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).
●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.
●Connection code 3HK between components 119 and 225.
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 fault is still present, contact the Techline.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

ALP2 Engine starting faults
NOTESOnly refer to Customer complaints after carrying out a complete fault finding
procedure with the diagnostic tool and the conformity check.
Make sure that the diagnostic tool report, gear lever positions and instrument panel all indicate the same gear
engaged.
Adjust the gear lever cable if it is faulty.
The engine will only start when the gear lever is in the P or N position.
Check the battery charge and the condition of the terminals (oxidation).
Check the multifunction switch mounting and that it is working.
Check the gear lever control cable and adjust if necessary (see MR 364 Mechanical, 23A, Automatic
transmission, Filling-Levels (for Mégane II) and MR 370 Mechanical, 23A, Automatic transmission,
Draining-Filling (for Scénic II)).
Ensure that the ignition switch is working properly.
Check the power circuit of the starter relay and the starter.
Carry out fault finding on the injection system.
If the engine still doesn't start, 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 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?
