STATUS DEFINITIONStatuses ET742 to ET751 correspond to the causes of the regeneration request. They
are associated with parameters PR816 "Stored regeneration start No. 1" to PR825
"Stored regeneration start No. 10" which contain the record of the vehicle mileage at
the start of regeneration (eg. PR745 "Stored regeneration start No. 4" is associated
with "ET709 Stored regeneration request status no. 4").
NOTESSpecial note:
These statuses should only be interpreted for ALP9: Particle filter warning light
comes on too frequently.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80 °C
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

Regeneration has been requested following an estimate of the maximum weight of soot
in the particle filter, without the particle filter warning light coming on.
STATUS3Request by distance travelled
Regeneration has been requested as the distance travelled since the last successful
regeneration has reached the maximum authorised value (the particle filter warning
light has not come on).
STATUS4Request by number of failed regenerations or soot weight
This status corresponds to the appearance of DF312 "Speed request".
This corresponds to the maximum number of failed regenerations or to the maximum
weight of soot in the particle filter, with the particle filter warning light coming on.

These parameters are used so that the history of the last ten regeneration failures when driving are known.
For VDIAG 58, 18, 1C:
Each parameter from PR784 to PR793 records the mileage when the particle filter warning light comes on which
is associated with DF312 Speed request.
Each time the particle filter warning light comes on, the vehicle mileage is stored in the following parameter
(PR+1).
When all ten parameters have a value other than zero and the particle filter warning light is illuminated again, the
mileage information for PR784 is cleared and replaced by the new value.
For VDIAG 5C and 20
Each parameter from PR784 to PR793 contains a record of the vehicle mileage when the particle filter warning
light illuminates. The appearance of fault DF312 Speed request is associated with each of these parameters.
PR784 to PR793 operate through successive feedback (when the particle filter warning light comes on, the value
of PR784 is copied to PR785, the value of PR785 is copied to PR786 and so on).
When there are more than ten records, the value of PR793 is overwritten. The new mileage is allocated to PR784.
If none of the parameters between PR784 and PR793 is available in the sub-function, this means than nothing
has been recorded. The parameters appear in the sub-function when they have a value above zero.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

NOTESSpecial notes:
Interpret these parameters only for ALP9 Particle filter warning light comes on too

These parameters are used so that the history of the last ten activations of the particle filter warning light are

For VDIAG 58, 18 and 1C
Each parameter between PR816 and PR825 contains the vehicle mileage when particle filter regeneration starts
when driving. Each parameter is connected with a "Rege* request status record". They are recorded
simultaneously (for example, PR819 is associated with ET745 Rege* request status record no. 4).
Each new recorded value is saved under the next PR (PR+1).
When all ten parameters have a value other than zero, and a new regeneration starts when driving, the mileage
information for PR816 is cleared and replaced with the new value.

(ET104 Injector code use to YES).
If this command is not run, fault DF276 Injection code programming will be present.
WARNING
The letters J and Q, and figures 0 and 9 are not used in IMA coding.
If these characters are used the entry will be invalid.
Cylinder no. 1 is the cylinder located on the engine flywheel end.
Procedure to be followed:
– Make a note of the 6-character alphanumeric codes engraved on the upper section of the injector bodies.
– Use command SC002.
– Select the cylinder number for the cylinder concerned in the Desired, column, then confirm.
– enter the injector code displayed for the cylinder.
– Enter the new codes for each cylinder, then confirm.
– When the command is completed, the modified codes appear in the Current column.
– Check that the codes correspond to those read earlier.
– If the codes entered do not appear in either the Current column or the Desired column, check the codes read
and make sure that the data has been entered correctly.
The possible confusions are:
digit "1" with the letter "i"
figure 8 with the letter b
figure 5 with the letter s
- Exit fault finding mode.
- Switch off the ignition and wait for 1 min. Switch the ignition back on and check for faults.
-DF276 Injector code programming should be stored.
If fault DF276 Injector code programming is present, the command has not run correctly.
Start the procedure again and follow the instructions.
If the codes are still not accepted, check that the computer has been put on standby correctly:
Switch off the ignition and wait for 1 minute.
if the warning light flashes when the ignition is switched off, the computer has not been put on standby and the
command will be ignored.
If all these checks still do not enable the command to be confirmed, contact the Techline.

RAIL PRESSURE REGULATOR
NOTESthis command is used to check:
– the operation of the pressure regulator,
– and the high pressure injection circuit.
Step 1:
Measure the resistance of the pressure regulator between connections 3HI and 3FB.
- Replace the regulator if its resistance is not 2.5 Ω < X < 3.5 Ω at 20°C.
Check the continuity and absence of interference resistance of the following connections:
– connection code 3HI,
– connection code 3FB.
Between components 120 and 11 0 5.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If, when running command AC011, you can hear a slight whistling noise and a clicking noise from the pressure
regulator, go to step 2. Otherwise, check that the computer output stage is functioning correctly:
→Using a voltmeter:
With the solenoid valve connected, connect the voltmeter earth lead to connection 3HI of component 1105 and
the positive lead to connection 3FB (Laguna II and Mégane II) or 3FB1 (Scénic II). Clear any fuel pressure
solenoid valve faults, then run command AC011:
The voltmeter should display two successive voltages: ~2.5V for an OCR* of 20%, then ~8.75V for an OCR* of
70% (ten cycles)
→Or using an oscilloscope (range 5 V/division and time base 1 ms/division):
With the solenoid valve connected, connect the oscilloscope earth to the battery earth and the positive test pin to
connection 3HI of component 11 05; clear any fuel pressure solenoid valve faults then run command AC011:
The oscilloscope should display a square wave signal of 12.5 V in amplitude at a frequency of 185 Hz (with an
OCR* passing successively from 20 to 70%).
if the measurement is correct, replace the regulator.
If the measurement is not correct, contact the Techline.
