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 selector lever positions match those displayed on the instrument panel.
Repair if necessary.
If the correct status is not displayed, use the interpretation of fault DF093 Manual sequential controls circuits.
If the fault is still present, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

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).
●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 it.
No communication on line K
Check the continuity, insulation and absence of interference resistance on line K of the diagnostic socket.
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.

ALP3 Automatic transmission operating faults
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?

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.
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, replace the multifunction switch.
Carry out fault finding on the injection system.
Check engine speed signal PR006 during a road test at a steady speed.
If the signal is wrong, replace the engine speed sensor.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
