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.

INDEX
If, when the ignition key is turned to the
MAR position, the U warning 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 pos-
sible. The operation of the U warning light may be
checked by the traffic authorities using specific de-
vices. Respect the regulations in force in the coun-
try where you are driving.
