Info

• 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); 5. the clutch closes. 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. IMPORTANT
This value must never exceed the clutch travel value prescribed for the car. • If it is still possible to read the value that had been recorded on the TCU Diagnosis page, set this value in the new TCU.
