Faults
Faults are declared either present or stored (depending on whether they appeared in a certain context and
disappeared since, or whether they remain present but have not been diagnosed within the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is switched on
after the + after ignition feed (without any system components being active).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the instructions in the Notes section.
If the fault is confirmed when the instructions in the Notes section are applied, the fault is present. Deal with the
fault.
If the fault is not confirmed, check:
–the electrical lines which correspond to the fault,
–the connectors for these lines (for oxidation, bent pins, etc.),
–the resistance of the component detected as faulty,
–the condition of the wires (melted or split insulation, wear).
Conformity check
The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool because the
data is inconsistent. Therefore, this stage is used to:
–carry out fault finding on faults that do not have a fault display, and which may correspond to a customer
complaint,
–check that the system is operating correctly and that there is no risk of a fault recurring after repairs.
This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.
If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult the
corresponding fault finding page.
Customer complaints - Fault finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be processed by
customer complaint.
A synopsis of the general procedure to follow is provided on the following page in
the form of a flow chart.

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.
