Operations on electrical components.Do not disconnect:
The battery when the engine is running.
The ECU with the ignition switched on.
The clutch and gearbox actuators with the ignition switched on.
When carrying out electrical checks: The battery must be correctly charged.
Never use a voltage source higher than 16V.
Never use a lamp to supply an actuator directly.
Before disconnecting connector, check: The condition of the various contacts (for deformation, corrosion, etc).
The presence and the status of the mechanical unlocking.
Driving the vehicle.
IMPERATIVE:
Never move the vehicle with the ignition switched off.
Never push the vehicle to attempt to start it
(impossible with a piloted
manual gearbox).
Towing.
Conditions for towing.
It is necessary to lift the front of the vehicle to tow it, after having
positioned the gear lever in neutral. If there is a gearbox fault or
malfunction, the vehicle can remain immobilised depending on theseriousness of the fault.
If a gear is engaged,the conditions for immobilisation of the
vehicle are:
Combustion engine stopped (the engine should not be started).
The clutch is open (clutched).
In these conditions are met, you can lift the front of the vehicle to tow it.
If it should not be possibe to lift the front of the vehicle, there are
ways to unblock it:
Engage «N», using a diagnostic tool.
Engage «N», without using a diagnostic tool.

RECOMMENDATIONS PRECAUTIONS: AL4 AUTOMATIC GEARBOX
Engines: KFV NFU RFN RHZ
If a gearbox malfunction occurs, there are two possible
configurations depending on the seriousness of the fault:
Gearbox in backup mode with a replacement programme of
(the
fault values are taken in substitution).
Gearbox in backup 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).
