NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present, engine performance is reduced and engine instabilities may
occur.
Priority when dealing with a number of faults:
Deal with fault DF040 Cylinder 1 injector circuit first, if it is present or stored.
Check that the IMA code for injector no. 1 has been entered correctly and that it matches the code marked on
the corresponding injector.
Enter the code to the unprogrammed/incorrectly programmed injector, if necessary.
Refer to the interpretation of command SC002 Enter injector codes (see Interpretation of commands).
Check the engine compression.
Repair if necessary.
Check the valve clearance and adjust if necessary.
When dealing with a number of misfiring faults, check the fuel conformity by running test 11 Diesel fuel
conformity check.
Visually inspect the return pipe of injector no. 1.

diagnostic tool.
If the customer complaint is not eliminated, perform the following checks.
Is it difficult or impossible to start the engine?
PART A:
Check the engine earths.
Ensure that the engine speed reaches 250 rpm with the starter motor, as displayed on the parameter screen (PR055
Engine speed).
If the engine speed is less than 250 rpm, refer to Technical Note 6014A, Checking the charging circuit.
If the engine speed shown on CLIP is zero and the engine is running, check the resistance of the engine speed
sensor between connections 3BG and 3BL of component 149:
Replace the sensor if its resistance is not 510 Ω < X < 850 Ω at 20°C
Check the continuity of the following connections:
– connection codes 3BG and 3BL between components 120 and 149.
Check the conformity of the engine earths (oxidation, tightness, etc.).
Check the mounting, the gap (if necessary refer to the information in the workshop repair manual for the vehicle) and
the condition of the sensor (overheating).
Replace if necessary.
Check the synchronisation of the camshaft sensors and the engine speed sensors with the display of ET238
Synchronisation.
If synchronisation is not active, refer to the checks described in DF195 Camshaft/engine speed consistency.
check the fuel circuit sealing.
If the fault is still present, see DF053 Rail pressure regulation function 2.DEF, step 4.
Check that the heater plugs are actuated using the AC001 Preheating unit command.
Check the sealing and condition of the inlet circuit: run Test 4 Turbocharged air inlet circuit check and follow the
associated fault finding procedure.
Check that there are no foreign bodies on the flowmeter grille: run Test 5 Air flowmeter and follow the associated
fault finding procedure.
Check the position of the exhaust gas recirculation valve.
Check that the exhaust is not blocked: run Test 1 Exhaust pipe check and follow the associated fault finding
procedure.
Check the consistency of the signal from the engine coolant temperature sensor.
Check the operation of the pressure regulator (see AC011 Rail pressure regulator).
Check the operation of the injectors (excessive return leak, clogging, seizing): run Test 9 Poor injector operation.
Check the engine timing (and the position of the high pressure pump sprocket).
Check the balance of the compressions, according to the power consumption during the starting phase
(Compression test menu on the CLIP Technic tool or using a compression gauge)
after the operation, clear the faults caused by disconnecting the regulator and the heater plugs.
End of part AImpossible
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

flow sensor circuit, 2.DEF), the engine coolant temperature sensor (run DF001 Coolant circuit, 1.DEF), and
the engine speed (run DF195 Engine speed / camshaft sensor consistency, 2.DEF).
Check:
– That the diesel filter is not clogged (for the test, see DF053 Rail pressure regulation function 2.def).
– That there are no leaks on the high and low pressure diesel circuits, run Test 4 Turbocharged air inlet circuit
check.
