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.

EXTERNAL TEMPERATURE
NOTESOnly apply the checks if the parameter is inconsistent.
There must be no present or stored faults.
Special notes:
On the Laguna, Trafic, Master and Master propulsion, the exterior temperature
information is supplied by the exterior temperature sensor.
On Mégane and Scénic, this information comes from the UCH.
Use the Wiring Diagram Technical Note for the vehicle concerned.
Only for Laguna, Trafic, Master and Master propulsion
Check the condition and connection of the connector of component 240 (component 239 for right-hand drive
vehicles) and the black 24-track connector of component 261 (Trafic: 662).
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:
Left-hand drive:
●47C connection code,
●47D connection code,
between components 261 (Trafic: 662) and 240.
Right-hand drive:
●47C connection code,
●connection code 47D,
between components 261 (Trafic: 662) and 239.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRRepeat the conformity check from the start.

Only for Mégane II ph 2 and Scénic II ph2
Check the condition and connection of the connector of component 645 and the black 24-track connector of
component 261.
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
connection 47Z (Mégane) or 47C (Scénic) between components 261 and 645.
If the connection is 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, apply the fault finding procedure for the UCH system (see 87B, Passenger compartment
connection unit).
AFTER REPAIRRepeat the conformity check from the start.
