1.DEF : Inconsistency of the signal
2.DEF : Multiplex line connection fault
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present during a road test.
Special notes:
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
Check the ABS computer connections.
Check the injection computer connections.
Repair if necessary.
Run fault finding on the multiplex network, (see 88C, Airbags - seat belt pretensioners) and the ABS, (see 38C,
Anti-lock braking system).
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.

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.

Between components 120 and 1589.
Check the continuity, the absence of interference resistance, and the insulation to earth of connection 3ABS
between components 120 and 1589.
Check for earth on connection 3ABT of the turbine upstream temperature sensor
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing

Otherwise, replace the turbine upstream temperature sensor.
If the fault is still present, contact the Techline.
