To cut off the + after ignition feed, proceed as follows:
Faults
Faults are declared present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but are not diagnosed within the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is switched on
after the + after ignition feed (without any system components being active).
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 instructions in the Notes section.
If the fault is confirmed when the instructions in the Notes section 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 data that does not produce a fault on the diagnostic tool because 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 repairs.
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 key/radiofrequency remote control, use the key to switch off the ignition.
For vehicles with a Renault card,
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 indicator 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.

Fault finding - Functions
General operation
The NAV 4R system includes the following functions:
●CD multi-changer (according to options).
●Satellite guidance navigation.
●Display (according to options).
●External thermometer.
●Clock.
●Audio.
●Seat belt warning light (Laguna II only).
1 - CD multi-changer
The CD multi-changer located on the dashboard can hold up to 6 CDs. Audio CDs and CDs recorded by the
customer may be played.
The CD changer does not play MP3 CDs.
2 - Navigation
This function guides the driver by displaying maps and issuing voice messages. The addresses for guidance are
entered using the keypad.
3 - Display
The display is used to show information such as navigation maps, radio, CD title (MP3 CDs optional), time,
temperature, etc.
4 - Thermometer
The 4R central communication unit may display the exterior temperature via:
–the UCH (only on Mégane and Scénic II phase 2),
–the sensor located on the right-hand door mirror (other vehicles).
The temperature is also transmitted to the climate control computer. This parameter can be viewed using parameter
PR006 External temperature.
5 - Clock
This function allows the time to be displayed on the video screen.
6 - Audio
Two audio systems are available:
–Standard 4X15 W,
–Cabasse 4X40 W.
These systems enable the user to listen to AM/FM radio, CDs (MP3 CDs optional with the Cabasse system) and
satellite navigation voice messages.
7 - Seat belt warning light (Only on Laguna II phase 2).
Seat belt warning light lit on the display.

Fault finding - Role of components
Role of main components
●Display: displays various multimedia system data such as the station selected, time, CD listing and satellite
guidance information.
●Steering column control: allows the various system functions to be used via the steering wheel control.
●Speakers and tweeters: relay the sound from the multimedia system into the vehicle.
●CD changer: enables compact discs to be loaded and music to be relayed to the tuner-amplifier.
●AM/FM aerial: receives radio signals from various transmitters.
●GPS aerial: receives various data transmitted by satellites.
●Radio/navigation computer: manages the various multimedia system functions according to user requests and
transmits audio data to the vehicle via the speakers.
●Cartographic map DVD: loads maps into the navigation computer.
●AM/FM aerial amplifier: improves the reception of AM/FM signals.

3. Enter the CD changer unlocking code (depending on options)
–If there is a CD changer, and when CD0000 is displayed, enter the code of the removed 4R Radio Navigation
system.
–After the unlocking code has been entered, the 4R Radio Navigation computer is in customer mode.
Note:
Each time an incorrect code is entered, the waiting time doubles (maximum 32 minutes).

If faults DF024 No instrument panel multiplex signal and DF026 No fold-out unit
multiplex signal are present, run command VP005 Computer configuration to
reconfigure the system (see Configuration and programming).
Conditions for applying fault finding procedures to stored faults:
Apply this fault finding procedure if the fault reappears as present or stored after it has
been cleared and the ignition has been switched off and on again.
Special note:
Apply this fault procedure only for vehicles equipped with an instrument panel dot
matrix display (Top of the range Mégane II phase 2).
Use the Wiring Diagrams Technical Note for the Mégane II.
Look for any damage to the wiring harness, check the condition and connection of the connectors on
components 261 and 247.
Manipulate the wiring harness in order to produce a change in the fault status (present → stored).
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Using the universal bornier, check the insulation, continuity and the absence of interference resistance on
the following connections:
●connection code 107W,
●connection code 107X,
between components 261 and 247.
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.
If the fault is still present, run fault finding on the instrument panel (see 83A, Instrument panel) and the multiplex
network (see 88B, Multiplexing).
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the faults from the 4R radio navigation computer memory using command RZ001
