NOTESThere must be no present or stored faults.
Note: ET009 Repeat button is not present on the New Twingo.
For a vehicle equipped with a Navigation computer, use component 1714, Multimedia
connection unit, for fault finding on the Multimedia interface unit.
Otherwise use component 653, display computer.
Use the Wiring Diagrams Technical Note for Clio III or New Twingo.
Check the condition and connection:
●of the radio control satellite connector, component code 1519 (for Clio III) or component code 325 (for New
Twingo).
●of the display connector, component code 653, or the multimedia connection unit connector, component code
1714, depending on the vehicle equipment.
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.
