NOTESUse the Wiring Diagrams Technical Note for Espace IV Phase 2 or Scénic II
Phase 2.
Important: After switching on the system, there can be a delay of 20 seconds before
dialogue is established.
Try to establish dialogue with a computer on another vehicle to check that the diagnostic tool is not faulty. 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 presence and condition of the computer supply fuses:
–for Espace IV Phase 2: F15 (30 A),
–for Scénic II Phase 2: SHUNT (2AA).
Check the connection of the multimedia network interface unit connector, component code 1714 and the condition
of its connections.
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check that the computer is correctly supplied by checking 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(s) is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.

Check that the diagnostic socket, component code 225, is correctly supplied on the following connections:
–for Espace IV Phase 2:
•BCP4 between components 225 and unitary fuse 710,
•AP10 between components 225 and 260 (+ after ignition feed),
NC and MB of component 225.
–for Scénic II Phase 2:
•BP32 between components 225 and 260,
•AP43 between components 225 and 1337 (+ after ignition feed),
•NAM and MAM of component 225.
Check the continuity, insulation and absence of interference resistance on the following connections:
•107W and 107X between components 1714 and 225,
•133B and 133C between components 1714 and 225 (for Espace IV Phase 2)
•133B and 133C between components 1714 and 645 (for Scénic II Phase 2).
If the connection(s) is 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 dialogue is still not established after these various checks, replace the multimedia network interface unit,
component code 1714 (see MR 405 (Espace IV Phase 2) or MR 370 (Scénic II Phase 2) Mechanical, 83C,
On-board telematics system, Multimedia network interface unit: Removal - Refitting).
If the fault is still present, contact Techline.
