EOBD SYSTEM
The EOBD system (European On Board
Diagnosis) carries out a continuous
diagnosis of the components of the
car related to emissions. It also alerts
the driver, by switching on the warning
light on the instrument panel, when
these components are no longer in
peak condition (see “Warning lights and
messages” chapter).
The aim of the EOBD system
(European On Board Diagnosis) is to:
monitor system efficiency;
indicate an increase in emissions;
indicate the need to replace
damaged components.
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.
WARNING 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.
