EOBD SYSTEM
The EOBD system (European On Board Diagnosis) pro-
vides a continuous diagnosis of the car’s emission-related
components.
It also alerts the driver, by way of warning light U light-
ing up on the instrument panel (together with the relevant
message on the multifunction display, where provided) (see
section “Warning lights and messages”), when these com-
ponents are no longer in peak condition.
The goal of the system is to:
❒ keep the system efficiency under control;
❒ warn when a fault causes emissions levels to increase;
❒ warn of the need to replace non-performing compo-
nents.
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 traf-
fic police.
IMPORTANT After eliminating the problem, to check the
system completely, Fiat Dealerships run a bench test and,
if necessary, road tests which may also call for a long jour-
ney.
