Carry out a conformity check to detect any possible faults.
Check the setting point of the converter (see MR 364 Mechanical, 23A, Automatic transmission, Checking the
setting point of the converter (for Mégane II and Scénic II)
If the setting point value is not correct, carry out the following checks:
–Check the oil pressure using PR003 Oil pressure:
–Warm engine with gearbox oil temperature between 65 and 90˚C.
–Take the line pressure reading under the following 3 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 bars.
–gear lever in D position, the pressure reading in first gear must be greater than 5.5 bars.
3Engine speed at 2200 rpm:
–gear lever in R position, the pressure reading must be greater than 11 bars.
–gear lever in D position, the pressure reading in first gear must be greater than 11 bars.
If the line pressure value read under one of these 3 conditions is incorrect, replace the line pressure sensor.
If the line pressures recorded under these 3 conditions are good, then the pressure sensor is operating correctly.
Replace the pressure regulating solenoid valve.
If the fault is still present after the pressure regulating solenoid valve has been replaced, replace the hydraulic
distributor and during refitting, take into account Technical Note 4194A Automatic transmission indicator strip
flashing for the adjustment of the ball detent blade.
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 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.

Carry out a test on the multiplex network (see 88B Multiplex).
If the fault is still present, run fault finding on the Anti-lock braking and Electronic stability program systems
(see 38C, Anti-lock braking system).
AFTER REPAIRDeal with any other faults. Clear the fault memory.

NOTESRun fault finding on the injection system and check that it is
operating correctly.
Deal with all other faults first.
Conditions for applying the fault finding procedure to stored faults:
Safe mode is triggered after a fault, not by the driver.
To check that there are no faults with the turbine speed sensor, apply the interpretation of fault DF038 Turbine
speed sensor circuit.
To check that there are no faults with the vehicle speed signal, apply the interpretation of fault DF048 Vehicle
speed signal.
Carry out a conformity check to detect any possible faults.
If the fault is still present, a brake or clutch in the gearbox is certainly defective.
Contact 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.
