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.

SPECIAL FEATURES: PARTICLE FILTER / CHECKING THE ADDITIVE PUMP
Sealing of the additive injector.
Couple tool [1] to the tube (1).
Action the manual pump [1].
WARNING:The additive injector should open at a pressure of 100 ± 20 Bars.
Action the manual pump in vacuum
[1]at 800 m.bars.
WARNING:The downstream pressure should not fall rapidly.
NOTE:Replace the fuel tank if the injector is defective.
Couple the tube
(1).
Operate the actuator test «Filling the tube: additive pump – additive injector», with the aid ofLEXIAor PROXIA.
Check the additive level.
The checking of the additive level is done with reference to the gradations «a»marked on the additive
reservoir.
The top graduation indicates maximum filling
(3 Litres).
The difference between the two gradations equates to 0,25 Litres.

Refitting.
Place the pedal in the high position (contact at “a”).
Attach the cable yoke on the hook of the clutch pedal.
Fit a new clip
(3).
Fit the endpiece (4)to the bulkhead (fit with G6grease).
Clip the endpiece (5)on the gearbox.
Couple the cable to the lever (1).
Depress the clutch cable several times to lodge the cable in place.
Check that the endpiece (4) is correctly lodged on the bulkhead.
Check the operation of the automatic adjusting system.
After fitting the cable, pull the clutch lever in the inverse direction
(direction F), the lever should
move back when pulled by hand.
Press the clutch pedal very lightly and repeat the same operation. The lever should not move
back.
WARNING:If a system blockage is detected when checking, or if the pedal has been removed,
the pedal position must be adjusted. The correct positioning of the pedal is obtained by the
angular displacement of the stop supports
"a"and "b".

Adjusting the pedal height.
Loosen the nut (6)and the screw (7).
Using a lever, raise the stop support (8)to its highest position. In this position, there should be a substantial free
play in the pedal.
Lower the support until there is a free play of
2 ± 1 mm.
Tighten the nut (6) and the screw (7).
Check that the clutch cable sleeve can move freely.
At rest, the clutch cable sleeve should be free and able to lengthen and shorten.
Clutch pedal travel.
The automatic clutch wear adjustment system has no manual adjustment.
Pedal travel is identical on all models:154 ± 5 mm.
The adjustment is achieved by reducing the length of the cable sleeve.
WARNING:Automatic adjustment of the pedal travel is accompanied by a modification of the curvature of the
cable sleeve. Do not add any supplementary fixing points or alter the routing in any way.

RECOMMENDATIONS PRECAUTIONS: MA PILOTED MANUAL GEARBOX
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.

GEARBOX
TRANSMISSION
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.
