OBD port FIAT DUCATO 2017 Owner handbook (in English)

EOBD SYSTEM
The EOBD system (European On Board
Diagnosis) allows continuous diagnosis
of emission-related components on
the vehicle to be made.
It also alerts the driver, by turning on
the
warning light in the instrument
panel (together with relevant message
in the multifunction display, for
versions/markets where provided) when
these components are no longer in
peak condition (see “Warning lights and
messages” paragraph).
The aim of the system is to:
monitor system efficiency;
indicate an increase in emissions
due to vehicle malfunction;
indicate the need to replace
components which have deteriorated.
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 control
authorities.IMPORTANT After eliminating the
failure, to check the system completely,
Fiat Dealerships run a bench test and,
if necessary, road tests which may
also call for a long journey.
