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.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This test enables the condition and the conformity of the engine wiring harness to be
checked.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.

– Connect a test light between connection 3JB of component 898 and a chassis earth.
– Run command AC063 Thermoplunger no. 1 relay.
If the test light comes on correctly, measure the thermoplunger resistance between the connection 3JA of
component 898 and a chassis earth.
If the resistance is greater than 2Ω, replace thermoplunger 1.
If the test light does not come on, check the continuity and insulation of the following connection:
– Connection code 3JB between components 1550 and 898.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the earthing on the additional heater interface unit:
– Disconnect the connector of component 1550.
– Connect a test light between connections 3JA and BP27 of component 1550.
– Run command AC063 Thermoplunger no. 1 relay.
If the test light comes on correctly, replace the additional heater interface unit.
If the test light does not come on, check the continuity and insulation from + 12 V of the following connection:
– Connection code 3JA between components 120 and 1550.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
