To enable the particle filter to clean itself automatically, as soon as possible drive at an average speed of 48 mph (80 km/h), depending on
– road conditions,
– and observing authorised speed limits.
Drive until the warning message disappears or the special particle filter warning light on the instrument panel extinguishes.
See the vehicle Driver's Handbook to optimise regeneration when driving.

NOTES
Conditions for applying fault finding procedures 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:
– the level 1 warning light is lit,
– the OBD warning light will illuminate after three consecutive driving cycles (starting + 5 seconds + switching off the ignition and waiting 1 minute),
– the particle filter fault finding procedure is inhibited, – particle filter regeneration is inhibited,
Priorities when dealing with a number of faults:
Deal with fault DF011 Sensor feed no. 1 voltage first if it is present or stored.

PRESENT OR STORED
NOTES
Conditions for applying fault finding procedures to stored faults:
The fault occurs during after-sales regeneration using the diagnostic tool when the particle filter upstream temperature is less than 450 °C.
Special notes:
If the fault is present, particle filter regenerations are not possible.
Use the Elé. 1681 bornier for all operations on the engine management computer connector.
The oxidation catalytic converter does not produce enough heat at the particle filter inlet to regenerate the particle filter.
Replace the catalytic converter, then run command SC017 Particle filter regeneration. If the fault is still present, contact the Techline.
AFTER REPAIR Deal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

1.DEF: Multiplex line connection fault
NOTES
Conditions for applying the fault finding procedure to stored faults:
The fault appears when the engine is running.
Special notes:
If the fault is present:
– the level 1 warning light is lit,
– the OBD warning light will illuminate after three consecutive driving cycles (starting + 5 seconds + switching off the ignition and waiting 1 minute).
Run a multiplex network test (see 88B, Multiplex).
If the fault is still present, run fault finding on the Automatic transmission system (see 21A, AUTOMATIC
TRANSMISSION).
AFTER REPAIR Deal with any faults.

CO.0 : Open circuit or short circuit to earth CC.1 : Short circuit to + 12 V
1.DEF: Above maximum threshold 2.DEF: Below minimum threshold
NOTES
Conditions 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 is lit.
IMPORTANT
The fault can appear after the alternator has been saturated for too long.
For a stored fault, clear the fault + switch off the ignition and wait 1 minute + road test to confirm the fault before any operations.
Run a multiplex network test (see 88B, Multiplex).
If the fault is still present, check the insulation and continuity on the following connection:
Injection computer, connector C, track A3 Alternator, track 2, black connector Repair if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIR Deal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

NOTES
Conditions for applying fault finding procedures to stored faults:
The fault is declared present after a road test.
Special note:
If the fault is present:
– the EGR and turbocharger functions are inhibited, – the level 1 warning light is lit.
Use bornier Elé. 1681 or Elé. 1590 for any operation on the injection computer connectors.
IMPORTANT
This fault can result in a rapid and significant fouling of the particle filter. If the EGR valve needs to be replaced to resolve the fault, all faults must then be cleared.
Check the EGR valve connections. Check the injection computer connections. Repair if necessary.
If the fault is still present, run command SC036 Reset programming and select EGR valve to reset the EGR valve offsets.
(see Replacement of components)
If the valve is jammed or irrevocably seized, replace the EGR valve.
WARNING
A programming procedure is required when the EGR valve is replaced.
The EGR valve initial offset and EGR valve last offset parameters must be reinitialised. Refer to the Replacement of components section to carry out this programming.
