STATUS DEFINITIONDownwards: This means that the wheel is turned downwards.
Upwards: This means that the wheel is turned upwards.
Inactive: This means that there is no action on the wheel.
NOTESThere must be no present or stored faults.
Use the Wiring Diagrams Technical Note for Espace IV Phase 2 or Scénic II
Phase 2.
Check the condition and connection of the radio control satellite connector, component code 1519 (for Scénic II
Phase 2) or component code 325 (for Espace IV Phase 2) and the multimedia network interface unit connector,
component code 1714.
If the 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.
Using the universal bornier, check the insulation, continuity and the absence of interference resistance on the
following connections:
•34AT between components 1519 (or 325) and 1714,
•34AR between components 1519 (or 325) and 1714,
•34AS between components 1519 (or 325) and 1714,
•34AQ between components 1519 (or 325) and 1714,
•34AU between components 1519 (or 325) and 1714,
•34AP between components 1519 (or 325) 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.
