NOTESIf the following faults are present or stored, deal with them first:
–DF003 Analogue sensor supply.
–DF005 Oil pressure sensor circuit.
–DF016 Lock-up solenoid valve circuit.
–DF017 Exchanger flow solenoid valve circuit.
–DF023 Gearbox oil temperature sensor circuit.
–DF036 Pressure modulating solenoid valve circuit.
–DF131 Slipping.
–DF226 Automatic transmission internal pressure.
–DF237 Invalid coolant temperature signal.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after a road test.
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, Oil change (for Scenic II)).
Check that the water-oil exchanger is not blocked.
Measure the resistance of component 754 between the following connections:
●connection code 5BC,
●connection code 5BB.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring. Otherwise replace the wiring.
The resistance should be between:
2660 Ω < R < 2360 Ω at 20˚C and 327 Ω < R < 290 Ω at 80˚C.
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.

NOTESNone.
Run a multiplex network test (see 88B, Multiplex).
If the fault is still present, carry out fault finding on injection system (see 17B, Petrol injection or 13B, Diesel
injection).
If the problem 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.

NOTESSpecial notes:
Only apply the checks if the parameter is inconsistent.
Run a multiplex network test (see 88B, Multiplex).
If parameter PR001 Coolant temperature is absent, refer to the interpretation of the parameter (see MR 366
Megane, 17B, Petrol injection or 13B, Diesel injection).
AFTER REPAIRRepeat the conformity check from the start.
