Abs And Ebd Systems - Ferrari 612 scaglietti Owner's Manual

ABS and EBD systems

The vehicle is equipped with ABS (Anti-Lock Braking System) and
EBD (Electronic Brake Force Distribution) systems which, by means
of the ABS system sensors and the ECU, improve the braking system
performance.
In the event of an emergency stop or braking on slippery surfaces (e.g.,
snow, ice etc.) the ABS, together with the standard braking system, is
designed to allow the driver to apply maximum braking force without
causing the wheels to lock and consequently losing control of the
vehicle.
The system is based on an electronic control unit that processes the
signals coming from 4 sensors fitted inside the circuits on the 4 wheels.
When a wheel tends to lock, the sensor warns the ECU which, in
turn, signals to an electro-hydraulic unit to activate by modulating the
4
pressure exerted on the brake callipers; the driver feels a "pulsation" of
the brake pedal, which is completely normal.
In the event of a failure, the system will be deactivated, but this will not
affect the efficiency of the standard braking system.
A failure is indicated by the relative warning light on the instrument
panel coming on.

In this case we recommend that you contact the nearest authorised
service centre of the Ferrari Service Network who will immediately
identify the fault by means of the system self-diagnostic function.

ERRARI
Despite the fact that this device makes a considerable
contribution to safety, it is still essential to drive
particularly carefully when the road surface is wet, covered
with snow or ice.
The vehicle is provided with Electronic Brake force
Distributor (EBD). The warning light comes when the
engine is running to indicate a fault in the EBD system: in
this case, sharp braking could cause the rear wheels to lock
too early, and the vehicle may skid. Carefully drive to the
nearest service centre of the F

the system checked immediately.
The failure warning light usually comes on with the
engine running to indicate a fault in the ABS system
only. In this case, the braking system maintains its efficiency,
but the anti-locking device cannot be used. Under these
conditions also the EBD system efficiency may be reduced.
Carefully drive the vehicle, avoiding sharp braking, to the
nearest service centre of the F
