3. REMINDERS
Procedure
To run fault finding on the vehicle's computers, switch on the ignition in fault finding mode (forced + after ignition
feed).
Proceed as follows:

4. FAULT FINDING PROCEDURE (continued)
Wiring check:
Fault finding problems:
Disconnecting the connectors and/or manipulating the wiring may temporarily remove the cause of a fault.
Electrical measurements of the voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection:
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulation and wiring routing.
Look for signs of oxidation.
Tactile inspection:
While manipulating the wiring, use the diagnostic tool to note any change in fault status from stored to present.
Check that the connectors are correctly tightened, apply light pressure to the connectors, twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component:
Disconnect the connectors and check the appearance of the clips and tabs, as well as their crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Make sure no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check:
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or with another wire.
If a fault is detected, repair or replace the wiring harness.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present during a road test with a warm engine at an engine speed
above 1500 rpm.
Special note:
The wiring harness connecting the injection computer to the pinking sensor is
"shielded", from this a short circuit to + 12 V is improbable.
Check the cleanliness and condition of the pinking sensor and its connections.
Check the tightness of the pinking sensor.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Use the "Universal bornier" to check the insulation and continuity of the following connections:

Computer, connectorB, track B4 track 1of the pinking sensor
Computer, connectorB, track B2Pinking sensor screening
Repair if necessary.

STOREDCLUTCH PEDAL CIRCUIT
1.DEF: Component in bad condition
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is present with the engine running and following a check on the number of
times the clutch pedal is depressed in relation to the number of gear changes
calculated by the computer.
Special note:
– engine speed surges when changing gear,
– the acquisition is made if the vehicle is not fitted with an automatic transmission,
– in the event of a fault, before replacing any component, check using the diagnostic
tool that the clutch contact is operational and that the recommended clutch pedal
clearance is still valid.
– In the event of an open circuit or short circuit to + 12 V, the clutch pedal is
depressed all the time which makes it impossible to select a cruising speed in cruise
control mode. The speed limiter remains operational in defect mode (inaccurate
speed restriction),
–If short circuit to earth, status ET405 Clutch pedal switch remains INACTIVE.
Check the cleanliness, condition and fitting of the clutch pedal switch.
Repair if necessary.
If the fault is still present, disconnect the switch. Check that when the clutch pedal is depressed, the switch is
closed, and when the clutch pedal is released, the switch is open.
Replace the switch if necessary.
If the fault is still present, manipulate the harness to see if the status changes.
Look for any damage to the wiring harness, and check the condition and connection of the connectors of the
injection computer and clutch pedal switch.
Repair if necessary.
If the fault is still present, check the earth on track 2 of the switch.
If the earth is not present on track 2, check for insulation, continuity and the absence of interference
resistance on the following connection:
earth track 1 Clutch pedal switch
Repair if necessary.
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present with the engine running and with a heating and air
conditioning system request.
Priorities when dealing with a combination of faults:
Deal with fault DF232 Refrigerant pressure sensor circuit first if it is present or
stored
When the fault is present or stored, the heating and air conditioning system is inhibited.
Check fuse F22 (10A) of the UPC and the condition of the air conditioning compressor connector.
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the air conditioning compressor wiring.
If the wiring is faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Manually check whether the compressor is jammed (turn the clutch plate manually to check that there is no point
of resistance). In the event of sticking, replace the air conditioning compressor (see MR 364 (Mégane II) or 370
(Scénic II), Mechanical, Heating and air conditioning system, 62A, Air conditioning, Compressor:
Removal - Refitting).
Top up with freon, check for any leaks and repair if necessary (see MR 364 (Mégane II) or 370 (Scénic II),
Mechanical, Heating and air conditioning system, 62A, Air conditioning, Refrigerant circuit: checks,
Refrigerant circuit: Draining - Filling).
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by another
check with the diagnostic tool.
