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 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.

AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults using command RZ001 Fault memory.
Deal with any other faults.

2.DEF: Undervoltage.
NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the multimedia system has been switched on.
Special notes:
The undervoltage fault appears if the computer feed voltage is less than or equal to
7.5 V for at least 1 second.
The overvoltage fault appears if the computer feed voltage is greater than or equal to
18.5 V for at least 1 second.
Use the Wiring Diagrams Technical Note for Espace IV Phase 2 or Scénic II
Phase 2.

NOTESNone.
Check the battery and perform an alternator supply test (see 16A, Starting, Charging).

2.DEFNOTESNone.
Remove the card from the reader or the key from the ignition, then check the condition of the battery, component
code 107.
Check the battery: leaks, incorrectly fitted, loosened battery terminal, and corrosion.
Check the earth connections of the vehicle: battery/chassis, engine/chassis, starter/engine, alternator/engine,
gearbox/chassis.
If the fault is detected, resolve the abnormal contact fault.
Check the battery and perform an alternator supply test (see 16A, Starting, Charging).
Check the condition of fuse F15 (30 A) for Espace IV Phase 2 or fuse SHUNT (2AA) for Scénic II Phase 2.
Check the connection and condition of the connectors of the multimedia network interface unit computer,
component code 1714, depending on the vehicle equipment.
If any connectors are faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connectors, otherwise replace the wiring.
Disconnect the computer connector and check the conformity of the following connections:
•BP3A between components 260 and 1714 (for Espace IV Phase 2),
•BCP3 between components 260 and 1714 (for Scénic II Phase 2),
•BPT between components 645 and 1714 (for Scénic II Phase 2),
•MAN between component 1714 and earth (for Scénic II Phase 2),
•NC between component 1714 and earth (for Espace IV Phase 2).
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.

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.
