4. FAULT FINDING PROCEDURE (continued)
4.1. Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring 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, insulators and wiring harness routing.
Look for signs of oxidation.
Physical inspection
While manipulating the wiring harness, use the diagnostic tool to note any change in fault status from stored to
present.
Make sure 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.
Checking earth insulation
This check is carried out by measuring the voltage (multimeter in voltmeter mode) between the suspect connection
and the 12 V or 5 V. The correct measured value should be 0 V.
Checking insulation against + 12 V or + 5 V
This check is carried out by measuring the voltage (multimeter in voltmeter mode) between the suspect connection
and the earth. In the first instance, the earth may be taken on the chassis. The correct measured value should be 0 V
Continuity check
A continuity check is carried out by measuring the resistance (multimeter in ohmmeter mode), with the connectors
disconnected at both ends. The expected result must be between: 0 ΩΩ Ω Ω
< X < 2 Ω for every connection. The line must
be fully checked, and the intermediate connections are only included in the method if this saves time during the fault
finding procedure. The continuity check on the multiplex lines must be carried out on both wires. The measured
value must be between: 0 ΩΩ Ω Ω
< X < 2 ΩΩ Ω Ω
.
Checking the supply
This check may be carried out using a test light (21 W or 5 W depending on the maximum authorised load)
4.2. Connector check
Note:
Carry out each requested check visually. Do not remove a connector if it is not required.
Note:
Repeated connections and disconnections alter the functionality of the connectors and increase the risk of poor
electrical contact. Limit the number of connections/disconnections as much as possible.
Note:
The check is carried out on the 2 parts of the connection. There may be two types of connection:
–Connector/Connector.
–Connector/Device.

Role of main components
–Multimedia network interface unit: enables information to be exchanged between the “vehicle” and “multimedia”
multiplex networks.
The multimedia network interface unit is integrated into the display computer on vehicles not equipped with a
navigation system.
If the vehicle is equipped with a navigation system, the multimedia network interface unit is a computer which is
independent of the display: the multimedia connection unit, located behind the glovebox on the passenger side.
The multimedia connection unit (Display or Multimedia connection unit) receives various signals from the vehicle
CAN (speed, status of exterior lights) and retransmits them for the radio via the Multimedia CAN.
The multimedia connection unit (Display or Multimedia connection unit) transmits the activation signal to the radio
and to the other computers participating in the multimedia function when the user switches on the radio or starts the
vehicle.
The multimedia connection unit is involved in the radio anti-theft protection system.
The protection is based on an identifier, the "Vehicle ID", sent on the CAN-V by the instrument panel computer. The
multimedia connection unit reads the "Vehicle ID" on the CAN-V and sends it to the CAN-M for the multimedia type
computers.
The multimedia connection unit allows the optimum configuration of the sound volume according to the vehicle
speed.
–Display: displays various multimedia system data such as the station selected, time, CD listing and satellite
guidance information.
–Radio control satellite: allows the different functions of the multimedia system to be accessed through the radio
control satellite.
–Radio/navigation computer: manages the various multimedia system functions according to user requests and
transmits audio data to the vehicle via the speakers.

General operation
The multimedia system is involved in the following functions:
–Radio reception (AM, FM).
–Playing CDs/MP3 CDs/navigation map.
–Guidance and navigation system with colour screen.
–Bluetooth hands-free phone.
The use of this multimedia system allows the customer:
–To select radio stations by using the preselections, the list or manual selection.
–To have an automatically-updated radio list.
–To listen to CDs or MP3 CDs.
–To control the radio using the radio control satellite.
–To change various acoustic parameters (bass, treble, fader, etc.).
–To navigate on a colour screen (visual and audio guidance): for this function the system uses GPS, the vehicle
speed wire information and an internal gyroscope.
–To receive traffic information via RDS-TMC and to display it on the navigation map.
–To display the time and temperature on the screen.
–To use the hands-free phone function (sound relayed to the radio speakers) with a Bluetooth phone.
–To be protected by an immobiliser code.

system).
This command is used to configure the computer according to the vehicle equipment.
After having performed CF007, perform CF012 Lighting.
CF008: Radio
This command is used to configure the computer according to the vehicle equipment.
Reread the configuration LC004 Radio in the Read configuration menu to confirm that the change was correctly
accepted.
CF009: Navigation (Only for Clio III).
This command is used to configure the computer according to the Navigation equipment of the vehicle.
Only use this command on a vehicle equipped with navigation.
CF012: Lighting (Carry out this configuration only if the vehicle is not equipped with a Navigation system)
This command, on New Twingo, is used to configure the luminosity level of the display screen by selecting the type
of radio.
This command, on Clio III, is used to configure the luminosity level of the display screen by selecting the type of
radio, and to confirm the option with or without dimmer.
NOTE: The two types of radio can be distinguished as follows: radio R02 has a telephone button, radio R01 does
not.
