Clutch Bleeding:
Clutch bleeding procedure:
The guidelines of the procedure are illustrat-
ed below:
When?
For filling after draining for KIT repairs.
After KIT repairs following replacement of
hydraulic parts (valves, pump, pressure
sensor, delivery pipe)
General KIT operation
Why?
The routine is designed to eliminate the
possible presence of air in the hydraulic
circuit following the replacement of one of
the above mentioned components carrying
out 15 clutch opening/closing cycles with
the oil pump activated.
What tools are needed?
Diagnosis equipment
NOTES:
The procedure takes approximately 1 minute.
Power latch takes approximately 15 seconds.
To verify the implementation of the proce-
dure it is possible to hear the operating of
the clutch solenoid valve and the activation
of the power unit pump.
The procedure is performed under the fol-
lowing conditions:
Engine off
Brake pressed
Ignition ON
Clutch position sensor ok
Clutch actuator ok
The procedure will end without indicating an
error code if any one of the conditions listed
above does not occur.
Hydraulic circuit depressurization:
The guidelines of the procedure are illustrat-
ed below:
When?
Before the hydraulic components replace-
ment KIT repair (valves, pressure sensor,
supply pipe, etc.).
Why?
The routine is designed to drain the hy-
draulic circuit sending it to the kit fluid
reservoir to allow the replacement of the
above components, carrying out 26 clutch
opening/closing cycles with the oil pump
deactivated.
Oil level check.
What tools are needed?
Diagnosis equipment.
NOTES:
The procedure takes approximately 1 minute.
Power latch takes approximately 15 seconds.
To verify the implementation of the proce-
dure it is possible to hear the operating the
clutch solenoid valve.
Check (read RDI 1C06) that the pressure in
the hydraulic circuit is under the accumulator
pre- charge threshold (approx. 2-3 bar).
The procedure must be carried out in the fol-
lowing conditions:
Engine off
Brake pressed
Ignition ON
Clutch position sensor ok
Clutch actuator ok
The procedure will end with self-calibration
KO if any one of the conditions listed above
does not occur.
