NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after a road test.
Special notes:
The EGR function is inhibited if several faults are present with DF226 Damper valve
circuit.
If 1.DEF is present:
– the level 1 warning light is lit,
– the vehicle performance is reduced,
– there is smoke coming from the exhaust.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
1.DEF
2.DEF
NOTESNone
Check the EGR valve connections.
Check the injection computer connections.
Repair if necessary.
Check the continuity and absence of interference resistance of the following connections:
– connection code 3VP,
– connection code 3VQ.
between components 120 and 1460.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check that there are no leaks on the EGR circuit, pierced or damaged pipes, and the tightness of the clips.
Measure the resistance of the EGR valve motor between connections 3VP and 3VQ.
Replace the EGR valve if the resistance displayed is not between 1 Ω < X < 400 Ω at 20°C.
If the valve is jammed or irrevocably seized, replace the EGR valve.
Run command SC036 Reinitialise programming and select EGR valve to reinitialise the EGR valve offsets (see
Replacement of components).
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

NOTESCondition for applying fault finding ONLY to a present fault:
The fault is declared present after:
– reprogramming the injection computer,
– replacing and programming the injection computer.
Special notes:
If the fault is present:
– the engine speed is limited,

NOTESNone
Enter the injector codes using command SC002 Enter injector codes (see Interpretation of commands).
If the fault is still present after switching off the ignition, waiting 1 minute and then re-establishing dialogue.
Refer to the interpretation of command SC002 Enter injector codes.
If the fault is still present, contact the Techline.
Otherwise clear the fault memory using RZ007 Fault memory.

NOTESThis fault appears on any blank computer (new or recently
reprogrammed)
WARNING
A computer without the IMA option can be replaced by a computer with this option. The codes are not
saved during command SC003 Save computer data.
In this case, status ET104 “Use of injector codes” becomes “YES”, fault DF276 is present and the engine
operates in defect mode.
