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.

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.

NOTESOrder of priority in the event of more than one fault:
Deal with fault DF001 Computer first, if present or stored.
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:
If the vehicle does not have a CD changer, check the 4R radio navigation computer
configuration (see Configuration and programming).
Apply the following fault finding procedure to vehicles equipped with a CD changer.
Use the Wiring Diagram Technical Note for the vehicle concerned.
Look for any damage to the wiring harness, check the condition and connection of the connectors on
components 261 and 1272.
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 34AZ,
●connection code 34BA,
●connection code 34BL,
●connection code 34BC,
●connection code 34BD,
●connection code 34BG,
●connection code 34BH,
●connection code 34BK (only for Scénic),
between components 261 and 1272.
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, contact the Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the faults from the 4R radio navigation computer memory using command RZ001
Fault memory.

The system enables:
–CD-ROM maps to be displayed,
–the user to listen to commercial audio CDs, CDs burned independently, CDs
containing MP3 files (optional). The CDs are read by the 4R unit's CD player or by
the optional 6-CD changer.
Check that the CD is not scratched.
For a CD-ROM card, change the CD.
For all other types of CD, check that the CD format is compatible with the system.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the faults from the 4R radio navigation computer memory using command RZ001

RADIO FIELD INTENSITY
NOTESThere must be no present or stored faults.
Engine stopped, ignition on.
Tune to a known FM or AM station with the vehicle in an open area if possible.
The "Radio field intensity" corresponds to the electrical intensity of the radio signal (FM or AM) received at the
radionavigation tuner input, at the frequency currently selected. It is expressed in dB µV.
It gives an indication of the radio reception level. Below 18 dB µV, the station is considered weak and does not
appear in the list of radio stations.
A low value (< 18 dB µV) on this parameter means that:
–Either the selected station has a weak transmission in the geographical area. This may be due to the
distance from the selected station's transmitter (far from urban area, on motorways) or obstacles interfering
with the transmission of radio waves (mountainous areas, buildings, deep valleys).
–Or, if the reception conditions are good in the geographical area for the selected station, there is a fault on
the vehicle's reception system: one of the components (aerial/aerial amplifier/coaxial connection/radio aerial
connector) is faulty. In this case, refer to ALP 4.
This parameter may be used to compare two vehicles in order to determine if there actually is a vehicle fault.
