To cut off + after ignition, proceed as follows:
–Disconnect the diagnostic tool.
–Press the Start button twice briefly (less than 3 seconds).
–Ensure that the + after ignition feed has been cut off by checking that the computer indicator lights on the
instrument panel have gone out.
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. Note:
The left and right-hand xenon bulb computers are supplied when the dipped headlights are lit.
Therefore fault finding can only be carried out on them after the ignition has been switched on in fault finding mode
(forced + after ignition feed) and the dipped headlights have been switched on.
A synopsis of the general procedure to follow is provided on the following page in the form of a flow chart.

Reading automatic transmission configuration
The read-configuration commands (LCXXX) are used to display the current computer configuration in relation to the
equipment installed in the vehicle.
Writing automatic transmission configuration
The write-configuration commands (CFXXX) are used to configure the computer for the equipment installed in the
vehicle.
These three settings are important because they optimise transmission operation for the vehicle. If they are not
entered properly, automatic transmission operation may be impaired.Configuration reading Configuration

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.
Use Technical Note Wiring diagram, Mégane II
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 370 Mechanical, 23A Automatic transmission, Automatic transmission control
unit (for Mégane II and Scénic II)).
–If the setting is correct, the procedure is complete.

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 adjustment is incorrect, adjust the ball detent blade.
–If the check is correct, go on to the electrical check.
Repair if necessary.
Check the condition and cleanliness of the connector A connections.
If the continuity is faulty, change the multifunction switch.
