Fault finding - Introduction
1. SCOPE OF THIS DOCUMENT
This document presents the fault finding procedure applicable to all computers with the following specifications:
2. PREREQUISITES FOR FAULT FINDING
Documentation type
Fault finding procedures (this manual):
–Assisted fault finding (integrated into the diagnostic tool), Dialogys.
Wiring Diagrams:
–Visu-Schéma (CD-ROM),
Type of diagnostic tools
–CLIP + multiplex line probe
Special tooling required
3. RECAP
For commercial vehicles, fault finding can only be run on the 4R Radio Navigation Computer by clicking on the Fault
finding - NAV4R Central Communication Unit - Commercial vehicles icon in the Help directory on the CLIP computer
desktop.
To run fault finding on the vehicle's computers,
Proceed as follows, depending on the type of equipment:Vehicle(s): Mégane II ph2, Master ph2 and ph3,
Master propulsion ph2 and ph3, Laguna II ph2,
Trafic II ph1 and ph2, Scénic II ph2
Function concerned: 4R Radio NavigationName of computer: 4R Radio Navigation

For vehicles with radio frequency remote control/key,
switch on the ignition with the key.
For vehicles with a Renault card,
to save energy, the vehicle's UCH cuts off the + after ignition feed after a certain period of time. It is essential to
force the + after ignition feed by applying the following procedure:
–with the vehicle card in the card reader,
–press and hold (5 seconds +) the Start button with starting conditions not fulfilled until the diode on the instrument
panel starts to flash rapidly,
–connect the diagnostic tool and perform the required operations.

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).

Fault finding - Configuration and programming
SETTINGS
VP002 Write VIN:
This command permits manual entry of the vehicle's VIN into the computer. Use this command each time the
computer is replaced. The VIN number is inscribed on the manufacturer's plate.
Procedure for writing the VIN
●Establish dialogue with the navigation computer.
●Select the repair mode menu.
●Select the other parameters menu.
●Select line VP002 Enter VIN.
●Enter the VIN.
●Exit fault finding mode.
●Switch off the ignition.
●Wait for the end of power latch.
●Reread the VIN in the identification menu to confirm (ID011 VIN code).
VP005 Computer configuration:
This command is used to configure the 4R radio navigation computer by entering the vehicle type and the trim level.
When the command is complete, switch off the ignition, wait 2 minutes and switch on the ignition again. Check that
the configuration has registered correctly by reading configurations LC001 Vehicle type and LC005 CD changer.
The radio is in factory mode after configuration (FM 87.5 MHz in scrambled mode for 2 minutes).
PROGRAMMING
There is no programming on the navigation system.
