NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present following a delay of 5 seconds, with the engine running,
the vehicle stationary with a gear engaged and a difference of more than 384 rpm
between the engine speed and the turbine speed.
Special notes:
Use bornier Elé. 1681 for all operations on the computer connectors.
Use the Mégane II or Scénic II wiring diagram Technical Note.
Check the oil level in the engine and gearbox.
Top up if necessary (see MR 364 Mechanical, 23A, Automatic transmission, Filling-levels (for Mégane II) and
MR 370 Mechanical, 23A, Automatic transmission, Draining-Filling (for Scénic II)).
Check the engine speed:
–Possible engine speed instability
–Deal with the faults displayed on the diagnostic tool for the injection computer.
Deal with the other faults first.
Check the turbine speed:
–Possible inconsistency with the turbine speed,
–Possible turbine sensor fault,
–Possible solenoid valve oil pressure fault.
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.

following connections:
●connection code 5AU, between components 119 and 754,
●connection code 5DM, between components 119 and 754.
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 754 between the following connections:
●connection code 5DM,
●connection code 5AU.
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 solenoid valve or the electric/hydraulic interface wiring harness if the resistance is not 40 Ω ± 2
at 23˚C.
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
