INLET AIR TEMPERATURE
NOTESThere must be no present or stored faults.
Perform this fault finding procedure after noting an inconsistency in the Parameters
menu.
Check the air flow sensor.
Check the injection computer connections.
Repair if necessary.
Check for + 12 V on track 4 of the air flow sensor connector.
Display PR059 Inlet air temperature and check that the value displayed is not recovery value 20 °C.
If this is the case, check the coolant temperature sensor:
Injection computer brown 48-track connector B,
track G2Track 1 of the air flow sensor connector
Injection computer brown 48-track connector B,
track E2Track 2 of the air flow sensor connector
Repair if necessary.
Measure the resistance between tracks 1 and 2 of the air temperature and pressure sensor.
Replace the air temperature and pressure sensor if the resistance is not:
3,714Ω ±161Ω at 10 °C
2,448Ω ±96Ω at 20 °C
1,671Ω ±59Ω at 30 °C

FUEL TEMPERATURE
NOTESThere must be no present or stored faults.
NOTE
In the event of a relatively low outside temperature, the difference between the
fuel temperature and the engine temperature after cold starting may be greater
than 30 °C.
Check in the Fuel circuit tab in PR063 Fuel temperature that the value displayed is not the recovery value 100 °C.
If it is, check the fuel temperature sensor:
Check that the fuel temperature sensor is in good condition:
Repair if necessary.
Check the continuity and the absence of interference resistance on the following lines:
Brown 48-track connector B, track H2 Track 1 fuel temperature sensor
Grey 32-track connector C, track F1 Track 2 fuel temperature sensor
If the temperature read is inconsistent, check that the sensor follows the resistance as a function of temperature
calibration curve (NTC) correctly.
Replace the fuel pressure and temperature sensor if the resistance is not:
2,051 ± 123Ω at 25 °C
810 ± 47Ω at 50 °C
309 ± 17Ω at 80 °C
Replace the fuel temperature sensor if it is incorrect (an incorrect sensor is often the result of an electric shock).
AFTER REPAIRRepeat the conformity check from the start.

menu.
Display the PR064 Coolant temperature and check that the value displayed is not recovery value -30°C.
If this is the case, check the coolant temperature sensor:
Check the condition of the coolant temperature sensor connections.
Repair if necessary.
Check for the absence of interference resistance on the following lines:
Brown 48-track connector B, track F2 Track 3 coolant temperature sensor
Brown 48-track connector B, track H1 Track 2 coolant temperature sensor
If the temperature read is inconsistent, check that the sensor follows the resistance as a function of temperature
calibration curve (NTC) correctly.
Replace the air temperature and pressure sensor if the resistance is not:
2,252Ω ± 112Ω at 25 °C
811Ω ±39Ω at 50 °C
283Ω ±8Ω at 80 °C
Replace the coolant temperature sensor if the values read do not correspond to the ones above.
AFTER REPAIRRepeat the conformity check from the start.

WRITE SAVED DATA
NOTESAll data must be backed up with command SC003 Backup computer data for this
command to be run.
Writing is carried out after the computer has been reprogrammed or replaced.
Confirming this command writes the data backed up using command SC003 Backup computer data.
The data is as follows:
– Vehicle-specific idle speed.
– Options available on the vehicle and managed by the computer (Example: Air conditioning).
– Injector calibration codes (if the vehicle is fitted with IMA).
– Programming of exhaust gas recirculation valve data.
They will configure the computer and will enable it to avoid:
– engine malfunction after reprogramming or replacing the computer,
– faulty interpretation of information provided by the CLIP tool.
AFTER REPAIRRestart the conformity check from the beginning.

ENTER INJECTOR CODES
NOTESThis command is carried out after the replacement of the injectors, and only if the
vehicle is configured with IMA (ET104 Injector code use YES).
If this command is not run, the fault DF276 Injector code programming will be
present.
IMPORTANT
Letters Q and J, and figures 0 and 9 are not used in IMA codification.
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.
– 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.
– Exit fault finding mode.
– Switch off the ignition and wait 30 seconds.
– Switch the ignition back on and check for faults.
–The DF276 Injector code programming should be stored.
If the fault is still present, the command has not been run correctly.
Start the procedure again and follow the instructions.
Switch off the ignition.
If all these checks still do not enable the command to be confirmed, contact the Techline.
AFTER REPAIRRestart the conformity check from the beginning.

SAVE COMPUTER DATA
NOTESThe data is saved before computer reprogramming or the computer is replaced.
Selecting this command saves the following vehicle-specific data:
– 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 (Example: Air conditioning).
This information will be saved in the CLIP tool.
●Before replacing or reprogramming the computer:
–Select SC003 SAVE COMPUTER DATA.
– if the following message appears: backup file exists, do you want to overwrite it?:
(this file corresponds to the last save carried out on the tool)
Select YES.
When the save has been performed, replace the computer or carry out the programming then proceed to the next
step.
Once the backup is complete, run the command SC001 Write backed up data to reconfigure the computer.
AFTER REPAIRRestart the conformity check from the beginning.

EGR ADAPTIVES
NOTESThis command is only performed after the exhaust gas recirculation valve has been
replaced.
Deal with all faults which do not involve the exhaust gas recirculation valve before
programming the valve.
After replacing the exhaust gas recirculation valve, clear the valve offsets from the memory.
Procedure to be followed after replacing the exhaust gas recirculation valve:
– Switch on the ignition.
– Run command RZ002.
– Once the command has terminated, check that the following parameters and statuses correctly indicate the
statuses below:
–PR128 EGR valve first offset = 0 %
–PR129 EGR valve last offset= 0 %
–PR088 EGR valve position feedback= 0 %
– When the command has finished, switch off the ignition and exit fault finding mode.
–Wait 30 seconds, and switch on the ignition again.
– Switch off the ignition again and wait 30 seconds.
– Refer to the following parameters again:
– PR128 EGR valve first offset: 15 % < X < 30 %
– PR129 EGR valve last offset: 15 % < X < 40 %
– If the parameters are not correct, refer to the interpretation of DF272 EGR valve control circuit
–Otherwise
– Start the engine.
– Let the engine idle for 1min, accelerate to 2,500 rpm for 5 seconds and return to idle speed.
– Repeat this procedure 5 times.
Check the faults.
If the fault does not recur, end the fault finding procedure.
If the fault recurs, restart the procedure after disconnecting and reconnecting the valve.
If the fault is still present, replace the EGR valve.
AFTER REPAIRRestart the conformity check from the beginning.
