Use of the engine
Engine control system OBDII
This system continuously monitors the
components of the vehicle related to
emissions; it also warns the user about
the deterioration condition of the
components themselves, by means of
the warning light
U
on the
instrument panel.
The objective is the following:
– keep engine systems operating
efficiently
– indicate when a problem causes an
increase in emissions exceeding the
threshold established by federal
regulations
– indicate the need for replacement of
deteriorated components.
In addition, the system includes a
diagnostics connector that can be
interfaced with suitable instruments.
This makes it possible to read the error
codes stored in the control unit,
together with a set of specific
parameters for engine operation
diagnostics, in compliance with
OBDII
rules.
WARNING: When the ignition key is
turned to the
MAR position, if the U
warning light does not switch on or if
it switches on while driving, contact
your
Authorized Maserati Dealer as
soon as possible.
WARNING: After the problem has been
eliminated, your
Authorized Maserati
Dealer personnel is required to
perform tests of the system and if
necessary, also road tests.
