NOTESConditions for applying the fault finding procedure to a stored fault:
The fault reappears after:
– engine speed PR055 Engine speed between idle speed and 1050 rpm,
– a coolant temperature PR064 Coolant temperature ≥ 20°C.
Priorities when dealing with a number of faults:
– DF028 Cylinder 3 injector control circuit
– DF052 Injector control circuit.
Special notes:
After an injector has been replaced, run commands SC002 Enter injector codes and
SC036 Reinitialise programming and follow the procedure.
IMPORTANT:
Cylinder no. 1 is located at the timing end.
Do not disconnect the injectors when the engine is running.
When removing and refitting an injector, respect the cleanliness guidelines and safety
advice (see MR364 (Mégane II ph2), MR370 (Scénic II ph2), MR 395 (Laguna II
ph2), 402 (Vel Satis ph2), 405 (Espace IV ph2), Mechanical, 13B Diesel injection,
