FIAT Idea - Manual (Page 141)

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 turning on the warning light
U on the instrument panel (together, where
provided, with the message on the reconfigurable
multifunction display - see the “Warning lights”
chapter) when these components are no longer in
peak conditions.
The objective is:
❒ to keep system efficiency under control;
❒ to warn when a fault causes emission levels to
increase;
❒ to warn of the need to replace deteriorated
components.
The system also 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
carried out by the traffic police.
IMPORTANT After eliminating the inconvenience, to
check the system completely, Fiat Dealerships are
obliged to run a bench test and, if necessary, road
tests which may also call for a long journey.
