Fault finding – Introduction86D

Vdiag No.: 14
Faults
Faults are declared as either present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but have not been diagnosed within the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is used after the
+ after ignition feed has been switched on (without any of the system components being activated).
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 Notes section.
If the fault is confirmed when the instructions 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 the data that does not display a fault on the diagnostic tool when 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.
A synopsis of the general procedure to follow is provided on the following page in the form of a flow chart.

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.

CF007: Vehicle configuration (Carry out this configuration only if the vehicle is not equipped with a Navigation
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.

VP001: "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 computer of the multimedia connection unit
–Select the Repair mode menu.
–Select the Other parameters menu.
–Select line VP001 Write VIN.
–Enter the VIN.
–Exit fault finding mode.
–Switch off the ignition.
–Wait 5 seconds.
–Reread the VIN in the Identification menu for confirmation (ID008 VIN code).
SC002: Vehicle identifier (Only for New Twingo)
This command is used to obtain the vehicle identifier. The SC002 is used to read the "Vehicle ID" entered in the
instrument panel computer and to enter it in the multimedia connection unit and in the display. The vehicle identifier
is contained in this "Vehicle ID".
This command is to be used each time the computer is replaced. The radio will be locked if it does not read a correct
vehicle identifier.
