Engine control system (EOBD)
The EOBD (European On Board
Diagnosis) fi tted in the vehicle
complies with EC directives:
715/2007/EEC and 692/2008/EEC
(Euro 5).
This system continuously monitors the
components of the vehicle related
to emissions; it also indicates, when
the warning light
on the instrument panel, that the
components in question are in poor
condition.
The objective is the following:
- keep system operating effi ciently
under control;
- indicate when a problem causes
5
an increase in emissions exceeding
the limits established by European
regulations;
- indicate the need for replacement
of worn components.

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 specifi c
parameters for engine operation
diagnostics.
WARNING: When the ignition key
illuminates
is turned to MAR, if the warning
light
illuminates while driving, contact the
Maserati Service Network as soon as
possible.
WARNING: After the problem has
been corrected, the Maserati Service
Network personnel is required to
perform tests on the test bench for a
complete check of the system and, if
necessary, also road tests which may
even involve long distances.
