LOWER SEQUENTIAL LEVER SWITCH
NOTESThere must be no present or stored faults.
This indicates the status of the lower sequential lever switch.
This status displays "ACTIVE" with the gear lever in position "M-".
This status displays "INACTIVE" with the gear lever in a position other than "M-".
Check the sequential lever supply on the following connections:
●check for + 12 V on connection AP43 of component 129,
●check for the vehicle earth on connection N of component 129.
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.
With the gear lever in position "M", measure the voltage of the following connections:
●check for the vehicle earth on connection 5H of component 129,
●check for the vehicle earth on connection 5FM of component 129.
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 any of the measured values is + 12 V, replace the sequential lever.
If the values are 0 V, check that the gear lever positions match the instrument panel display.
If the correct status is not displayed, use the interpretation of fault DF093 "Manual sequential controls circuits".
AFTER REPAIRRepeat the conformity check from the start.
Make sure that shifting up and down through each gear works properly.

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".

NOTESNone.
Try the diagnostic tool on another vehicle.
Check:
–the connection between the diagnostic tool and the diagnostic socket (connection and cable in good condition),
–the power supply to the computer,
–the engine and passenger compartment fuses.
Check that the CLIP sensor is supplied by connections BP32, MAN and NAM of component 225, displayed when
both red indicator lights on the sensor illuminate.
Make sure that the CLIP sensor is connected to the computer's USB port.
Make sure the CLIP sensor is communicating properly with the vehicle's computers; this can be seen by the two
green diodes on the sensor lighting up.
Check the following connections on component 225:
●connection code AP43 (+ after ignition feed),
●connection code BP32 (+ battery feed),
●connection code MAN (earth).
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.
Disconnect the automatic transmission computer connector to check the insulation, continuity and the absence
of interference resistance of the following connections:
●connection code AP4, between components 119 and 1337,
●connection code BP42, between components 119 and 1337,
●connection code N, between components 119 and 107,
●connection code 3MT, between components 119 and 120,
●connection code 3MS, between components 119 and 120,
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.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

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 less 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)).

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)).

NOTESOnly refer to Customer complaints after carrying out a complete fault finding
procedure with the diagnostic tool and the conformity check.
Run a multiplex network test (see 88B, Multiplex).
Check for the following parameters:
–PR135 Standard pedal position,
–PR136 Raw pedal position.
Carry out a road test using the diagnostic tool, making sure that status ET013 Gear engaged operates normally.
If the customer complaint occurs with the brake pedal released, check that status ET004 Brake light switch
(Closed) is NO.
If not, adjust the brake light switch and the brake pedal.
Make sure that the instrument panel display of the gear engaged matches the gear lever position.
Check the automatic transmission wiring harness (sequence solenoid valve control).
Replace it if necessary.
Check that the gear lever cable is working properly and adjust it if necessary.
Check that the multifunction switch is working correctly.
If the fault is still present, contact Techline.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
