Run a multiplex network test (see 88B, Multiplexing).
If the fault is still present, run fault finding on the Anti-lock braking and Electronic stability program systems
(see 38C, Anti-lock braking system).
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.

NOTESRun fault finding on the injection system and make sure that it is working perfectly.
If the following faults are present or stored, deal with them first:
DF003 - DF005 - DF016 - DF017 - DF018 - DF020 - DF023 - DF024 - DF036 -
DF049 - DF131
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after a road test.
To make sure that there are no faults with the gearbox oil temperature sensor, apply the interpretation of fault
DF023 Gearbox oil temperature sensor.
To make sure that there are no faults with the exchanger flow solenoid valve, apply the interpretation of fault DF017
Exchanger flow solenoid valve circuit.
Check gearbox oil grade and level.
If an operation is 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 that the gearbox is not leaking oil.
Check that the water-oil exchanger is not blocked.
If the fault is still present, there is a definitely a mechanical or hydraulic fault.
Deal with the other faults then proceed with the conformity check.
If the fault is still present, contact the Techline.
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.
