IMPERATIVE: Use only new brake brake fluid that is not emulsified, avoid any
ingress of impurities into the hydraulic circuit.
IMPERATIVE: Do not use automatic bleeding equipment
(risk of the brake fluid
emulsifying in the hydraulic circuit).
Couple a transparent tube (5)on the bleed screw, at «c».
Submerge the end of the tube (5)in the recipient containing the brake fluid, located
below the level of the clutch slave cylinder.
Use the transparent tube (5) to act as a siphon, at «b».
WARNING: the end of the tube (5) must be submerged in the brake fluid.
Open the bleed screw at «c».

Procedure for initialising the automatic gearbox ECU
Downloading.
Updating the gearbox ECU by downloading:
- Follow the procedure using the diagnostic tool.
The downloading operation enables the automatic gearbox to be
updated, or adapted to an evolution of the engine ECU.
Before commencing the downloading, take the value of the oil usage
counter present in the automatic gearbox ECU.
After the downloading operation, carry out the following:
- A clearing of faults.
- An initialisation of the auto-adaptives.
- A writing of the value of the oil usage counter previously read.
- A road test.
ESSENTIAL: Every update of the automatic gearbox ECU should
be accompanied by an update of the engine ECU.Updating the value of the oil usage counter.
Using PROXIA.
Access to reading and recording of the oil counter is via the menu:
- «Configuration
(integrated circuit button)/Oil counter».
Adjustment of the oil counter value is done in incremental steps of
2750 units.
Using LEXIA.
Access to reading and recording of the oil counter is via the menu:
- «Oil counter».
Adjustment of the oil counter value is done by entering directly
the 5 figuresof the oil counter.

Precautions to be taken.
Work with care to avoid entry of polluting particles into the circuit.
NOTE:The correct operation of the system requires perfect cleanliness of the fluid and of the
hydraulic components.
Check:
- The level of the power steering fluid.
- The condition of the piping and unions.
Using the tools.
Prepare the checking assembly [1], [2], [3], [4], [5], [6]and [7].
Attach the tool [1].
Remove the front RH wheel, the splash-shield and the screen wash reservoir.

CHECKING THE POWER STEERING ASSISTANCE PRESSURE
Preliminary operation.
Move aside the high pressure pipe (1).
Do up:
- The union [6]on the power steering electropump.
- The union [7]on the high pressure pipe (1).
- Tighten all the unions.
Fill the power steering reservoir 10 mmabove the max. level.
IMPERATIVE: Use new power steering fluid for both filling and topping-up the circuit.
Open the tap [5].
Start the engine and allow it to run for 5 seconds.
Stop the engine.
Move the steering several timesin each direction.
Check the steering fluid level and make sure that there are no leaks.
Checking the electropump pressure.
Start the engine.
Close the tap [5]for 5 seconds.
Open the tap [5].
Stop the engine.
At accelerated idle
(1200 to 1500rpm), the pressure should be 105 ± 5 bars.
If the electropump pressure is correct, check the valve sealing.

CHECKING THE POWER STEERING ASSISTANCE PRESSURE
Fill the power steering reservoir to the max.mark «a»on the cap (4).
Engine stopped, move the steering slowly from lock to lock, in both directions approx. ten times.
Top up the fluid to the max. mark «a»on the cap (4).
Run the engine at idle for 3 minutes, without any action on the steering wheel.
Move the steering from lock to lock, until there is no longer any tight spot.
Top up the level if it again goes down.
Bleed the circuit by moving the steering several timesin each direction.
Top up the level if it again goes down.
IMPERATIVE: Use new power steering fluid for both filling and topping-up the circuit.
