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 with the diagnostic tool.

PRESENT
OR
STOREDINJECTOR No. 1
1.DEF: Internal electronic fault
NOTESPriorities when dealing with a number of faults:
– DF026 Cylinder 1 injector control circuit.
Conditions for applying the fault finding procedure to a stored fault:
If the fault becomes present after:
– the engine is started,
– a road test.
IMPORTANT:
– cylinder no. 1 is located at the timing end,
– observe the cleanliness guidelines and safety advice,
– do not disconnect the injector connections with the engine running as this may
damage the engine.
Special notes:
If the fault is present:
– reduced driving pleasure,
– injector is not controlled or incorrectly controlled.
Use bornier Elé.1681 for all operations on the engine management computer.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
Apply Test 10 Poor injector operation.

CONTINUED
Check the condition of the injector no. 1 connector (see Wiring Diagram Technical Note, Laguna II ph2, Vel
Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 193).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Vehicle, 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.
Check the continuity and absence of interference resistance of the following connections:
•3KW between components 120 and 193,
•3CR between components 120 and 193.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
If the fault is still present, contact the Techline.
