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

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.

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.

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.
