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 to another wire.
If a fault is detected, repair or replace the wiring harness.

CO: Open circuit.
CC.0: Short circuit to earth.
CC.1: Short circuit to +12 volts.
NOTESFault finding procedure application conditions:
The fault is declared present after:
–The + after ignition feed is activated, then the multimedia system was switched on
using the on/off button.
–The fault is declared stored after the vehicle is completely shut off (1 minute after
locking).
If the fault is present, the multimedia functions do not operate.
Use the Wiring Diagrams Technical Note for Espace IV Phase 2 or Scénic II
Phase 2.
Check the connection and condition of the connectors of the radio, component code 261, the display, component
code 1127, and the multimedia network interface unit, component code 1714.
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the insulation to earth and to +12 V, the continuity, and the absence of interference resistance of the
following connections:
•34HU between components 261 and 1714,
•34HU between components 1127 and 1714.
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 persists, contact your Techline.
