STOREDCOMBUSTION MISFIRING ON CYLINDER 3
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 DF042 Cylinder 3 injector circuit first, if it is present or stored.
Check that the IMA code of injector no. 3 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.
Consult the interpretation of commands, SC002 Entering injector codes.
Check the engine compression.
Repair if necessary.
Check the valve clearance and adjust if necessary.
When dealing with several combustion misfire faults, check the conformity of the fuel by applying test 10 Diesel
fuel conformity check.
Visually inspect the return pipe of injector no. 3.
Repair if necessary.
If the fault is still present, carry out test 8 INCORRECT INJECTOR OPERATION.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

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 DF043 Cylinder 4 injector circuit first, if it is present or stored.
Check that the injector no. 4 IMA code 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.
Consult the interpretation of commands, SC002 Entering injector codes.

2.DEF: Parameter at max limit
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault becomes present:
–the engine is started with a speed greater than 1750 rpm and a fuel flow greater than
30 mg/st,
–a road test.
Special notes:
If the fault is present:
–particle filter regeneration is inhibited,
–the vehicle performance is reduced,
–the level 1 warning light is illuminated.
IMPORTANT
This fault can result in a rapid and significant fouling of the particle filter.
Apply TEST 3 Turbocharged air inlet circuit check.
Check the turbine upstream temperature sensor connections.
check the engine management computer connections.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
