Fault signals
If one or more electric components in
the system malfunction while driving,
the ECU illuminates the relative
warning light
accompanied by the
message “Check suspensions” on the
display. In addition, the ECU calibrates
the shock absorbers to a preset value,
thus ensuring a safe vehicle set up.
Should the fault involve one shock
absorber only, this is no longer
controlled by the electronic control
unit and remains in the position it had
when the fault occurred. It is therefore
possible that one of the four shock
absorbers has a fixed calibration,
differing from that of the other ones.
In any case, a safe and secure car
driving at low speed is always
guaranteed.
WARNING: In the event of a
malfunction in the electronic system
controlling the suspensions, which is
indicated by the warning light
on
the display switching on while driving,
you should keep a moderate speed and
have the vehicle checked as soon as
possible by the Maserati Service
Network.
If a malfunction occurs while driving,
signalled by the warning light
on
the display switching on, it is advisable
to stop the vehicle as soon as possible
and turn the ignition key to the STOP
position and then re-start the engine.
If the malfunction is no longer present
and the warning light
on the
display does not switch on again, the
electronic suspension system will
resume normal operation.
On the other hand, if the problem
persists, the warning light
on the
multi-function display will switch on
again.
In both cases, the system must be
checked by the Maserati Service
Network.
The detected fault is memorized by the
electronic control unit and can be
diagnosed at a Maserati Service
Network Centre even if it has
disappeared spontaneously.
