126KNOWING YOUR CAR
EOBD SYSTEM
The EOBD system (European On Board Diagnosis) car-
ries out a continuous diagnosis of the components of the
car related to emissions. It also alerts the driver, by turn-
ing on the
Uwarning light in the instrument panel to-
gether with a message in the reconfigurable multifunc-
tion display, when these components are no longer in
peak condition (see “Instrument panel warning lights”
paragraph).
The goal of the system is to:
❍to keep system efficiency under control;
❍to signal a fault which causes emission levels to
increase;
❍to signal the need to replace deteriorated components.
The system also has a diagnosis connector that can be in-
terfaced to 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 au-
thorities.
Go to a Lancia Dealership as soon as pos-
sible if warning light
Ueither does not light
up when the key is turned to MAR or if,
while travelling, the warning light comes on either
steadily or flashing (along with a message in the
reconfigurable multifunction display). The oper-
ation of the warning light
Umay be checked by the
traffic control authorities using specific devices.
Always comply with the traffic regulations in force
in the country where you are driving.
IMPORTANT After eliminating the problem, to check the
system completely, Lancia Dealerships run a bench test
and, if necessary, road tests which may also call for a long
journey.
