EOBD ENGINE
U
CONTROL SYSTEM
FAILURE (amber)
(for versions/
markets where
applicable)
In normal conditions, turning the ignition
key to MAR, the warning light turns on,
but it should go off when the engine has
started. The initial turning on indicates that
the warning light is working properly.
If the warning light stays on or turns on
when travelling (on some versions the mes-
sage + symbol are shown on the display):
glowing steadily - means a fault in the
supply/ignition system which could cause
high emissions at the exhaust, possible lack
of performance, poor handling and high con-
sumption levels. In these conditions it is pos-
sible to continue driving without however
demanding heavy effort or high speeds. Pro-
longed use of the car with the warning light
on may cause damage. Contact Alfa Romeo
Authorised Services as soon as possible. The
warning light goes off if the fault disappears,
but it is still stored by the system;
80
a flashing - indicates the possibility of
damage to catalyst (see "EOBD system"
in this chapter). If the warning light flashes,
it is necessary to release the accelerator ped-
al to lower the speed of the engine until the
warning light stops flashing; continue the
journey at moderate speed, tyring to avoid
driving conditions that may cause further
flashing and contact Alfa Romeo Authorised
Services as soon as possible.
If, turning the ignition
key to MAR, the U warn-
ing light does not turn on
or if it turns on glowing steadily or
flashing when travelling, contact
Alfa Romeo Authorised Services as
soon as possible.
ALFA ROMEO CODE
Y
SYSTEM
(amber)
Turning the ignition key to MAR the warn-
ing light (if fitted) flashes only once and
then go off. If, with the ignition key at
MAR, the warning light stays on, this in-
dicates a possible failure (see "Alfa Romeo
CODE system").
IMPORTANT The turning on at the
same time of the U and Y warning lights
indicates a failure of the Alfa Romeo CODE
system.
For the versions equipped with reconfig-
urable multifunction display: if with the en-
gine running the message + symbol are
shown on the display, contact Alfa Romeo
Authorised Services.
If, with the engine running, the Y warn-
ing light flashes (on some versions togeth-
er with the message + symbol on the dis-
play), this means that the car is not pro-
tected by the engine inhibitor device (see
"Alfa Romeo CODE system" in this chapter).
