NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after:
– with the engine running,
– a road test.
Special notes:
If the fault is present:
– engine torque limited for CO,
– engine stops for CO on more than one injector,
–the level 2 warning light comes on for CC and 1.DEF,
–the level 1 warning light comes on for CO,
–the European On Board Diagnostic warning light is lit.
– engine cut-off for CC and 1.DEF.
Use bornier Elé.1681 for all operations on the engine management computer.
After replacing an injector, run commands SC002 Enter injector codes and SC036
Reinitialisation of programming, follow the described procedures.
IMPORTANT
Cylinder no. 1 is located on the engine flywheel end.
Please observe the cleanliness guidelines and safety advice.

Check the condition of the injector no.4 connector (see Wiring Diagram Technical Note, Mégane II ph2, Scénic
II ph2, component code 196).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Disconnect injector no. 4.
Measure the resistance of injector no. 4.
Replace the injector if it has a short circuit (R = 0 Ω) or open circuit (infinite resistance measurement).
Otherwise, reconnect injector no. 4.
Check for continuity and the absence of interference resistance of the following connections:
– Connection code 3KZ between components 120 and 196.
– Connection code 3CU between components 120 and 196.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
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.
