NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the brake pedal is depressed, or during a road test.
Special notes:
If the fault is present, the cruise control/speed limiter is deactivated.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This check enables the condition and the conformity of the engine wiring harness to be checked.
1. DEF
NOTESNone
Check the brake pedal switch connections.
Check the condition and adjustment of the brake pedal switch.
Repair if necessary.
Check the conformity of the brake light switch:
For Mégane II and Scénic II without ESP:
Brake pedal released:
– continuity between connections 5A and BPT,
– infinite resistance between connections 65A and SP17.
Brake pedal depressed:
– infinite resistance between connections 5A and BPT,
– continuity between the connections 65A and SP17.
For Mégane II and Scénic II with ESP:
Brake pedal released:
– continuity between connections 5A and BPT,
– infinite resistance between connections 65G and SP17.
Brake pedal depressed:
– infinite resistance between connections 5A and BPT,
– continuity between the connections 65G and SP17.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

NOTESPriority when dealing with a number of faults:
Deal with fault DF004 Turbocharging pressure sensor
circuit first if it is present or stored.
Check the turbocharging pressure sensor connections,
Check the connections of the turbocharging solenoid valve,
Check the injection computer connections.
Repair if necessary.
Check the conformity of the turbocharging pressure signal (refer to the interpretation of parameter PR041
Turbocharging pressure).
Make sure the turbocharging pressure relief solenoid valve is not jammed open:
– With the engine switched off, disconnect the inlet and outlet hoses from the solenoid valve.
– connect a vacuum pump to the inlet union and apply a vacuum pressure.
– If the vacuum pressure is not maintained, replace the solenoid valve.
Check that the turbocharger control rod has not seized:
– With the engine stopped, check that the turbocharger control rod is in the rest position (the control rod
engaged),
– apply a vacuum of 700 mbar < X < 900 mbar to the hose connected to the turbocharger control diaphragm,
– if the diaphragm retains the vacuum, check the movement and setting of the turbocharger control rod (see MR
364 (Mégane II), MR 370 (Scénic II), MR 395 (Laguna II), Mechanical, 12B, Turbocharging).
If the control rod is seized, replace the turbocharger.
If the fault is still present, run test 2 Air line at the turbocharger, test 6 Turbocharger control solenoid valve
check and test 7 Turbocharger.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

1 NO particle filter regeneration.
2 On the repair order, note the parameter and the status that correspond to the last failure:
– Mileage of the last DF312.
– Mileage of the last failures.
– Engine statuses of the last failures.
E.g.: PR787 = 2794 miles (4657 km); PR801 = 2760 miles (4600 km); engine status = STOPPED.
3 Interpretation of the values written on the order of repair by the service advisor for the customer:
Before the last time the warning light or Particle Filter message came on (appeared at the Mileage of the last
DF312), the customer had not respected the driving recommendations: the failure that occurred at the Mileage of
the last failure is due to the engine being switched off.
4 Check the weight of soot: PR383 Weight of soot in the particle filter.
If PR383
≥ 1 g. Apply the procedure for test 8 Manual clearing of the soot weight.
5 Explain to the customer the procedure to turn off the warning light, backed up by the parameters written in the
repair order: see PART D.
PA R T C
1- Carry out a regeneration in the Renault network with the approval of the Techline.
2- Change the oil and replace the oil filter if requested by a message on the diagnostic tool.
3- Run command SC036 Reinitialise programming and select After particle filter replacement.
4- Explain to the customer the procedure for regeneration when driving in order to avoid unnecessary repairs: see
PART D.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

STATUS DEFINITIONYES, this status indicates that the air conditioning is active.
NO, this status indicates that the air conditioning is inactive.
NOTESSpecial notes
Only perform these tests if the statuses do not correspond with the system
programming functions.
Engine running, engine coolant temperature > 80 °C
YES
The air conditioning authorisation only changes to YES if:
– the air conditioning request has been made by the driver (air conditioning switch in
AC or AUTO position with minimum ventilation),
– the engine is not under full load,
– the air conditioning system is not faulty.
Conformity check with engine stopped and ignition on
NOStatus ET004 remains NO under the following conditions:
– Vehicle stopped with the ignition on,
– faults present in the air conditioning circuit,
– no air conditioning request made by the driver,
– engine under full load.
If status ET004 remains NO then the air conditioning should be authorised, check:
– that the air conditioning compressor is activated correctly,
– the air conditioning system feed fuses,
– the presence of refrigerant in the air conditioning circuit,
– that the refrigerant fluid pressure value is consistent at idle speed.
If the fault is still present, check the air conditioning computer faults (see62C, Air
conditioning).
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
