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.

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.

For information on removing and refitting the multimedia connection unit of the multimedia network, refer to the
repair manual for the vehicle concerned:
If the vehicle is equipped with a Navigation computer (Only on Clio III):
See MR 392, Mechanical, 83C, On-board telematics system, Multimedia network interface unit: Removal -
Refitting.
If the vehicle is not equipped with a Navigation computer:
Clio III: See MR 392, Mechanical, 86A, Radio, Display: Removal - Refitting.
New Twingo: See MR 411, Mechanical, 86A, Radio, Display: Removal - Refitting.
Operations to be carried out before replacing the multimedia network interface unit:
1- Before replacing the multimedia connection unit (with Techline approval), read the faults and carry out a
conformity check to check that it is actually defective.
2-After obtaining Techline approval, remove the multimedia connection unit, with the ignition off (wait 1 minute for
the system to shut down completely).
The multimedia network interface units available from the Parts Department are supplied unconfigured.
Operations to be carried out after replacing the multimedia connection unit:
–Connect the diagnostic tool and switch on the system, then establish dialogue with the computer.
–Configure the multimedia connection unit (see Configurations and Programming).
–Configure the computer using command CF007 Vehicle configuration, then perform CF012 Lighting. Only carry
out these configurations on vehicles not equipped with a Navigation system. (see Configurations).
–If a radio is present, configure the computer using command CF008 Radio (see Configurations).
–If a Navigation system is present, configure the computer using command CF009 Navigation (see
Configurations).
–Enter the VIN code using command VP001 Write VIN (see Programming).
–Check that there are no faults and that the multimedia system is operating correctly. Note:
If the radio and the multimedia connection unit (BIC) are replaced simultaneously, the multimedia
connection unit must be configured first (see Configurations and Programming).

2.DEFNOTESNone.
Remove the card from the reader or the key from the ignition, then check the condition of the battery.
Check the battery: leaks, incorrectly fitted, loosened battery terminal, and corrosion.
Check the earth connections of the vehicle: battery/chassis, engine/chassis, starter/engine, alternator/engine,
gearbox/chassis.
If the fault is detected, resolve the abnormal contact fault.
Check the battery and perform an alternator supply test (see 16A, Starting, Charging).
Check the condition of fuse F48 (15 A) for New Twingo or fuses F14 (5 A), F2 (20 A), and unit fuse 710 (15 A) for
Clio III.
Check the connection and condition of the connectors of the display computer, component code 653 or of the
multimedia connection unit computer, component code 1714, depending on the vehicle equipment.
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Disconnect the computer connector and check the conformity of the following connections:
–BCP4 between components 260 and 653 or 1714,
–BPT between components 645 and 653 or 1714,
–BPT3 between components 260 and 653 or 1714,
–NAM between component 653 or 1714 and earth.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
