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 turning on the 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:
❒ monitor system efficiency
❒ indicate an increase in emissions due to vehicle
malfunction
❒ indicate the need to replace damaged components.
The system also has a diagnosis connector that can
be interfaced to suitable instruments, 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.
