EOBD SYSTEM
The EOBD system (European On Board Diagnosis)
allows continuos diagnosis of the components of the
car correlated with emissions.
It also alerts the driver, by the turning on of the
warning light
U on the instrument panel together
with the message on the reconfigurable multifunction
display (where required) (see section “Warning lights
and messages”), when these conditions are no longer
in peak conditions.
The objective is:
❒ to keep system efficiency under control;
❒ warn when a fault causes emission levels to increase;
❒ warn of the need to replace deteriorated
components.
The system has a diagnostic connector that can be
interfaced with appropriate tools, 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
performed by traffic controller agents.
IMPORTANT After eliminating the inconvenience, to
check the system completely, Fiat Dealership is obliged
to run a bench test and, if necessary, road tests which
may also call for a long journey.
If turning the ignition key to MAR, the warning light U does not turn on or if, while travelling it
turns on glowing steadily or flashing together with the message on the reconfigurable multifunction
display (where required), contact Fiat Dealership as soon as possible. Warning light
U operation
can be checked by means of special equipment. Always comply with the traffic regulations in force
in the country where you are travelling.
