Fault finding – Interpretation of faults13B
DF065
CONTINUED
DF065 appears on the diagnostic tool when the engine management computer has detected a fault during the
combustion phase several times in succession.
Several components may be responsible:
– the piston rings,
– the piston,
– the valves,
– the injector,
– the heater plug sealing.
Check that the stored injector codes are consistent with those engraved on each injector. If not, run command
SC002 Enter injector codes, and follow the procedure.
When dealing with a number of misfiring faults, check the fuel conformity by running test 11 Diesel fuel
conformity check.
Check the engine compressions.
Carry out the necessary repairs.
If the fault is still present, apply test 10: Incorrect injector operation.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.

STOREDIMPACT DETECTED SIGNAL
1.DEF: Impact stored by the injection computer
NOTESConditions for applying the fault finding procedure to stored faults:
Only apply the interpretation of this fault if the fault is present and the vehicle will not
start.
Special notes:
The fault appears when the injection computer receives a frontal impact signal from the
Airbag computer via the multiplex network.
As soon as the injection computer receives this signal:
– engine operation is prohibited,
–the level 2 warning light is lit.
Use bornier Elé. 1681 or Elé. 1590 for any operation on the injection computer
connectors.
If the vehicle has been involved in an accident:
Carry out any necessary repairs,
– clear the fault,
– switch off the ignition,
–wait for 1 minute,
– switch on the ignition.
If the fault does not reappear, end of fault finding procedure.
If the fault recurs, run fault finding on the AIRBAG computer.
If the vehicle has not been involved in an accident:
Run fault finding on the AIRBAG computer (see 88C, Airbag and pretensioner).

If the fault is stored, clear the fault from the computer memory.
– Switch off the ignition and wait for the diagnostic tool message (maximum time 8minutes) Communication
lost with computer: EDC16 C36, check the tool connection and computer power supply before switching
the ignition back on.
Start the engine and re-establish dialogue.
This fault may be linked to a write error following disconnection of the battery when the computer was in the
process of writing to the EEPROM phase (computer memory).
If this is the case, loading a new calibration will remove the fault.
If a more recent calibration is available, load this calibration on to the computer.
If the fault is still present:
– use the command RZ034 Computer memory,
– Switch off the ignition and wait for the computer dialogue lost message,
– switch on the ignition again,
– define the injector codes using the control SC002 Enter injector codes.
– Run the programming commands (See configuration and programming),
– switch off the ignition and wait for the message loss of communication with the computer.
Perform a road test to reinitialise the vehicle parameters.
