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.

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.

AIRCONAIRCON
AIR CONDITIONING SYSTEM R 134.a
Testing procedure
Conditions inside the vehicle.
Positions of the air conditioning controls:
Maximum cold.
Maximum blower power.
Air distribution on
«ventilation»with the air vents open.
Position the air inlet flap to outside air.
WARNING:For RFTA (1), disconnect the air inlet motor connector, first
ensuring that it is in the outside air position.
(1) RFTA= Fully automatic air conditioning.
Test procedure.When all these conditions are met, proceed in the following order:
Measure the temperature in the workshop approx. one metre in front of
the vehicle’s air inlet grille.
Start the engine
(without the air conditioning, or the blower, operating)and wait for the cooling fan slow speed to trigger (should the engine tem
perature not rise sufficiently, it is permissable to increase the engine
speed to 2000 rpm)
.
Once it is sufficiently hot in the engine compartment, return the engine
to idle and commence the test.Switch on the air conditioning and adjust the engine speed to
2500 rpm.
In an ambient temperature of 40°C, the engine speed will be brought
down to 2000 rpm, in order for the pressure safety threshold to cut off the
compressor.
For further temperatures/pressures: see Tables and Graphs on following
pages
221, 222 and 226.
After
3 minutesof operation, note down the following 3 parameters:
The temperature of the blown air coming out of the 2 central air vents
(take the average).
The high pressure, via the intermediary of the clickfit union (at the
pressure reducer inlet).
The low pressure, via the intermediary of the clickfit union (at the pressure
reducer outlet).NOTE:The low and high pressures are absolute pressures.
When measuring the blown air temperatures, avoid any contact between
the thermocouple and the air vents.
