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).
Note:
Apply this fault finding method if the fault reappears as present after having been
cleared
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 in the fuse and relay box:
•for New Twingo: F48 (15A),
•for Clio III: F2 (20A) and Unit fuse 710 (15A).
Replace the fuse if not correct.
Disconnect the connector of the radio 261.
Check the continuity of the earth on connection MAO (New Twingo) or MT (Clio III).
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.
Check the +12 V supply on connection BCP4 of component 261.
If the supply is not correct, check the insulation, continuity and absence of interference resistance on
connection code BCP4 between components 260 and 261.
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.
If the fault persists, contact your Techline.

NOTESUse the Wiring Diagrams Technical Note for Clio III or New Twingo.
Check for a CD changer in the vehicle.
Check the consistency between the configuration of the radio and the vehicle equipment by reading configuration
LC005 External components and correct if necessary, using SC002 Computer configuration.
Look for any signs of damage to the wiring harness, check the condition and connection of the connectors and
connections of components 261 and the CD changer.
If the connectors or connections are faulty and if there is a repair procedure (see Technical Note 6015A,
Electrical wiring repair, Wiring: Precautions for repair), repair the connector or the wiring, otherwise replace
the wiring.
If the vehicle is equipped with a CD changer, it was fitted as an accessory. Please refer to the handbook delivered
with the product.
If the checks are correct, replace the CD changer.
If the fault persists, contact your Techline.

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after:
–the + after ignition feed is activated,
–the multimedia system has been switched on using the on/off button.
Use the Wiring Diagrams Technical Note for Clio III or New Twingo.
For a vehicle equipped with a navigation system, use the multimedia connection unit
computer, component code 1714, for fault finding.
For a vehicle without a navigation system, use the display computer, component code
653, for fault finding.
Check the condition of the connector on the radio, component code 261, and, depending on the equipment level,
on the display, component code 653, or on the multimedia connection unit, component code 1714.
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 the insulation, continuity and absence of interference resistance on the following connections:
•34HY between,components 261 and 653 or 1714,
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the connection is correct, replace the radio (see MR 392 (Clio III) or MR 411 (New Twingo) Mechanical, 86A,
Radio, Radio: Removal - Refitting).
If the fault persists, contact your Techline.

ALP 1 No dialogue with the computer
NOTESTry 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).
Ensure that the communication conditions are met: + After ignition feed activated and
radio On/Off button pressed.
Use the Wiring Diagrams Technical Note for Clio III or 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.
Is the multimedia interface unit recognised
during the multiplex network test?The multimedia interface unit activates other
multimedia system computers.
Consult ALP 1 for the multimedia interface unit
(see 86D, Multimedia interface unit,
