NOTESThere must be no present or stored faults.
Check gearbox oil grade and level.
If an oil change or top-up is necessary see the Draining-Filling-Levels section of the Workshop Repair Manual.
Check that the gearbox is not leaking oil.
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.
Use the Universal bornier Elé. 1681 to check the insulation, continuity and the absence of interference
resistance on the following connections:
●Connection code 5DA between components 119 and 1017.
●Connection code 5DB between components 119 and 1017.
●Connection code 5BX between components 119 and 754.
●Connection code 5BA 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 it.
Measure the resistance of component 1017 between the following connections:
●Connection code 5DA.
●Connection code 5DB.
The value should be approximately 300 Ω ± 40 Ω at a temperature of approximately 20 ˚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 not correct, either the sensor or the harness is damaged. Replace the faulty component.
Measure the resistance of component 754 between the following connections:
●Connection code 5BX.
●Connection code 5BA.
The value should be approximately 1 Ω ± 0.2 Ω at 20 ˚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 value is not correct, the solenoid valve or the electric/hydraulic interface harness is damaged.
AFTER REPAIRRepeat the conformity check from the start.

Carry out a converter stall test.
Follow the procedure in the Converter stall test section of the Workshop Repair Manual.
See the Taking line pressure section of the Workshop Repair Manual.
Set up the pressure gauge for a line pressure reading.
Warm engine with gearbox oil temperature between 60 and 80 ˚C.
Take the line pressure readings under the following conditions:
–with the gear lever in P or N and engine speed at 2000 rpm the pressure should be between 2.6 and 3.2 bar.
–with the gear lever at R and engine speed at 2000 rpm, the pressure should be above 4 bar.
–with the gear lever in D and engine speed at 2000 rpm, the pressure in first gear should be greater than 7 bar.
If the values are not correct, there is a fault inside the gearbox.
If the fault is still present, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

NOTESOnly refer to Customer complaints after carrying out a complete fault finding
procedure with the diagnostic tool and the conformity check.
If the engine races when shifting from 1/2 when cold (automatic transmission oil
temperature lower than 15˚C), replace the pressure modulating solenoid valve
(EVM).
Use the diagnostic tool to check the
consistency between the display and the gear
lever positions (ignition on and engine
stopped).Adjust the control settings following the instructions
provided (see MR 370, Mechanical, 23 A,
Automatic Transmission, Automatic
transmission control unit (for Mégane II and
Scénic II)).
Are they consistent?
Check the oil level and the condition of the oil
(colour, odour, etc.).Replace the automatic transmission (see MR 364,
Mechanical, 23A, Automatic transmission,
Removal-Refitting (for Mégane II) and MR 370,
Mechanical, 23A, Automatic transmission,
Removal-Refitting (for Scénic II)). Does the condition of the oil suggest there
is an internal fault in the automatic
transmission?
With the engine stopped, check the line
pressure information provided by the pressure
sensor (PR003 Oil pressure).Replace the pressure sensor (see MR 364,
Mechanical, 23A, Automatic transmission,
Pressure sensor (for Mégane II) and MR 370,
Mechanical, 23A, Automatic transmission,
Pressure sensor (for Scénic II)). Is the value higher than 0.2 bar?

Check the oil level.
Check the oil pressure value using PR003 Oil pressure:
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 bars.
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.
Do the recorded values correspond to the specified values?
Shift the gear lever into position D and monitor
PR007 Turbine speed when accelerating.Replace the pressure modulating solenoid valve and
the oil. Repeat the check after replacement.
If the fault is still present, replace the hydraulic
distributor and all the solenoid valves (see MR 364
Mechanical, 23A, Automatic transmission,
Hydraulic distributor (for Mégane II) and MR 370
Mechanical, 23A, Automatic transmission,
Hydraulic distributor (for Scénic II)).
Does the turbine speed change?

Replace the automatic transmission (see MR 364, Mechanical, 23A,
Automatic transmission, Removal-Refitting (for Mégane II) and
MR 370, Mechanical, 23A, Automatic transmission, Removal-Refitting
(for Scénic II)).
