NOTESConditions for applying the fault finding procedure to stored faults:
If the fault appears following a road test during which the quality of the gear changes
deteriorates.
Disconnect the battery.
Disconnect the gearbox computer. Check the cleanliness and condition of the connectors.
Disconnect the engine management computer. Check the cleanliness and condition of the connectors.
If the fault is still present, run fault finding on the injection system (see 17B, Petrol injection or 13B, Diesel
injection).
Repair if necessary.
Run a multiplex network test (see 88B, Multiplex).
If the problem is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

NOTESIf the following faults are present or stored, deal with them first:
–DF003 Sensor feeds.
–DF005 Oil pressure sensor circuit.
–DF023 Gearbox oil temperature sensor circuit.
–DF036 Pressure modulating solenoid valve circuit.
–DF244 Turbine speed sensor signal
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after a road test.
Check the gearbox oil grade and level (see MR 364 Mechanical, 23A, Automatic transmission, Filling - levels
(for Mégane II) and MR 370 Mechanical, 23A, Automatic transmission, Oil change (for Scénic II)).
Check that the gearbox is not leaking oil
To locate the cap position, consult MR 364, Mechanical, 23A, Automatic transmission, Line pressure
measurement (for Mégane II) and MR 370, Mechanical, 23A, Automatic transmission, Line pressure
measurement (for Scénic II)).
Check the oil pressure with the engine switched off using PR003 Oil pressure: if the pressure is greater than
0.2 bars, replace the pressure sensor.
●Warm engine with gearbox oil temperature between 65 and 90˚C.
●Measure the line pressure under the 3 following conditions:
IMPORTANT
The vehicle must be stationary: handbrake on and brake pedal depressed, no accessories operating (e.g.:
air conditioning)
1engine speed idling:
Shift the gear lever to R, N and D, the pressure reading must be greater than 2.5 bar.
2engine speed at 1200 rpm:
–gear lever in R position, the pressure reading must be greater than 4 bar.
–gear lever in D position, the pressure reading in first gear must be greater than 5.5 bar.
3engine speed at 2200 rpm:
–gear lever in R position, the pressure reading must be greater than 11 bar.
–gear lever in D position, the pressure reading in first gear must be greater than 11 bar.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault appears when the engine is running and the gear lever is at P.
Special notes:
Use bornier Elé. 1681 for all operations on the computer connectors.
Disconnect the battery.
Disconnect the modular connector and check the cleanliness and condition of the connections.
Disconnect the computer. Check the cleanliness and condition of the connections.
Repair if necessary.
Check the insulation, continuity and the absence of interference resistance to earth, to + 12 V of the following
connections:
●connection code 5DA, between components 119 and 1017,
●connection code 5DB, between components 119 and 1017.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring. Otherwise replace the wiring.
Reconnect the modular connector.
Measure the resistance of component 1017 between the following connections:
●connection code 5DA,
●connection code 5DB.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring. Otherwise replace the wiring.
Replace the sensor or the wiring harness if the resistance is not: 300 Ω ± 40.
If the problem is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
