completed, verify, by getting connected to the
vehicle by means of the diagnosis instrument, that no
error is found in the gearbox control unit fault
memory.
NOTE

Some modifications or repairs that affect the ESV1 system components, automatic transmission, require a calibration procedure.
The repairs that require this operation are detailed as follows:
-
Replacing the gearbox kit + control unit
-
Replacing the control unit only
-
Replacing the clutch actuator
-
Replacing the gearbox actuator
-
Replacing an electric motor of the gearbox actuator
-
Replacing the engaging fork
Replacing the gearbox wiring requires no calibration procedure.
NOTE
Calibration in case of replacement of the gearbox kit + control unit
The control unit must be programmed (no error in the memory) by providing the same with the vehicle data, e.g. axle ratio, rolling
radius, strength curve, etc.
Get connected to the vehicle by means of the diagnosis instrument, with the vehicle stationary, engine OFF and gearshift lever
in neutral.
Carry out the operations indicated by the instrument: key ON (engine ON), then the dedicated calibration procedure will be
started
→ ” Adaptation of touch Point.
Message “service” will appear on the display; the system in automatic mode will carry out the following operations:
- opening the clutch;
- engaging the 5

or 6
th
speed;
- he clutch closes three times searching for the point of initial slip (the vehicle will pick up three times);
- putting the lever in neutral;
- closing the clutch.
The procedure is interrupted when the engine is switched off.
Wait 10 seconds prior to the next KEY ON.
NOTE
When the procedure has been completed, check the control unit memory and verify that no error is found.
