REFERENCE PRESSURE
NOTESThere must be no present or stored faults.
The reference pressure is determined by the automatic transmission computer.
Check the reference pressure on the diagnostic tool:
–engine not running: pressure reading 21 bar.
–engine at idle speed (~ 700 rpm) and selector lever at D or R: pressure reading ~ 2.7 bar.
–engine speed ~ 1400 rpm and gear lever at D or R: pressure reading ~ 8.9 bar.
AFTER REPAIRRepeat the conformity check from the start.

DIFFERENCE BETWEEN REFERENCE PRESSURE AND OIL
PRESSURE
NOTESThere must be no present or stored faults.
The reference pressure values are stored in the transmission computer memory and depend on how the vehicle
is used.
The oil pressure is regulated according to the reference pressure. The oil pressure values must always be close
to the reference pressure.
This parameter is the difference between parameter PR138 Reference pressure and parameter PR003 Oil
pressure.
–engine not running: reference pressure reading 21 bar.
oil pressure reading = 0 bar.
–engine at idle speed (~ 700 rpm) and selector lever at D or R: reference pressure reading ~ 2.7 bar.
oil pressure reading = ~ 2.6 bar.
–engine speed ~ 1400 rpm and selector lever at D or R: reference pressure reading ~ 8.9 bar.
oil pressure reading = ~ 8.7 bar.
AFTER REPAIRRepeat the conformity check from the start.

Fault finding - Dealing with command modes
COMMANDS AND CLEARING:
Before using these clearing commands, engine and vehicle speeds must be zero and the selector lever must be in
position P or N.
AC024 Sequential actuator control
This command activates sequence solenoids EVS1 to EVS6 simultaneously to check that they operate correctly.
RZ004 Fault memory
This command clears present and stored faults from the automatic transmission computer.
RZ005 Self-adapting programs
This command is used to clear the automatic transmission computer auto-adaptives following reprogramming, or
after transmission components have been replaced.
After running this command, carry out a road test with the vehicle before returning it to the customer. This is because
the automatic transmission may malfunction during the time taken for the self-adapting programs to re-install.
AFTER REPAIRRepeat the conformity check from the start.

If any of the 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.
Control of solenoid valve EVS1:
●connection code 5AV, between components 119 and 754.
Control of solenoid valve EVS2:
●connection code 5AW, between components 119 and 754.
Control of solenoid valve EVS3:
●connection code 5AX, between components 119 and 754.
Control of solenoid valve EVS4:
●connection code 5AY, between components 119 and 754.
Control of solenoid valve EVS5:
●connection code 5DL, between components 119 and 754.
Control of solenoid valve EVS6:
●connection code 5DM, between components 119 and 754.
If any of the 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.
Test the solenoid valves then check for faults on the computer.
AFTER REPAIRRepeat the conformity check from the start.

ALP1 No dialogue with the computer
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.

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 at P or N.
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, Multifunction switch, Removal - Refitting (for Mégane II) and MR 370 Mechanical, 23A,
Automatic transmission, Multifunction switch, Adjustment (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 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)).
Is the value higher than 0.2 bar?
