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 Clio III or New Twingo.

Check the connection and condition of the connectors of the display computer, component code 653 or of the
multimedia connection unit computer, 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.
Disconnect the computer connector and check the conformity of 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 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.
