OBD port FIAT PANDA 2009 169 / 2.G Owners Manual

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
authorities.
IMPORTANT After eliminating the failure, to check the sys-
tem completely, Fiat Dealerships run a bench test and, if
necessary, road tests which may also call for a long journey.
EOBD SYSTEM (petrol versions)The EOBD system (European On Board Diagnosis)
achieves a continuous diagnosis of the components of the
car correlated with emissions. It also alerts the driver, by
turning on the warning light
U
fig. 89 on the instrument
panel – together with relevant message in the reconfig-
urable multifunction display (for versions/markets, where
provided) – when these components are no longer in peak
condition (see “Warning lights and messages” chapter).
The goal of the system is to:
❒
keep the system efficiency under control;
❒
warn when a failure causes emissions levels to increase;
❒
warn of the need to replace deteriorated components.
If, when the ignition key is turned to the
MAR position, the
U
warning light either
does not come on or, when driving, it
comes on constantly or flashing – along with a
message in the reconfigurable multifunction display
(for versions/markets where provided) – contact a
Fiat Dealership as soon as possible. The operation of
the
U
warning light may 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.
