EOBD SYSTEM
47)
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 warning light
in the instrument panel (together
with the relevant message in the display
on some versions), when these
components are no longer in peak
condition (see "Warning lights and
messages" section).
The goal of the system is to:
❒monitor the efficiency of the system;
❒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.
WARNING
47) If, when the ignition key is turned
to MAR, the
warning light
does not switch on, switches on
constantly or flashes when driving
(on certain versions together
with the message on the display),
contact a Fiat Dealership as soon
as possible. The operation of
warning light may be checked
by the traffic police using specific
devices. Always comply with the
traffic regulations in force in the
country where you are driving.

panelWhat it means What to do
amberINJECTION/EOBD SYSTEM FAILURE
In normal conditions, when the ignition key is turned to
MAR the warning light switches on, but it should switch
off as soon as the engine is started.
The operation of
warning light may be checked by
the traffic police using specific devices. Comply with the
laws and regulations of the country where you are
driving.13)
If the warning light stays on or switches on when driving,
it means that the injection system is not working
properly; in particular, if the warning light comes on
constantly, this indicates a malfunction in the supply/
ignition system that could cause excessive exhaust
emissions, a possible loss of performance, poor
driveability and high fuel consumption.
On some versions, the display shows the dedicated
message.
The warning light switches off if the malfunction
disappears, but it is still stored by the system.Under these conditions, you may continue
travelling at a moderate speed without
demanding excessive effort from the
engine. Prolonged use of the vehicle with
the warning light on constantly may cause
damage.
Contact a Fiat Dealership as soon as
possible.
NOTE (for petrol engine only)
If the warning light flashes, it means that the catalytic
converter may be damaged.In this case, it is necessary to release the
accelerator pedal to lower the speed of
the engine until the warning light stops
flashing. Continue the journey at moderate
speed, trying to avoid driving conditions
that may cause further flashing and
contact a Fiat Dealership as soon as
possible.
