IMMOBILISER CODE PROGRAMMED
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
YES
Status ET341 becomes YES if dialogue is established between the UCH and the
injection computer and the card code is recognised.
The engine is only authorised to start if the code is recognised by the UCH computer and
status ET003 Engine immobiliser is INACTIVE.
The code remains NO if dialogue between the UCH and the injection computer is not
possible. Status ET003 Engine immobiliser is ACTIVE.
The cause of the malfunction may be due to the incorrect programming of the cards,
(see 97B, Passenger compartment connection unit, configuration and
programming); follow the card programming procedure.
If the malfunction is not due to the card codes, test the multiplex network (when fault
finding is carried out for functions) and check that there is dialogue between the UCH,
the Protection and Switching Unit and the injection computer.
If dialogue is not established, contact the Techline.

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.

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.
