1.DEF : Valve jammed open
2.DEF : Valve jammed closed
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 deactivated if several faults with DF226 Damper valve circuit are
present.
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 Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
Check the EGR valve connections.
Check the injection computer connections.
Repair if necessary.
Check the continuity and the absence of interference resistance on the following connections:
Injection computer brown 48-track connector B, track C2 Track 1 EGR valve connector
Injection computer brown 48-track connector B, track D2 Track 5 EGR valve connector
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 (pipes pierced or damaged) and that the clamps are properly
tightened.
Measure the resistance of the EGR valve motor between tracks 1 and 5.
If the resistance displayed is not between 1
Ω < X < 400Ω at 20˚C, replace the EGR valve.
If the valve is jammed or irrevocably seized, replace the EGR valve.
Run command SC036 Reset programming and select EGR valve to reset 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.

Carry out the procedure described in the Interpretation of commands section.
If the fault is still present after switching off the ignition, waiting for 1 minute and then re-establish dialogue,
Follow the interpretation of command SC002 Entering injector codes.
If the fault is still present, contact the Techline.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present when the ignition is switched on or with the engine
running.
Special notes:
If the fault is present, the level 1 warning light comes on.
IMPORTANT
The fault can appear after the alternator has been saturated for too long.
For stored faults, clear the fault, switch off the ignition and wait for 1 minute before
carrying out a road test to confirm the fault before any operation.
Run a multiplex network test (see 88B, Multiplexing).
If the fault is still present, check the insulation and continuity on the following connection:
Injection computer, connector C, track A3Alternator, Track 2, black connector
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.

(see Replacement of components).
Check the EGR valve connections.
Check the injection computer connections.
Repair if necessary.
