the signal or multiplex line connection fault)
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.

–DF005 Oil pressure sensor circuit.
–DF016 Lock-up solenoid valve circuit.
–DF017 Exchanger flow solenoid valve circuit.
–DF023 Gearbox oil temperature sensor circuit.
–DF036 Pressure modulating solenoid valve circuit.
–DF131 Slipping.
–DF226 Automatic transmission internal pressure.
–DF237 Invalid coolant temperature signal.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after a road test.
Check gearbox oil grade and level.
If an operation is necessary (see MR 364 Mechanical, 23A, Automatic transmission, Filling - levels
(for Mégane II) and MR 370 Mechanical, 23A, Automatic transmission, Oil change (for Scenic II)).
Check that the water-oil exchanger is not blocked.
Measure the resistance of component 754 between the following connections:
●connection code 5BC,
●connection code 5BB.
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.
The resistance should be between:
2660 Ω < R < 2360 Ω at 20˚C and 327 Ω < R < 290 Ω at 80˚C.
If the fault 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.

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.

OIL TOO HOT SIGNAL
NOTESThere must be no present or stored faults.
This status means the oil temperature is above the normal operation temperature.
The status displays "NO" if the gearbox oil temperature is below 140 ˚C.
The status displays "YES" when the gearbox oil temperature rises above 140 ˚C.
If the correct status is not displayed, use the interpretation of fault DF177 "Automatic transmission
overheating".

EXCHANGER FLOW CONTROL SOLENOID VALVE*
NOTESThere must be no present or stored faults.
The exchanger flow control solenoid valve command status displays "ACTIVE" in the following conditions:
–gearbox oil temperature is above 100˚C,
–engine speed is greater than 2000 rpm.
With other conditions, the solenoid valve status displays "INACTIVE".
Disconnect the computer. Check the cleanliness and condition of the connectors.
Check the continuity of the following connections:
●connection code 5DD, between components 119 and 1019,
●connection code 5DN, between components 119 and 1019.
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 it.
Measure the resistance of component 1019 between the following connections:
●connection code 5DD,
●connection code 5DN.
The value should be 40 Ω ± 2 at approximately 23 ˚C.
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 it.
If the resistance is greater than 50 Ω, check the wiring harness, computer connector and modular connector.
If the status of the command fails to change, use the interpretation of fault DF017 "Exchanger flow solenoid valve
circuit".
AFTER REPAIRRepeat the conformity check from the start.
