NOTESPriorities when dealing with a number of faults:
Deal with fault DF012 Sensor feed no. 2 voltage first, if it is present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present following a road test or an actuator control AC002 EGR
Solenoid Valve.
Special notes:
If the fault is present:
– there is smoke from the exhaust,
– the EGR function is deactivated.
If CO.0 and/or CC.1 is still present, the OBD warning light will come on after three
consecutive driving cycles (starting + 5 seconds + switch off the ignition and wait
40 seconds).
Use bornier Elé. 1681 for any work on the computer connectors.
CO.0
NOTESNone.
Check the EGR valve connections.
Check the injection computer connections.
Repair if necessary.
Check the continuity and insulation from earth of the following connections:
Injection computer, brown 48 track connector B track J2 Track 6 EGR valve
Injection computer brown 48-track connector B, track F4 Track 2 EGR valve
Repair if necessary.
Measure the resistances of the EGR valve between:
–tracks 2 and 4. If the resistance of the EGR valve is not between 2.4 kΩ and 5.6 kΩ, replace the EGR valve.
–tracks 2 and 6. If the resistance of the EGR valve is not between 1.9 kΩ and 6.4 kΩ, replace the EGR valve.
–tracks 4 and 6. If the resistance of the EGR valve is not between 0.8 kΩ and 3.8 kΩ, replace the EGR valve.
If the fault is still present, replace the EGR valve.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.

Special notes:
The EGR and turbocharging functions are inhibited.
The level 1 warning light comes on.
If CC.0 is still present, the OBD warning light will come on after three consecutive
driving cycles (starting + 5 seconds + switch off the ignition and wait 40 seconds).
Use bornier Elé. 1681 for all operations on the injection computer connectors.
WARNING
If dealing with this fault requires the EGR valve to be replaced, run command RZ002 EGR Adaptives
described in Interpretation of commands in this section.
CC.1
NOTESNone.
Check the EGR valve connections.
Check the injection computer connections.
Repair if necessary.
Measure the resistance of the EGR solenoid valve between tracks 1 and 5.
If the resistance is not approximately 8 Ω ±0.5 at 20°C, replace the EGR valve.
Check the continuity and insulation against + 12 V of the following connection:
Injection computer brown 48-track connector B, track L2 Track 5 of the EGR valve
Repair if necessary.
If the fault is still present, replace the EGR valve
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after:
– replacing injector(s),
– replacing the injection computer.
Special notes:
If the fault is present:
– the engine speed is limited,
– the level 1 warning light is lit.
1.DEF
NOTESNone.
Program the injector codes using command SC002 Enter injector codes.
Carry out the procedure described in the Interpretation of commands section.
If the fault is still present, after the ignition is switched off and dialogue is established, contact the Techline.
2.DEF
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 Injector code use changes to YES or FAULTY, fault DF276 will be present, and
the engine will operate in defect mode.
– Program the injector codes using:
command SC002 Enter injector codes, (follow the procedure described in the Interpretation of commands
section).
– After the codes have been entered:
– switch off the ignition,
– wait until power latch closes down and then switch the ignition back on,
– establish dialogue and clear the fault memory,
– end of operation.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.
