WRITE SAVED DATA
NOTESAll data must be saved with command SC003 SAVE COMPUTER DATA for this
command to be run.
Writing is carried out after the computer has been reprogrammed or replaced.
Validating this command writes the data saved using command SC003 SAVE COMPUTER DATA.
The data is as follows:
–vehicle idle speed,
–injector calibration codes (if the vehicle is fitted with IMA),
–programming of exhaust gas recirculation valve data,
–options available on the vehicle and managed by the computer (E.g. air conditioning).
This data configures the computer and prevents:
–engine malfunction after reprogramming or replacing the computer,
–incorrect interpretation of the information provided by the CLIP 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.

SAVE COMPUTER DATA
NOTESThe data is saved before computer reprogramming or the computer is replaced.
On the CLIP tool, select the SC003 Save computer data.
If the following message appears:
"a saved file exists, do you want to overwrite this data?"
(this file corresponds to the last save carried out on the tool)
Select YES.
Confirming this command saves the following vehicle-specific data:
–injector codes,
–the EGR valve data programming;
–options available on the vehicle and managed by the computer (E.g. air conditioning).
This information will be saved on the CLIP tool.
After saving has finished, use the command SC001 Enter saved data to be able to set the new computer
parameters, after programming and reprogramming.

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.
