GEARBOX
TRANSMISSION
RECOMMENDATIONS PRECAUTIONS: MA PILOTED MANUAL GEARBOX
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).

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.
A pedal initialisation.
A reinitialisation of the autoadaptives.
A programming
(if necessary).
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.

NOTE:The vehicle is equipped with the «shift lock»«P».
Two switches placed on the gear control gate permit the driver to choose one of the following
three driving programmes:

Normal programme: Operates as the default programme (eco law, autoadaptive mode).
Sport programme (a): Permits a more dynamic, sporty performance.
Snow programme (b): Facilitates starting and adhesion on slippery surfaces.
To return to the normal programme, press a second time on the sport switch or snow switch.

ELECTRICAL
SYSTEM
CHARGING CIRCUIT ALTERNATOR WITH MONOFUNCTION REGULATOR
Checking the alternator output.
Connect as shown in the diagram opposite, using an ammeter (A), a voltmeter (V),
and a rheostat
(R)or a Volt/Ammeter/Rheostat combination.
Referring to the vehicle’s equipment specification
(see table opposite), adjust the
engine speed and rheostat charge to obtain
U = 13.5 V.
Reminder:The excitation energising current will flow through the warning lamp;
check that the warning lamp comes on when the ignition is switched on. It shouldgo out when the engine has started
(accelerate slightly).
Checking the voltage regulator.
Set the rheostat to zero and disconnect all the electrical consumers.
Display
3000alternator rpm. If U alternator is > 14.7 V, the regulator is faulty.
Note:These tests should be performed with the engine hot and the battery fully
charged.
Method of reading the alternator speed.
Fit a reflecting shim on the pulley of the alternator.
Adjust a stroboscope to the frequency equivalent to the control speed.
(e.g. 2000 rpm = 2000/60 = 83 Hz).
Adjust the engine speed so that the shim appears fixed.

Checking the compressor oil level (Continued)
2/ Slow leak.
Slow leaks do not lead to oil loss, therefore the same procedure should be followed as if there was no leak at all.
3/ Fast leak.
This type of leak causes both oil loss as well as allowing air to enter the system.
It is therefore necessary to:
Replace the dehydrator.
Drain as much oil as possible
(when replacing the faulty component).
Either before or during filling of the system with
R 134.afluid, introduce 80 ccof NEWoil into the system.
