1.DEF: Above max threshold
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– engine speed is between idling speed and 1050 rpm PR055 Engine speed,
–PR064 Coolant temperature ≥ 50°C.
Priorities when dealing with a number of faults:
Apply the interpretation of faults DF027 CYLINDER 2 INJECTOR CONTROL
CIRCUIT and DF249 Injector control first if they are present or stored.
Special notes:
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.
After an injector has been replaced, run command SC002 Enter injector codes and
command SC036 Reintialise programming and follow the procedure.
IMPORTANT
Possible absence of combustion on one cylinder even though the injector is properly
fed.
Cylinder no. 1 is located at the timing end.
Do not disconnect the injectors when the engine is running.
When removing or refitting an injector, follow the cleanliness and safety instructions
(see MR 364 (Mégane) or 370 (Scénic), Mechanical, 13B, Diesel injection, Diesel
injector: Removal - Refitting).

DF060 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.
If the fault is present:
– remove the injector concerned,
– if there is no obvious fault in the way the injector has been fitted (notably the injector washer), swap the injector
with another from the engine.
– Run commands SC002 Enter injector codes and SC036 Reintialise programming and follow the procedures.
– Restart the engine.
– If the injector concerned produces another combustion misfire in its new position, replace it.
If the fault is stored:
check that no customer complaint has been declared; clear the fault and carry out a road test.
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).
