Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring harness may temporarily remove the cause of a fault.
Electrical measurements of 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 harness routing.
Look for signs of oxidation.
Tactile inspection
While manipulating the wiring harness, use the diagnostic tool to note any change in fault status from stored to
present.
Check that the connectors are properly locked.
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 the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the holes.
Check that 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 to another wire.
If a fault is detected, repair or replace the wiring harness.

If faults DF024 No instrument panel multiplex signal and DF026 No fold-out unit
multiplex signal are present, run command VP005 Computer configuration to
reconfigure the system (see Configuration and programming).
Conditions for applying fault finding procedures to stored faults:
Apply this fault finding procedure if the fault reappears as present or stored after it has
been cleared and the ignition has been switched off and on again.
Special note:
Apply this fault procedure only for vehicles equipped with an instrument panel dot
matrix display (Top of the range Mégane II phase 2).
Use the Wiring Diagrams Technical Note for the Mégane II.
Look for any damage to the wiring harness, check the condition and connection of the connectors on
components 261 and 247.
Manipulate the wiring harness in order to produce a change in the fault status (present → stored).
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Using the universal bornier, check the insulation, continuity and the absence of interference resistance on
the following connections:
●connection code 107W,
●connection code 107X,
between components 261 and 247.
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 it.
If the fault is still present, run fault finding on the instrument panel (see 83A, Instrument panel) and the multiplex
network (see 88B, Multiplexing).
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the faults from the 4R radio navigation computer memory using command RZ001
