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 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 component detected as faulty,
–the condition of the wires (melted or split insulation, wear).
Conformity check
The aim of the conformity check is to check the data that does not display 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 the permitted tolerance values, 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 processed by
customer complaints. 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 forced + after ignition feed has been cut off by checking that the computer warning lights on the
instrument panel have gone out.
A synopsis of the general procedure to follow is provided on the following page in the form of a flow chart.

The mobile connectivity computer enables music files to be played (MP3, WMA, etc.) on:
•USB mobile peripherals (USB key, MP3 player, etc.) (Except hard disk with own power supply),
•audio peripherals via the jack socket.
The multimedia 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 according to the vehicle
type.
•Modify various acoustic parameters (base, treble, front/rear balance, etc.).
•Use the hands-free telephone function (sound relayed towards the radio speakers) with a Bluetooth telephone.
•Use voice recognition for the telephone functions (button on the radio control satellite). The voice identifier can be
recorded.
•Benefit from a connection for a CD changer.
•Possibility of connecting a peripheral with a USB port, Jack socket, etc.
•Has anti-theft protection
Computer activation system
The mobile connectivity computer has an activation system.
The mobile connectivity computer is activated under the following conditions:
•by pressing the radio ON/OFF button,
•by starting the engine.
The mobile connectivity computer is switched off under the following conditions:
•The ignition is switched off.
•Door opened (Clio III)
•Door opened for 1 minute (New Twingo)
•By pressing the radio ON/OFF button (Clio III and New Twingo).
The multimedia connection unit (Display or Multimedia connection unit ) is activated by the UCH (central door
unlocking); this then activates the multimedia computers (Navigation, Radio, mobile connectivity computer, etc.) via
the "Activation signal" connections.

VP003: Write V.I.N
This command permits manual entry of the vehicle's VIN into the computer. Use this command each time
the computer is replaced. The VIN number is inscribed on the manufacturer's plate.
Procedure for writing the VIN
•Establish dialogue with the navigation computer.
•Select the Repair mode menu.
•Select the Other configuration menu.
•Select line VP003 Write VIN.
•Enter the VIN.
•Exit fault finding mode.
•Switch off the ignition.
•Wait for the end of the Powerlatch* phase (20 minutes maximum).
•Reread the VIN in the Identification menu to confirm ID008 VIN code.
VP001: Enter last After-Sales operation date
This command is used to enter the date of the last After-Sales operation on the radio.
Consecutively enter the six figures of the date: two for the year, two for the month and two for the day.
E.g. 000706 (06 July 2000).
Reread the date of the last After-sales operation in the Identification menu to confirm ID012 Last After-Sales
operation date.
*Powerlatch: Time required for injection computer supply after + 12 V after ignition feed cut-off.

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.

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 present: + After ignition feed 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.
If the vehicle is equipped with a navigation computer, the mobile connectivity computer
is connected to the navigation computer, component code 662, otherwise it is
connected to the radio, component code 261.
