GETTING TO KNOW YOUR CAR
122
EOBD SYSTEM
The EOBD (European On Board
Diagnosis) system fitted in this car
complies with Directive 98/69/CE
(EURO 3).
This system continuously monitors
the engine emission system compo-
nents. Furthermore, the system warns
the driver of deterioration concerning
the emission system components by
means of
U warning light on the in-
strument panel.
The objective is to:
– monitor system efficiency;
– warn when failures can increase
emissions over the threshold estab-
lished by the European regulations;
– warn of the need to replace dete-
riorated components.
Furthermore, the system is equipped
with a connector for interfacing with
specific tools used to read the error
codes stored in the control unit mem-
ory along with a set of diagnostic and
engine specific parameters.
This check can also be performed by
traffic controller agents.
If, turning the ignition
key to M, the warning
light
U does not turn on
or if, while travelling it turns on
glowing steadily or flashing, con-
tact a Fiat Dealership as soon as
possible. Dealership as soon as
possible. Warning light
U
oper-
ation can be checked by traffic
controller agents by means of
special equipment. Always com-
ply with the traffic regulations in
force in the country where you
are travelling.
IMPORTANT After eliminating the
problem, your Fiat Dealership will
run a bench test to fully check the sys-
tem. In some cases, a long road test
may be required.
TYRE PRESSURE
MONITORING
SYSTEM - T.P.M.S.
(where provided)
The car can be equipped with the
T.P.M.S. (Tyre Pressure Monitoring
System). This system consists of a ra-
dio-frequency sensor, installed on each
wheel (on the rim inside the tyre) that
sends pressure information to the
control unit.
IMPORTANT System control unit
monitors the pressure of the four car
tyres but not the space-saver spare
wheel. It is therefore recommended
to always check also the space-saver
spare wheel pressure.
IMPORTANT Pay the attention
when checking or inflating tyres. Ex-
cessive pressure impairs road holding,
increases suspension and wheel stress
and causes abnormal tyre wear.
