STORED
MULTIFUNCTION SWITCH IN PROHIBITED POSITION
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.
