360 Modena gear box manual - All Ferraris

which are detected each time the system is started.
The second point depends on the clutch wear and is detected whenever a gearshifting
has been completed.
Being acquainted with these points makes it possible to monitor friction material wear
and to modify the car pick-up parameters in order to have always the same conditions
when the car is started and for the entire clutch life.
Moreover, a gearshift regulating system has been introduced so to keep the system
performances steady, until the clutch is worn out.
To calculate the clutch wear trend, the TCU must contain the information relating to
the thrust bearing when the clutch is new and closed.
Each time the clutch is replaced, the closed clutch position at 0 km must be stored in
the TCU. This operation must also be performed whenever the TCU is replaced (
D 6.11).
Safety functions
The system is endowed with several safety functions, which are mainly used for:
• Avoid an improper use of the system.
• Detect any malfunction, signal it to the driver and manage recovery procedures in
order to reach a service centre without causing the car's stopping.
ATTENZIONE
In the event that the gearbox failure warning light switches on ( H 1.02), the car
efficiency may be strongly reduced. In these cases, take the car to a service centre to
make all necessary checks.
• Protect the transmission mechanical components thereby guaranteeing their long
life.
• Enable the system start-up.
• Accept the driver's commands.
To prevent potentially dangerous situations arising from an improper use of the car,
the system is equipped with functions which make it even safer than a normal
mechanical transmission:
• In the event that the requested gear-shifting would cause the locking of the wheels
or the engine runaway speed rate or even an engine speed below idling, the
command is not be accepted.
