NOTESConditions for applying the fault finding procedure to stored faults:
The fault appears when the selector lever is moved from position P to position D with
a stop at each lever position.
Special notes:
Use bornier Elé. 1681 for all operations on the computer connectors.
Use the Mégane II or Scénic II wiring diagram Technical Note.
ACheck the consistency between: ET012 Gear lever position, the instrument panel display and the gear lever
position while shifting the lever into all the possible positions.
BTo check that there is no clearance between the gearbox output lever and the multifunction switch shaft, see
test 1 Checking the gearbox output lever clearance
–If there is clearance, check the tightness of the retaining nut. If this has no effect, replace the lever.
–If there is no clearance, move on to the next step.
CAdjust the control (see MR 370 Mechanical, 23A Automatic transmission, Automatic transmission control
unit (for Mégane II and Scénic II)).
–If the adjustment is correct, then the procedure is complete.
–If the adjustment is incorrect, move on to the next step.
DCheck the cleanliness, condition and mounting of the multifunction switch.
Check the adjustment of the CMF* in neutral (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)).
–If the adjustment is incorrect, adjust the multifunction switch.
–If the adjustment is correct, move on to the next step.
ECheck the adjustment of the ball detent blade on the gearbox output lever at the unclipped external control
(see Technical Note 4194A: Automatic transmission indicator strip flashing):
–If the adjustment is incorrect, adjust the ball detent blade.
–If the check is correct, move on to the electrical check.
Repair if necessary.
Check the condition and cleanliness of the connector A connections.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

DEF: Signal outside upper limit
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present following a delay of 5 seconds, with the engine running,
the vehicle stationary with a gear engaged and a difference of more than 384 rpm
between the engine speed and the turbine speed.
Special notes:
Use bornier Elé. 1681 for all operations on the computer connectors.
Use the Mégane II or Scénic II wiring diagram Technical Note.
Check the oil level in the engine and gearbox.
Top up 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)).
Check the engine speed:
–Possible engine speed instability
–Deal with the faults displayed on the diagnostic tool for the injection computer.
Deal with the other faults first.
Check the turbine speed:
–Possible inconsistency with the turbine speed,
–Possible turbine sensor fault,
–Possible solenoid valve oil pressure fault.
Check the oil pressure with the engine switched off using PR003 Oil pressure: if the pressure is greater than
0.2 bars, replace the pressure sensor.
–Warm engine with gearbox oil temperature between 65 and 90˚C.
–Measure the line pressure under the 3 following conditions:
IMPORTANT
The vehicle must be stationary: handbrake on and brake pedal depressed, no accessories operating
(e.g.: air conditioning)
1Engine speed idling:
Shift the gear lever to R, N and D, the pressure reading must be greater than 2.5 bar.
2Engine speed at 1200 rpm:
–gear lever in R position, the pressure reading must be greater than 4 bar.
–gear lever in D position, the pressure reading in first gear must be greater than 5.5 bar.
3Engine speed at 2200 rpm:
–gear lever in R position, the pressure reading must be greater than 11 bar.
–gear lever in D position, the pressure reading in first gear must be greater than 11 bar.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
