360 Modena gear box manual - All Ferraris

• Reading the parameters on the Ferrari Tester, check for consistency in the
engagement and selection position signals by performing "open loop" gear-shiftings.
When everything is working properly
• The actuation features the following sequence (see "Time history" D 6.04):
1. the clutch opens;
2. the gear is disengaged (both eng. solenoid valves are triggered);
3. if required, a gear is selected (eng. solenoid valves are triggered according to
the table data);
4. the requested gear is engaged (sel. solenoid valves are triggered according to
the table data);

List of procedures to be carried out after replacing a system component
PIS setting (*)
Repeat the starting procedure 3 or 4 times, with the engine cold and switching off the
system each time until the display is off.
IO setting (*)
Before carrying out this operation, use the SD-2 tester to check that the hydraulic oil
temperature ranges between 38 and 83 °C. With the engine running and neutral
engaged, hold the car at standstill keeping the accelerator pedal released for ca. 2
minutes.
New closed clutch value (*)
New clutch
Using the Ferrari Tester and with the engine off, read the clutch travel value and write
it in the clutch replacement procedure, in the Diagnosis page.
In the event that the TCU (and not the clutch) is replaced, and the value that had been
previously recorded in its Diagnosis page cannot be read, carry out a few pick-up
trials on the car and modify the value to be set as follows:
• if the car picks-up over 1700÷1800 rpm, the set value must be decreased;
• if the car shows interferences or picks-up too sharply, the set value must be
increased.
