PARTICLE FILTER SAFETY AND CLEANLINESS REQUIREMENTS
General.
ESSENTIAL: Given the very high pressures prevailing in the fuel high pressure circuit (1600 Bars), respect the following regulations.
It is forbidden to smoke in the immediate proximity of the high pressure circuit during a repair.
Avoid working close to flames or sparks.When the engine is running:
Do touch the fuel high pressure circuit.
Always keep out of range of possible projections of fuel, which could cause serious injuries.
Do not place your hand near to any leak on the fuel high pressure circuit. After the engine has stopped, wait 30 seconds before starting any operation.
NOTE:The waiting time is necessary to allow the fuel high pressure circuit to return to atmospheric pressure.
Safety rules.
IMPERATIVE:Wait at least an hour before starting any repair on the exhaust line.
Forced regeneration of the particle filter:
Check that there are no aerosols or inflammable products inside the vehicle’s boot.
Wear high temperature gloves.
Connect the vehicle to a gas extractor approved for this type of operation.
IMPERATIVE: 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.

PARTICLE FILTER SAFETY AND CLEANLINESS REQUIREMENTS
Operations on the fuel additive circuit.
IMPERATIVE: For all operations on the additive circuit, wear protective goggles and gloves that are resistant to hydrocarbons.
The work area must be ventilated.
In the event of any significant dispersion of additive:
Wear a breathing mask for filtering the particles.
Recover as much of the product as possible.
Place the product thus recovered in an appropriately labelled container. Wash the soiled area with copious amounts of water.
Dispose of materials and solid residues in an authorised recovery point.
IMPERATIVE:The filling kit should be recycled following a repair. All «Eolys» additive containers that have been opened should be
disposed of.
Cleanliness rules.
ESSENTIAL: The operator should wear clean overalls.
Before working on the injection circuit, it may be necessary to clean the unions of the following sensitive components(see corresponding operations).
Fuel filter.
Fuel high pressure pump.
Fuel high pressure regulator.
Fuel high pressure common injection rail. Fuel high pressure piping. Diesel injector carriers.
IMPERATIVE: After dismantling, immediately blank the unions of the sensitive components with plugs, to prevent any ingress of impurities.

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.

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).
