and automatic transmission control
systems. When these systems are
operating properly, your vehicle will
provide excellent performance and
fuel economy, as well as engine
emissions well within current local
regulations of various countries.
If any of these systems require service,
the system will turn on the
Malfunction Indicator Light (MIL).
It will also store diagnostic codes and
other information, which your
Authorized Maserati Dealer will use to
service your vehicle. Although the
vehicle will still be driveable and not
need towing, contact the Authorized
Maserati Dealer for service as soon as
possible.
CAUTION!
• Prolonged driving with the
Malfunction Indicator Light (MIL)
on could cause further damage to
the emissions control system. It could
also affect fuel economy and
drivability. The vehicle must be
serviced before any emissions tests
can be performed.
•Ifthe
Malfunction Indicator
Light (MIL) is flashing while the
engine is running, severe catalytic
converter damage and power loss
will soon occur. Immediate service is
required at an Authorized Maserati
Dealer.
• After the problem has been solved, the Authorized Maserati Dealer
personnel will perform specific tests
on the test bench for a complete
check of the system and, if necessary,
also road tests, even on long
distances.
In addition, the system is equipped
with
a diagnostics connector that,
when interfaced with suitable
instruments, makes it possible to read
the error codes stored in the ECU,
together with a set of specific
parameters for engine operation diagnostics cycle, on compliance with
CARB, EPA OBDII rules.
CAUTION!
• Once the engine is started, the
Malfunction Indicator Light (MIL)
will remain on for approximately 18
seconds before turning off. This is a
normal condition and part of the
operating strategy.
• When the key in the ignition switch is turned to MAR (ON)position if the
Malfunction Indicator Light (MIL)
does not illuminate or if it
illuminates while driving, contact
your local Authorized Maserati
Dealer as soon as possible.
