STOREDCOMBUSTION MISFIRING ON CYLINDER 2
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 DF041 Cylinder 2 injector circuit first, if it is present or stored.
Check that the IMA code of injector no. 2 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. 2.
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.

OR
STOREDIMPACT DETECTED SIGNAL
1.DEF : Impact stored by the injection computer
NOTESConditions for applying the fault finding procedure to stored faults:
Only apply the procedure if the fault is present and if the vehicle does not start.
Special notes:
The fault appears when the injection computer receives a frontal impact signal from the
Airbag computer via the multiplex network.
As soon as the injection computer receives this signal:
–engine operation is prohibited,
–the level 2 warning light is lit.
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
If the vehicle has been involved in an accident:
Carry out any necessary repairs,
–clear the fault,
–switch off the ignition,
–wait for 1 minute,
–switch on the ignition,
If the fault does not recur, end the fault finding procedure.
If the fault recurs, carry out fault finding on the AIRBAG computer.
If the vehicle has not been involved in an accident:
Run fault finding on the AIRBAG computer
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

STOREDCLUTCH SWITCH CIRCUIT
1.DEF : No signal
2.DEF : Inconsistent signal
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after the clutch pedal is depressed, or during a road test.
Special notes:
If this fault is present, the cruise control/speed limiter function will be inhibited.
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This check enables the condition and the conformity of the engine wiring harness to be checked.
Check the conformity and adjustment of the clutch switch (position, connection).
–display status ET405 Clutch pedal switch:
–when the clutch pedal is engaged, status ET405 should be INACTIVE,
–when the clutch pedal is disengaged, status ET405 should be ACTIVE.
If these checks are not OK, replace the clutch switch.
If the check show the correct results:
Check the connections of the clutch pedal switch.
Check the injection computer connections.
Repair if necessary.
Check continuity and make sure there is no interference resistance on the following connection:
Injection computer black 32-track connector A,
track C4Track 1 clutch pedal switch
Repair if necessary.
Check for the presence of earth on track 2 of the clutch pedal switch.
Repair if necessary.
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.
