Abs And Ebd Systems - Maserati GranTurismo Coupe Owner's Manual

ABS and EBD systems

The vehicle is equipped with ABS
(Antilock-Braking System) and EBD
(Electronic Brakeforce Distribution)
systems which, via the ECU and the ABS
sensors, help increase the braking
system's performance.
In the event of an emergency stop or
braking on slippery surfaces (where
there is snow, ice, etc.), the ABS,
together with the conventional
braking system, are disigned to allow
the driver to apply maximum braking
force without the wheels locking and
the driver consequently losing control
of the vehicle.
The system is based on an ECU which
processes the signals transmitted by
the 4 sensors located on the 4 wheels.
When a wheel is tending to lock, the
sensor warns the ECU which, in turn,
informs to the electro-hydraulic unit to
intervene by modulating the pressure
exerted on the brake calipers. The
driver will feel a "pulsing" sensation
coming from the brake pedal, which is
normal.
In the event of a failure, the system will
be deactivated, but this will not affect
the efficiency of the standard braking
system.
The failure is indicated by the red
warning ABS > switching on on the
instrument panel.
In this case, we recommend you
contact the nearest Authorized
Maserati Dealer, which, thanks to the
self-diagnostics system the vehicle is
equipped with, should be able to
identify the problem.
The vehicles must be fitted
with wheel rims, tires and
brake lining of the kind and
make approved for this model by the
manufacturer.
Although this device
contributes greatly to the
vehicle's safety, it is still
essential to drive with particular care,
especially when the road is wet or
there is snow or ice on the road.
The vehicle is equipped with
the EBD (Electronic Brakeforce
Distribution) system. If the
warning light switches on when
the engine is running, this indicates a
malfunction in the EBD system; in this
case sharp braking could lead to the
rear wheels locking too early, and the
vehicle may skid. Driving extremely
carefully, go directly to the nearest
Authorized Maserati Dealer to have
the system checked.
If only the > warning light
switches on while the engine
is running, this normally
indicates a malfunction in the ABS
only. In this case, the braking system
maintains its efficiency, but the anti-
locking device cannot be used. In these
conditions the EBD system may also
function less efficiently. Also, in this
case we recommend you go to your
Authorized Maserati Dealer as soon as
possible to have the system checked,
avoiding any sharp braking while you
drive.
