EGR PROGRAMMING CUT-OFF
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
NONE
No EGR cut-off, the EGR valve is working properly in accordance with the
computer programs.
Switch off the ignition and wait 1 minute.
Switch the ignition on and check for faults.
Check the engine battery voltage with the engine stopped and then running.
If no faults are present or stored, restart the vehicle and test at idle speed.
Do not accelerate too much and reach an engine speed that is too high.
Accelerate above idling speed for a few seconds.
Check that the clutch pedal (ET405 Clutch pedal switch) is not pressed and that the
vehicle has stopped completely.
Test the present and stored faults and repair.
Reinitialise the EGR offsets by consulting the interpretation of command
SC036 Reinitialisation of programming and select EGR valve".
Allow the engine to heat up until this cut-off disappears.
Check that the regeneration of the particle filter in progress has completely finished.
Allow the engine to cool until this cut-off disappears.
Too low atmospheric pressure, the EGR valve is disabled.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

ENTER INJECTOR CODES
NOTESThis command should be run after the injectors have been replaced and only if the
vehicle has been configured with IMA.
(ET104 USE OF INJECTOR CODES to YES).
If this command is not performed, the DF276 INJECTOR CODE PROGRAMMING
fault 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 at the engine flywheel end.
Procedure to be followed:
–Read the 6-character alphanumeric codes etched 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 appear in neither the Current column nor the Desired column, check the codes read and
make sure 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 is still present, the command has not been performed correctly.
Start the procedure again and follow the instructions.
If the codes are still not recognised, check whether the computer's standby has been correctly set:
Switch off the ignition and wait for 1 min.
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.

TURBOCHARGING SOLENOID VALVE
NOTESThis command is used to check the turbocharging circuit.
This command checks that the turbocharger and the control circuit are working properly.
Introduction
1-Check the sealing of the high pressure air circuit:
Pipes not joined or pierced, pressure sensor disconnected or poorly fitted (seal present), intercooler pierced.
To test the intercooler: stabilise the engine speed between 3,500 and 4,000 rpm with the vehicle stopped and
check that there are no leaks.
Check the resistance of the turbocharging limitation solenoid valve between tracks 1 and 2.
Replace the solenoid valve if its resistance is not 15.4 Ω ± 0.7 at 20˚C.
Check the injection computer connections.
Check for continuity and make sure there is no interference resistance on the following connection:
Injection computer grey 32-track connector C,
track E1Track 1 turbocharging solenoid valve
Repair if necessary.
Check for the presence of + 12 V after relay on track 2 of the turbocharging solenoid valve.
2 - Turbocharger control circuit check
–With the engine stopped, make sure that the control rod is in the resting position.
–Start the engine and make sure that the control rod actuates to the upper stop.
–(when the engine is switched off, the control rod should return to the rest position)
–If the control rod does not move correctly, carry out the following checks:
1) Vacuum pressure command check:
–Disconnect the solenoid valve inlet hose and connect it to a pressure gauge.
–Start the engine and run it at a stable idle speed.
–If the vacuum pressure does not reach 800 mbar ± 100: check the vacuum pressure circuit from the vacuum
pump.
–Stop the engine, reconnect the inlet hoses and go to step no. 2.
2) Solenoid valve control check:
–Disconnect the solenoid valve outlet hose.
–Start the engine and run it at a stable idle speed.
–Place your hand on the solenoid valve and block the outlet union with your thumb.
–If you notice no solenoid valve vibration, check the operation of the computer output (step 5). Solenoid valve
operation check:
–Connect the pressure gauge to the solenoid valve outlet union.
–Start the engine and run it at a stable idle speed.
If the vacuum pressure does not reach 800 mbar ± 100, replace the solenoid valve.

CONTINUED
Turbocharger control circuit check (continued)
4) Turbocharger operation check:
a) Connect a vacuum pump to the hose connected to the turbocharger control diaphragm.
Apply a negative pressure of 800 ± 100 mbar:
If there is a leak, replace the turbocharger (diaphragm included).
b) Check the control rod movement and setting (see MR 364, Mechanics, 12B, Turbocharging).
If the control rod is sticking, replace the turbocharger.
c) Engine cold and stopped:
Remove the turbocharger inlet duct and check that the compressor turns freely on the axis.
d) If the fault persists:
Check that the exhaust manifold is not leaking.
Check that the exhaust is not blocked.
Carry out the necessary repairs.
5) Computer output stage check: (solenoid valve connected).
This operation can only be carried out if the checks indicated in step no. 2 are not conclusive.
Either with the voltmeter: Connect the voltmeter earth lead on track 2 of the solenoid valve and the positive
lead on track 1.
Clear any solenoid valve fault then run command AC004:
●The voltmeter should display ten cycles of two successive voltages ~ = battery voltage X opening cycle ratio*
in process.
that is: ~ 2.5 V (opening cyclic ratio* of 20%) then ~ 8.7 V (opening cyclic ratio* of 70%).
Or with the oscilloscope (at 5 V range/division and 1 ms/div time base): Connect the earth lead of the
oscilloscope to the battery earth and the positive test pin to track 2 of the solenoid valve.
Clear any solenoid valve faults, then run command AC004:
●the oscilloscope should display a square wave signal of 12.5 V in amplitude at a frequency of 140 Hz
(with an opening cyclic ratio* passing from ~ 20 to ~ 70%).
If the measurement is correct, replace the solenoid valve.
If the measurement does not show any control or continuous voltage, contact the Techline.

DAMPER VALVE
NOTESThis command allows you to check the operation of the damper valve.
–Measure the resistance of the damper valve solenoid valve between tracks 1 and 2.
Replace the solenoid valve if the resistance is not: 46 ± 3 Ω at + 25˚C.
–Check for continuity and for the absence of interference resistance on the following connections:
Injection computer, brown 48-track connector
B, track M1track 1 of the damper valve solenoid valve
connector
+ 12 V after relaytrack 2 of the damper valve solenoid valve
connector
A) Engine running at idle speed
Make sure that there is a pressure of ~ 900 mbar on the solenoid valve inlet hose.
Make the necessary repairs (pressure circuit conformity and seal).
B) With the vehicle ignition on, engine stopped
Make sure the damper valve is open.
If not, clean or replace the air vent unit.
Disconnect the solenoid valve inlet and outlet hoses,
Connect a vacuum pump to the inlet union and apply a pressure of ~900 mbar
If there is a leak, replace the solenoid valve.
Run command AC012.
Otherwise, with the solenoid valve connected, check operation of the computer output stage with a voltmeter:
Voltmeter earth cabletrack 1 of the solenoid valve
Voltmeter positive leadtrack 2 of the solenoid valve
Clear any solenoid valve faults,
Run command AC012.
The voltmeter should display ten ON-OFF cycles (8.75 V then 2.5 V).
If the measurement is correct, replace the solenoid valve.
If the measurement does not show any lights, contact the Techline.
C) Vehicle with ignition off
Connect a vacuum pump to the flap control diaphragm and apply a pressure of ~900 mbar:
If the diaphragm does not maintain the negative pressure, replace the air vent unit (the diaphragm cannot be
disconnected).
If the diaphragm maintains the vacuum and the flap does not operate, clean or replace the air vent unit.
If the diaphragm maintains the underpressure and the valve operates, then operate it several times to ensure
that there is no blockage.
Check for clogging of the air vent unit and its valve, and clean if necessary.
