SPECIAL FEATURES: FORCED REGENERATION OF THE PARTICLE FILTER
Tools.
Diagnostic stations: LEXIA or PROXIA
Imperative: Respect the safety and cleanliness requirements.
Forced regeneration of the particle filter.
IMPERATIVE: Respect the safety and cleanliness requirements specific to HDi engines.
ESSENTIAL: Connect the vehicle to a gas extractor approved for this type of operation.In the absence of the required installations,carry out the forced regeneration of the particle filter outside the workshop, in a concreted
area well away from any inflammable materials. Place the vehicle in the high position.
WARNING:
Check that the fuel level is sufficient (at least 20 litres).
Start the engine and allow it to warm up (60°C minimum).
Connect the diagnostic tool to the vehicle’s central socket.
Trigger the regeneration cycle, with the diagnostic tool.
Automatic running of the regeneration cycle of the particle filter:
Autocheck by the engine ECU. Stabilisation of engine speed at
4000 rpm, operating with post injection.
Change to idling speed (for 30 seconds).
Stabilisation of engine speed at 3000 rpm, checking of the efficiency of the regeneration of the particle filter.
Change to idling speed.
NOTE:Let the engine run at idling speed for the benefit of cooling.
Stop the engine.
IMPERATIVE: Wait for at least an hour before any operation on the exhaust line.

Safety requirements.
ESSENTIAL:Given the special features of the MA type piloted
manual gearbox, observe the requirements detailed below.
IMPERATIVE: Always disconnect the battery negative terminal
before operating on the actuators.
NOTE:
After disconnecting the battery, never try to remove the clutch
actuator on the vehicle before having checked that it is in the closed
position
(rod pushed in).
IMPERATIVE:After Sales checks done with the engine running must be
performed with «Neutral»engaged and the handbrake on (unless there
is a clear mention otherwise in the repair procedures).
IMPERATIVE:The areas of movement of the clutch fork and of the gear
engagement lever must always be kept free during the actuatoroperating phases.

IMPERATIVE:When initialising the clutch actuator and/or gearbox
actuator, do not allow any person to walk or stand in front of the vehicle.
WARNING:When the engine is running, it is forbidden to perform
repairs on the clutch and gearbox actuators on the vehicle (whether
manually or using a diagnostic tool).
WARNING:Each time the driver’s door is opened and each time the
igntion is switched on, the gearbox ECU prompts the initialising of the
clutch and gearbox actuators
(there is movement of the clutch fork and
of the gear lever).
WARNING:Whether the ignition is switched on or not, an action on the
gear selector causes the clutch fork and the gear engagement lever to
move on the 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.

Features.
The piloted gearbox is a modern manual gearbox with technology that offers
enhancements in every driving situation.
The piloted manual gearbox has two operating programmes:

«Sequential»programme.
«Automatic»programme.
The piloted manual gearbox has:
A gearbox ECU
(supplier:SIEMENS). A gearbox actuator with two electric motors (supplier:SACHS).
A clutch actuator with one electric motor (supplier:SACHS).
A gearbox input speed sensor.
The piloted manual gearbox has no gear control cable and no clutch cable.Changes of gear and clutching/declutching are activated by the gearbox
actuator and the clutch actuator.
Lubrication.
Oil capacity : 2 ± 0,15 litres.
Checking of oil level : No oil level check.(*)Lubrication intervals : Lubricated «for life».
(*)= Only a visual check of the sealing at each engine oil change interval.

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).
