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
warning
light in the instrument panel (together with 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 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 diagnosis connector that can
be interfaced with 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.
WARNING
If, when the ignition key is turned to the
MAR-ON position, the warning light
either does not come on or, when driving, it
comes on permanently or flashes (along with
a message in the multifunction display for
versions/markets, where provided), contact a
Fiat Dealership as soon as possible. Operation
of the indicator
may be verified by traffic
control officers using the appropriate
equipment. Comply with the laws and
regulations of the country where you are
driving.
