Fault finding problems
Disconnecting the connectors and/or manipulating the wiring harness may temporarily remove the cause of a fault.
Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulation and wiring harness routing.
Look for signs of oxidation.
Tactile inspection
While manipulating the wiring harness, use the diagnostic tool to note any change in fault status from stored to
present.
Check that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the holes.
Check that no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or to another wire.
If a fault is detected, repair or replace the wiring harness.

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 - Replacement of components
For removing/refitting the 4R radio navigation computer, refer to the MR for the vehicle concerned:
Mégane II ph2
(see MR 364 mechanical, 83C On-board telematics system, Computer: Removal - Refitting)
Laguna II ph2
(see MR 395 mechanical, 83C On-board telematics system, Computer: Removal - Refitting)
Scénic II ph2
(see MR 370 mechanical, 83C On-board telematics system, Computer: Removal - Refitting)
Trafic II ph1 and ph2
(see MR 408 mechanical, 83C On-board telematics system, Radionavigation: Removal - Refitting)
Master ph2 and ph3
(see MR 377 mechanical, 83C On-board telematics system, Radionavigation: Removal - Refitting)
Master propulsion ph2
(see Technical Note 3818A, 83C, On-board telematics system, Radionavigation: Removal - Refitting)
Operations to be carried out before replacing the 4R radio navigation computer:
1. Before replacing the 4R radio navigation computer (with Techline approval), perform a fault read and a conformity
check to confirm that it is faulty.
2. Before removing, eject the CD.
3. Following Techline approval, remove the computer, with the ignition off (wait 1 minute for the system to shut
down completely).
The 4R radio navigation computers available from the Parts Department are supplied unconfigured and with a black
screen.
Operations to be carried out before replacing the 4R radio navigation computer:
1. Configure the computer (see Configuration and programming).
The 4R Radio Navigation computer is in factory mode following configuration (87.5 MHz FM in scrambled mode for
2 minutes).
2. Enter the 4R Radio Navigation system unlocking code
Obtaining the 4R Radio Navigation system unlocking code:
–switch on + after ignition feed (see introduction),
–if the 4R Radio Navigation system does not come on when the + after ignition feed is activated, press the
ON/OFF button on the front panel,
–connect the Clip diagnostic tool,
–note the programming key number ID012 Navigation programming key indicated in the identification menu,
–Consult Renault.net with the programming key number to obtain the 4R Radio Navigation system unlocking
code. In the event of a fault, contact the Techline,
–2 minutes after the 4R Radio Navigation system is switched on, the unlocking code is requested,
–enter the code using the radio control satellite under the steering wheel.

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).

VEHICLE SPEED
NOTESThere must be no present or stored faults.
Use the Wiring Diagram Technical Note for the vehicle concerned.
Run fault finding on the ABS system (see 38C, Anti-lock braking system).
If there is no ABS system fault indicated, check connection 47F between components 1094 and 261 (Trafic: 662).
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, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.
