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».

RECOMMENDATIONS/PRECAUTIONS : AL4 AUTOMATIC GEARBOX
Precautions to be taken
Repairs on mechanical components.
Never place the gearbox on the ground without protection.
In order to avoid breaking the input shaft ring, it is imperative
that the
converter retaining bracket should be in place when handling the
gearbox.
It is imperative
to use the centring peg and the converter retaining
bracket to couple the gearbox on the engine.
After coupling the gearbox on the engine, remove the centring peg. Modification of the oil usage counter value.
Exchanging the gearbox ECU:
- Note down the gearbox counter value.
- Transfer the value read into the the new gearbox ECU.
Exchanging the gearbox:
- Initialise the oil usage counter to 0.
Draining the gearbox:
- Initialise the oil usage counter
(follow the diagnostic tool procedure).

RECOMMENDATIONS/PRECAUTIONS : AL4 AUTOMATIC GEARBOX
Procedure to be followed prior to carrying out repairs on AL4 autoactive gearbox
If a gearbox malfunction occurs, there are two possible configurations
depending on the seriousness of the fault:
- Gearbox in back-up mode with a replacement programme of
(the fault
values are taken in substitution).
- Gearbox in back-up mode with an emergency programme (3rd hydraulic).
WARNING: In the emergency programme, an impact is felt when
changing P/R, N/R and N/D.
Réception client.
Discuss with the customer, to find out all the malfunction symptoms.
Oil quality - Oil level.
Oil quality.
If the gearbox has suffered a serious fault resulting in a malfunction or
the destruction of a clutch, the oil will overheat and become
contaminated with impurities: the oil is said to be «burnt».
This is characterised by a black colour and the presence of an
unpleasant smell.
ESSENTIAL: The gearbox must be replaced.Oil level
(see corresponding operation).
An excessive oil level can result in the following consequences:
- Excessive heating of the oil.
- Oil leaks.
An insufficent level causes the destruction of the gearbox.
Top up the level of oil in the gearbox
(if necessary).
Check using a diagnostic tool.
Read the fault codes
(engine and gearbox).
Absence of fault codes.
Carry out parameter measures, actuator tests and a road test.
Presence of fault codes.
Carry out the necessary repairs.
Delete the fault codes.
Carry out a road test to check the repair and, if need be, modify the
gearbox ECU parameters
(this is essential after an initialisation of the
ECU).

RECOMMENDATIONS/PRECAUTIONS : AL4 AUTOMATIC GEARBOX
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.
