NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after:
–The + after ignition feed is activated,
–The multimedia system is switched on using the on/off button.
–The battery voltage is out of range (12 V < X < 15 V).
Use the Wiring Diagrams Technical Note for Clio III or New Twingo.
Remove the card from the reader or the key from the ignition, then check the condition of the battery.
Check the battery: leaks, incorrectly fitted, loosened battery terminal, and corrosion.
Check the earth connections of the vehicle: battery/chassis, engine/chassis, starter/engine, alternator/engine,
gearbox/chassis.
If the fault is detected, resolve the abnormal contact fault.
Check the battery and perform an alternator supply test (see 16A, Starting, Charging).
Check the conformity of the fuse of the fuse and relay box (use the Wiring Diagrams Technical Note for Clio III
or New Twingo):
–for New Twingo: F48 (15A),
–for Clio III: unit fuse 710 (15A) and F2 (20A) on component 260.
Replace the fuse if not correct.
Disconnect the connector of the mobile connectivity computer, component code 1959.
Check the continuity of the earth on connection NAM.
If the 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.

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the multimedia system was switched on using the
radio on/off button.
Use the Wiring Diagrams Technical Note for Clio III or New Twingo.
Check the connection and condition of the connectors of the mobile connectivity computer, component code
1959 and of the mobile connectivity terminal, component code 1877.
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 insulation, continuity and the absence of interference
resistance on the following connections:
–34PE between components 1959 and 1877,
–34PH between components 1959 and 1877,
–34PG between components 1959 and 1877,
–34PJ between components 1959 and 1877,
–34TE between components 1959 and 1877,
–34TJ between components 1959 and 1877,
–34TH between components 1959 and 1877,
–34TG between components 1959 and 1877.
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.
