Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring 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, insulators and wiring harness routing.
Look for signs of oxidation.
Physical inspection
While manipulating the wiring, use the diagnostic tool to note any change in fault status from stored to present.
Make sure 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 sockets.
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 with another wire.
If a fault is detected, repair or replace the wiring harness.

Use the Wiring Diagrams Technical Note for LOGAN, SANDERO, DUSTER,
MEGANE II ph1 and ph2, SCENIC II, MASTER II ph2 and ph3, THALIA 2/SYMBOL
2, CLIO II F6, KANGOO VLL.
Ensure that the diagnostic tool is not the cause of the fault by using it to establish dialogue with a
computer on another vehicle. If the diagnostic tool is not causing the fault and dialogue cannot be established
with any other computer on the same vehicle, it may be that a faulty computer is disrupting the fault finding line.
Use a process of successive disconnections to locate this computer.
Check the battery voltage, component code 107, and perform the necessary operations to obtain the correct
voltage (12 V < X < 15 V).
Check the condition of the fuses in the passenger compartment fuse and relay box, component code 260 for
MEGANE II ph1 and ph2, SCENIC II, KANGOO VLL or component code 1016 for LOGAN, SANDERO, DUSTER,
MASTER II ph2 and ph3, THALIA 2/SYMBOL 2, CLIO II F6.
Check the connection of the anti-theft tracking unit connector, component code 2186.
If the connector is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.

Check that the anti-theft tracking unit, component code 2186, is correctly supplied on the following connections:
For LOGAN, SANDERO, DUSTER, THALIA 2/SYMBOL 2, CLIO II F6:
–BP56 on component 2186 (+ before ignition feed),
–AP10 on component 2186 (+ after ignition feed).
For MEGANE II and SCENIC II:
–BP32 on component 2186 (+ before ignition feed),
–AP43 on component 2186 (+ after ignition feed).
For MASTER II:
–BP on component 2186 (+ before ignition feed),
–AP on component 2186 (+ after ignition feed).
For KANGOO VLL:
–BP3 and BP10 between components 2186 and 260 (+ before ignition feed),
–AP10 between components 2186 and 260 (+ after ignition feed),
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
If the fuses are faulty in the passenger compartment fuse and relay box, component code 260 for MEGANE II,
SCENIC II and KANGOO VLL or component code 1016 for LOGAN, SANDERO, DUSTER, MASTER II, THALIA
2/SYMBOL 2, CLIO II F6, replace them.
