Fault finding – Introduction
1. SCOPE OF THIS DOCUMENT
This document presents the fault finding method applicable to all computers with the following specifications:
2. PREREQUISITES FOR FAULT FINDING
Documentation type
Fault finding procedures (this document):
– Assisted fault finding (integrated into the diagnostic tool), Dialogys.
Wiring Diagrams:
– Visu-Schéma (CD-ROM), paper.
Type of diagnostic tools
–CLIP
Special tooling required
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:
– with the vehicle card in the card reader,
– press and hold Start button (longer than 5 seconds) with start-up conditions not fulfilled,
– connect the diagnostic tool and perform the required operations.
To cut off the + after ignition feed, proceed as follows:
– disconnect the diagnostic tool,
– press the Start button twice briefly (less than 3 seconds),
– Check that the + after ignition feed has been cut off by checking that the computer warning lights on the instrument
panel have gone out. Vehicle(s): Mégane II / Mégane Sport / Scénic II

Note:
The left-hand and right-hand xenon bulb computers are powered when the dipped headlights are lit.
Fault finding procedures can only be carried out on them after the ignition has been switched on in fault finding
mode (+ after ignition imposed) and the dipped headlights are on.

STOREDCAMSHAFT SENSOR SIGNAL
1.DEF : camshaft tooth event
2.DEF : dephasing measurement out of range
NOTESIf faults DF084 or DF046 are present or stored, deal with them first.
In the event of a combination of faults DF154 Flywheel signal sensor circuit,
DF080 Camshaft dephaser circuit and DF119, ignore fault DF080 and deal with
the other 2 faults first.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after a road test.
Check the cleanliness and the condition of the camshaft sensor connectors.
Check the condition and the cleanliness of the camshaft sensor.
With the ignition on, check for + 12 V on the camshaft sensor connector
(see the connector track number in the appropriate wiring diagram).
If +12V is not present:
– disconnect the battery,
– disconnect the connector marked PPM1 in the Protection and Switching Unit,
– check the cleanliness and condition of the connections,
– Use the Universal bornier to check the continuity of the following connection:
Protection and Switching Unit connector PPM1 track 2 Camshaft sensor
Reconnect the Switching Protection Unit connector and reconnect the battery.
With the ignition on, if there is still no +12V at the camshaft sensor connector, there is a fault in the Protection
and Switching Unit.
Contact the Techline.
Disconnect the battery.
Disconnect the computer. Check the cleanliness and condition of the connections.
Use the universal bornier to check the insulation and continuity of the following connections:
Computer track E2, connector C Camshaft sensor
Computer track F1, connector C Camshaft sensor
(see connector track numbers in the corresponding wiring diagram).
If the fault is still present, there is definitely a fault with the camshaft sensor target.
Refer to the relevant section in the Workshop Repair Manual.
AFTER REPAIRApply the Stored fault diagnostic application conditions:
– If the fault is present, continue to deal with the fault.
– If the fault is stored, ignore it.
Deal with any other faults.
Clear the stored faults.

IF THE PUMP DOES
NOT OPERATEDisconnect the fuel pump.
Check the cleanliness and condition of the connections.
Check for the + 12 V feed on the fuel pump connector with the ignition on (see
Technical Note 8227 Wiring Diagram, MEGANE II, 456).
If there is no + 12V:
– disconnect the battery,
– disconnect the connector marked PPH2 in the Protection and Switching Unit,
– check the cleanliness and condition of the connections,
– using the Universal bornier, check for continuity on the following connection:
Protection and Switching Unit
connector PPH2 track 5Fuel pump connector
Repair if necessary.
Reconnect the Protection and Switching Unit connector and reconnect the battery.
If the + 12 V feed is still not present on the fuel pump relay connector with the ignition
on, there is a fault with the Protection and Switching Unit.
Contact the Techline.
Check that the earth on the fuel pump connector is present with the ignition on
(seeTechnical Note 8227 Wiring Diagram, MEGANE II, 456).
Repair if necessary.
If the fault is still present, replace the fuel pump.
