EOBDSYSTEM (European On
Board Diagnosis)
(where provided)
Operation
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, together with a message on the
display, when these components are no
longer in peak condition (see “Warning
lights and messages” paragraph in the
"Knowing the instrument panel" chapter).
The aim of the EOBD system (European
On Board Diagnosis) is to:
monitor the efficiency of the system;
indicate an increase in emissions;
indicate the need to replace damaged
components.
The vehicle also has a connector, which
can interface with appropriate tools, that
makes it possible to read the error codes
stored in the electronic control units
together with a series of specific
parameters for engine operation and
diagnosis. This check can also be carried
out by the traffic police.
IMPORTANT After eliminating a fault, to
check the system completely, the Alfa
Romeo Dealership is obliged to run tests
and, if necessary, road tests which may
also require a long journey.
