ACTIVE
OR
INACTIVEIf the brake lights are working:
check the continuity and make sure there is no interference resistance on the following
connection:
Connection code 5A between components 160 and 120/645/119.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the brake lights are not operational, check:
– the condition and fitting of the brake switch,
– the condition and conformity of the brake light fuse,
– the conformity of the values in the following table:
disconnect the switch and carry out the following checks:

PR038
RAIL PRESSURE
NOTESPerform this fault finding procedure:
– after the interpretation of fault DF053 Rail pressure regulation function,
– after an inconsistency for PR038 noted in the Parameters menu,
– after the interpretation of the fault finding procedure for AC011 Rail pressure
regulator,
– following a customer complaint (starting faults, poor performance, stalling, etc.).
Check the continuity and the absence of interference resistance on the following connections:
Injection computer, brown 48-track connector
B, track G3Track 2 of the rail pressure sensor connector
Injection computer brown 48-track
connector B, track A4Track 3 of the rail pressure sensor connector
Injection computer, brown 48-track connector
B, track C4Track 1 of the rail pressure sensor connector
If all these connections are correct, check for fuel pressure sensor power supply:
+ 5 V Track 3 of the rail pressure sensor connector
Earth Track 1 of the rail pressure sensor connector
Repair if necessary.
Check the sealing of the low and high-pressure diesel circuits (visual inspections, odour) pump housing,
overpressure valve, pipes, rail and injector unions, injector wells, etc.
If all of the previous checks are correct, switch the ignition on, wait for more than 1 minute and display PR038 Rail
pressure.
If the value is less than 50 bar, the rail pressure sensor is correct. If it is greater than this value, replace the rail
pressure sensor and tighten it to 35 ± 5 Nm.
AFTER REPAIRRepeat the conformity check from the start.

COOLANT TEMPERATURE
NOTESNo fault should be present or stored:
Perform this fault finding procedure after noting an inconsistency in the Parameters
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.

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.

ALP 7 Oil leaks from the turbocharger
NOTESBefore dealing with this customer complaint, check that there are no faults,
and the conformity (or otherwise) of the parameters and statuses using
the diagnostic tool.
If the customer complaint is not eliminated, perform the following checks.
Check the area around the turbocharger
Note:
An oil leak does not correspond always to a turbocharger fault, the oil leak can arise from the area around
the turbocharger.
Depending on the vehicle type, the best visual access will be either from above or from below.
1-Do not start the engine.
Check the area around the turbocharger and identify the origin of the leaks.
Clean the oil traces on the turbocharger.
2- Start the engine and let it warm up for several minutes.
IMPORTANT
If the air filter was removed previously, refit it before starting the engine (risks foreign matter entering the air inlet
circuit).
Accelerate with no load several times, progressively increasing the duration before releasing the accelerator
pedal.
Visually inspect the exterior condition of the fuel supply pipes and the turbocharger oil return and the area
around it.
Identify the origin of the leaks.
Is an oil leak present at the air compressor inlet or outlet?
YES
NO
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

Run test 3 Turbocharger control solenoid valve check
Is the vehicle equipped with a particle filter?
NO
Start the engine and warm it up at idle speed for
10 minutes.
IMPORTANT
If the air filter was removed previously, refit it before
starting the engine (risks foreign matter entering
the air inlet circuit).
Perform several rapid and brief accelerations under
no load.
Note:
The presence of smoke is often normal.
The quantity, density, colour and persistence
of the smoke are the important factors.
Is the exhaust outlet producing abnormal
smoke?
YES
Consult test 4 Turbocharger.
YES
Perform the fault finding of the "particle filter"
function, refer to the TESTS or corresponding
ALP.
NOThe turbocharger is not faulty. Another engine
fault is probably present. Consult the TEST
or the corresponding ALP.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
