1.DEF: Above maximum 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 DF026 CYLINDER 1 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).

This fault appears when the computer detects a fault on the injector control section
Check the condition of the injector connectors (see Wiring Diagram Technical Note, Mégane II ph2, Scénic II
ph2, Component codes 193, 194, 195, 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.
Check the continuity and insulation of the following connections:
– Connection code 3KW between components 193 and 120.
– Connection code 3CR between components 193 and 120.
– Connection code 3KX between components 194 and 120.
– Connection code 3CS between components 194 and 120.
– Connection code 3KY between components 195 and 120.
– Connection code 3CT between components 195 and 120.
– Connection code 3KZ between components 196 and 120.
– Connection code 3CU between components 196 and 120.
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, contact the Techline.
