Vdiag No.: A4
To cut off the + after ignition feed, proceed as follows:
Faults
Faults are declared either present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but have not been diagnosed within the current context).
The present or stored status of the faults should be taken into consideration when the diagnostic tool is used after
the + after ignition feed has been activated (without any of the system components being activated).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the Notes section.
If the fault is confirmed when the instructions are applied, the fault is present. Deal with the fault.
If the fault is not confirmed, check:
–the electrical lines which correspond to the fault,
–the connectors on these lines (corrosion, bent pins, etc.),
–the resistance of the faulty component,
–the condition of the wires (melted or cut insulation, wear). For vehicles with radio frequency remote control/key, use the key to switch off the ignition.
For vehicles with Renault cards,
Press the Start button twice briefly (less than 3 seconds),
Ensure that the + after ignition feed has been cut off by checking that the computer warning lights on the
instrument panel have gone out.

Conformity check
The purpose of the conformity check is to check data that does not produce a fault on the diagnostic tool when the
data is inconsistent. Therefore, this stage is used to:
–carry out fault finding on faults that do not have a fault display, and which may correspond to a customer complaint.
–check that the system is operating correctly and that there is no risk of a fault recurring after repair.
This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.
If a status is not behaving normally or a parameter is outside permitted tolerance values, you should consult the
corresponding fault finding page.
Customer complaints - Fault finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be dealt with by
customer complaints.
A synopsis of the general procedure to follow is provided on the following page in the form of a flow chart.

Role of main components
The radio computer manages the various multimedia system functions according to user requests and transmits
audio data to the vehicle via the speakers.
The radio uses an amplified aerial system to improve radio reception.
The aerial amplifier is incorporated into the roof aerial.
The speakers reproduce the radio system's sound inside the vehicle.
The microphone allows the telephone to be used in hands-free mode via a Bluetooth connection.
The tweeters reproduce the high-frequency sounds of the radio system.
The multimedia interface unit (Display or Multimedia connection unit) receives various signals from the vehicle CAN
(speed, status of exterior lights) and retransmits them for the radio via the Multimedia CAN.
The multimedia interface unit (Display or Multimedia connection unit) transmits the activation signal to the radio and
to the other computers that participate in the multimedia function when the user activates the radio button.
The display shows various multimedia information such as the radio information, the time, etc.
The radio control satellite allows various functions of the radio to be accessed.

The radio includes the following functions:
•Radio reception (AM, FM).
•CD/MP3 playing.
The system offers the following possibilities:
•Choose FM radio stations using the presets, the list or manual selection.
•Have access to an automatically updated FM radio list.
•Listen to CDs and MP3s.
•Control the radio using the radio control satellite.
•Have access to optimised audio and acoustic telephone configurations for each vehicle.
•Modify various acoustic parameters (base, treble, front/rear balance, etc.).
•Benefit from a connection for a CD changer.
•Possibility of connecting a peripheral with a USB port, Jack socket, etc.
•Anti-theft protection.
Computer activation system
The radio has an activation system.
The radio is switched on under the following conditions:
•by pressing the radio ON/OFF button,
•when the engine is started, the radio is switched on automatically.
The radio is switched off under the following conditions:
•The ignition is switched off.
•Door opened (Clio III)
•1 minute after a door is opened (New Twingo)
•By pressing the radio ON/OFF button (Clio III and New Twingo).
•In the last case, if the vehicle engine is running, the radio will be switched off from a user point of view, but will be
considered operational from an electrical point of view. If the ignition is switched off, the radio will be off.
The computer activation system is managed by the UCH, which activates the display with a timed + battery supply.
The activated display in turn activates all of the computers involved in the multimedia function

To remove and refit the radio, consult the Repair Manual for the vehicle concerned:
–Clio III (see MR 392, Mechanical, 86A, Radio, Radio: Removal - Refitting).
–New Twingo (see MR 411, Mechanical, 86A, Radio, Radio: Removal - Refitting).
Operations to perform before replacing the radio computer:
–With the approval of the Techline, read the fault code and perform the conformity check to determine whether the
fault is detected before replacing the computer.
–Remove any CDs before removing the computer or when replacing the CD changer.
–Switch off the ignition and remove the computer.
Operations to perform after replacing the radio computer:
–Connect the diagnostic tool, switch on the radio and establish dialogue with the computer.
–For New Twingo: before configuring the radio, it is essential to correctly configure the display (see 86D,
Multimedia connection unit).
–Configure the computer using special command SC002 Computer configuration (see Configuration).
–Enter the VIN code using command VP001 Write VIN (see Programming).
–Enter the computer replacement date using command VP003 Enter After-Sales operation date
(see Programming).
–Check that there are no faults and that the radio functions correctly, then enter the anti-theft code if the radio
requests it (see Anti-theft code).

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.
