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.

Thermal protection
Thermal protection is integrated in order to protect the radio.
The functions are restored when the internal temperature falls below 80˚C.
Car radio code
The radio is protected by a two-part anti-theft system:
•A 4-digit code,
•Information exchanged between the instrument panel and the radio.
This code is requested in the following cases:
•New vehicle,
•New radio,
•When a radio is swapped between vehicles.
Entering the code using the radio control satellite:
Press the lower button on the radio control satellite to confirm an entry.
Entering using the radio:
Enter the digits using buttons 1, 2, 3 and 4, and then confirm with button 6.
If the code is entered incorrectly, the radio will be locked (1 minute for the first error, 2 minutes for the second error,
4 minutes for the third error, etc., for a maximum of 32 minutes after each attempt).
After several attempts, if the fault is still present, contact the Techline.
Reminder:
The radio will operate for approximately 2 minutes in scrambled mode without the code having been entered
(with regular warning beeps).
Note:
If the battery is disconnected, it is not necessary to re-enter the radio anti-theft code.

NOTESThis fault is detected when the radio computer receives a radio programming key
(supplied from the VIN) that is invalid for the instrument panel via the multiplex network.
Use the diagnostic tool to check that the V.I.N. of the radio is identical to that of the instrument panel.
Configure the multimedia connection unit (see 86D, Multimedia connection unit, Configuration).
Enter the radio code (see Anti-theft code).
If the fault persists, contact your Techline.

NOTESUse the Wiring Diagrams Technical Note for Clio III or New Twingo.
NOTE: Switch on the side lights and position the lighting rheostat wheel in the centre
position.
The display, component code 653, is only available when the vehicle does not have the
navigation function.
The multimedia connection unit, component code 1714, is only available when the
vehicle has the navigation function.
Check the backlighting of the following components:
radio, display and instrument panel.
Are all of the components backlit?
Attempt to backlight these components
once again, and if no conclusion can be
made, contact the Techline.
