NOTESFor 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.
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 New Twingo: F48 (15 A),
–for Clio III: F14 (5 A), F2 (20 A) and unit fuse 710 (15 A).
Check the connection of the display connector, component code 653, or the multimedia connection unit connector,
component code 1714, and the condition of its connections.
If the connector(s) is 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 that the computer is correctly supplied by checking the following connections:
–BCP4 between components 260 and 653 or 1714,
–BPT between components 645 and 653 or 1714,
–BPT3 between components 260 and 653 or 1714,
–NAM between component 653 or 1714 and earth.
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.
