NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
– there is smoke coming from the exhaust,
– the EGR offset fault finding function is disabled,
– the OBD warning light illuminates after three consecutive driving cycles (starting
+ 5 seconds + switch off the ignition and wait 1 minute).
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
Priorities when dealing with a number of faults:
–DF012 Sensor supply voltage no. 2 if it is present or stored.
IMPORTANT
This fault can result in a rapid and significant fouling of the particle filter.
If dealing with this fault requires the EGR valve to be replaced, run command SC036
Reinitialise programming and select EGR valve to reinitialise the EGR valve offsets
(see Replacement of components).
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.
