Wait for the procedure to end.
Repeat the procedure if unsuccessful.
C) Bleed the clutch hydraulic circuit using command AC008 "Clutch circuit phase 1 bleed".
Wait for the procedure to end (this should take 6 minutes).
D) Bleed the clutch hydraulic circuit using command AC009 "Clutch circuit phase 2 bleed".
Wait for the procedure to end (this should take 8 minutes).
E) In order for the following steps to run smoothly, check that parameter PR145 "Engine coolant temperature" is
below 50 ˚C.
Clear all programming using commands:
–RZ002 Programming,
–RZ003 Program biting point,
–RZ008 Initial closed position of clutch.
Exit fault finding mode and switch off the ignition.
Wait 1 minute and then re-establish dialogue with the computer.
F) Program the gears using command VP008 "Programming selection/engagement zones".
Wait for the procedure to end.
Exit fault finding mode and switch off the ignition.
Wait 1 minute and then re-establish dialogue with the computer.
Check that programming has been successful by referring to the following status:
ET061 “Gear programming” displays “DONE”.
Brake and select all the gears in the gearbox, while checking that they are recognised on the display. Repeat
procedure G if not done. WARNING
For all operations on the hydraulic circuit, activate commands AC006 "Hydraulic unit pump inhibition"
and AC081 "Discharge pressure accumulator" until the hydraulic pressure PR018 “Hydraulic pressure” is
close to zero.

HIGH PRESSURE PIPE
A) Switch on the ignition.
B) Apply the following command:
–RZ001 Stored faults.
Exit fault finding mode and switch off the ignition.
Wait 1 minute and then re-establish dialogue with the computer.
C) Rehabilitate the hydraulic unit using command AC007 "Hydraulic unit pump rehabilitation".
Open the bleed screw,
Gearbox in neutral position, handbrake engaged, engine speed zero and no fault with the solenoid valves and
the master slave sensors.
Bleed the clutch hydraulic circuit using command AC008 "Clutch circuit phase 1 bleed".
Close the bleed screw as soon as the fluid begins to run clear of air bubbles.
Wait for the procedure to end (this should take 6 minutes).
D) Bleed the clutch hydraulic circuit using command AC009 "Clutch circuit phase 2 bleed".
Wait for the procedure to end (this should take 8 minutes).
E) Exit fault finding mode and switch off the ignition. WARNING
For all operations carried out on the hydraulic unit, run commands AC006 Disable hydraulic unit pump
and AC081 Discharge pressure accumulator.
Use command AC081 until hydraulic pressure is close to zero.

CLUTCH OR GEARBOX + CLUTCH
A) Switch on the ignition.
B) Clear all programming using commands
–RZ002 Programming,
–RZ003 Program biting point,
–RZ008 Initial closed position of clutch.
Exit fault finding mode and switch off the ignition.
Wait 1 minute and then re-establish dialogue with the computer.
C) Rehabilitate the hydraulic unit using command AC007 "Hydraulic unit pump rehabilitation".
Bleed the hydraulic circuit.
Open the bleed screw,
Start the engine with the handbrake applied.
Gearbox in neutral and no faults in the solenoid valves or master slave sensors.
Bleed the hydraulic circuit using command AC025 Bleed slave cylinder hydraulic circuit.
Repeat procedure C if not done.
D) Check that PR145 "Engine coolant temperature" is below 50 ˚C.
Program the gears with command VP008 Program selection/engagement ranges.
Wait for the procedure to end.
Exit fault finding mode and switch off the ignition.
Wait 1 minute and then re-establish dialogue with the computer.
Check that programming has been successful by referring to the following status:
–ET061 “Gear programming” displays “DONE”.
Brake and select all the gears in the gearbox, while checking that they are recognised on the display.
Repeat procedure D if not done.
E) Shift the selector lever to neutral.
Start the engine.
Wait 10 seconds without changing gear (to program the clutch biting point).
Repeat the clutch biting point programming 4 or 5 times.
Check that programming has been successful by referring to the following status:
–ET062 “Biting point programming” displays “DONE”.
If “NOT DONE”, repeat procedure E. WARNING
For all operations on the hydraulic circuit, activate commands AC006 "Hydraulic unit pump inhibition"
and AC081 "Discharge pressure accumulator" until the hydraulic pressure PR018 “Hydraulic pressure” is
close to zero.

Fault finding - Interpretation of commands
CLEARING

ACTUATORS
RZ001 Stored fault(s)
This command is used for clearing the stored faults from the computer.
RZ002 "Programming"
This command enables the gear programming to be cleared.
Use this command each time parts are replaced (see Replacement of components).
RZ003 "Biting point programming"
This command enables the clutch biting point programming to be cleared.
Use this command each time parts are replaced (see Replacement of components).
RZ008 "Initial closed position of clutch"
This command enables the initial closed position of clutch programming to be cleared.
Use this command each time parts are replaced (see Replacement of components).
AC006 "Disable hydraulic unit pump"
This command enables inhibition of the hydraulic pump.
AC007 "Hydraulic unit pump rehabilitation"
This command enables rehabilitation of the hydraulic pump after the computer has been
replaced or after the inhibition of the pump using command AC006
Hydraulic unit pump inhibition.
AC008 "Clutch circuit phase 1 bleed"
This command is used to perform the first clutch circuit bleeding phase after an operation
with parts replacement (see “Replacement of components”).
This command takes 6 minutes.
AC009 "Clutch circuit phase 2 bleed"
This command is used to perform the second clutch circuit bleeding phase after an
operation with parts replacement (see Replacement of components).
This command takes 8 minutes.
AC011 "Hydraulic pressure unit bleed"
This command is used to bleed the hydraulic pressure unit after an operation with parts
replacement (see Replacement of components).
