If the fault found is caused by the converter lockup, use the interpretation of fault DF016 "Lock-up solenoid valve
circuit".
If the fault comes from the engaged gear, carry out fault finding on the multifunction switch.
Check that statuses ET123, ET124 and ET125 operate correctly.
–ET123 "Multifunction switch S2".
–ET124 "Multifunction switch S3".
–ET125 "Multifunction switch S4".
Check the multifunction switch settings.
AFTER REPAIRRepeat the conformity check from the start.

GEAR LEVER UNLOCKING
NOTESThere must be no present or stored faults.
This status displays "ACTIVE" when the gear lever is locked and "INACTIVE" when the gear lever is unlocked.
Check the status with:
–Gear lever in position "P".
–Instrument panel displaying "P" for the gear lever position.
Depress the brake pedal; the message on the instrument panel: Depress the brake pedal disappears.
The status displays "INACTIVE" with the brake pedal depressed and gear lever unlocking permitted.
The status displays "ACTIVE" with the brake pedal released and the gear lever locked in position "P".
This status can only be checked with the gear lever in position "P".
If the correct status is not displayed, use the interpretation of fault DF095 "Selector lever lock electromagnet
circuit".
AFTER REPAIRRepeat the conformity check from the start.
Make sure that shifting up and down through each gear works properly.

Refer to the procedure and the safety instructions for carrying out a setting point check on the torque converter.
Theoretical engine speed at setting point: 2300 ± 150 rpm
Is the value of the setting point wrong or is there an internal noise in the converter?
Carry out a road test, observing the engine speed
on the instrument panel and the information
displayed on the diagnostic tool (PR006 Engine
speed)Replace the torque converter, the lock-up solenoid
valve and the oil. If the oil is burnt, also 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)).
When replacing the torque converter, ensure that the
reaction shaft is securely attached to the hub of the
oil pump (flanged shaft).
Note:
A setting point which is too low may be due to a lack
of engine power. Does the engine speed change each time
there is a gear change?
The checks carried out have not provided any
evidence of a fault and the automatic
transmission appears to be working correctly.
If the vehicle does show the customer complaint
selected, continue with the entire fault finding
procedure.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)).
