NOTESConditions for applying the fault finding procedure to stored faults:
The fault is reported present when the gear lever is shifted from Park to Drive
(with a stop at each lever position).
Special notes:
Use bornier Elé. 1681 for all operations on the computer connectors.
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 is ineffective, replace the lever.
–If there is no play, go on to the next step.
CAdjust the control (see MR 364 Mechanical, 23A Automatic transmission, Automatic transmission control
unit (for Mégane II) and MR 370 Mechanical, 23A Automatic transmission, Automatic transmission
control unit (for Scénic II)).
–If the setting is correct, the procedure is complete.
–If the setting is not correct, go 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 setting is correct, go 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 check is not correct, adjust the locating ball spring.
–If the check is correct, go on to the electrical check.
Repair if necessary.
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.
