5. FAULT FINDING LOG
You will always be asked for this log:
–when requesting technical assistance from Techline,
–for approval requests when replacing parts for which approval is mandatory,
–to be attached to monitored parts for which reimbursement is requested. The log is needed for warranty
reimbursement, and enables better analysis of the parts removed.
6. SAFETY INSTRUCTIONS
Safety rules must be observed during any work on a component to prevent any material damage or personal injury:
–check the battery voltage to avoid incorrect operation of computer functions,
–use the proper tools. IMPORTANT!IMPORTANT
Any fault on a complex system requires thorough fault finding with the appropriate tools. The
FAULT FINDING LOG, which should be completed during the fault finding procedure, ensures a
record is kept of the procedure carried out. It is an essential document when consulting the
manufacturer.
IT IS THEREFORE COMPULSORY TO COMPLETE A FAULT FINDING LOG
EACH TIME IT IS REQUESTED BY TECHLINE OR THE WARRANTY RETURNS
DEPARTMENT.

1.DEF: Excess voltage
2.DEF: Undervoltage
NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the multimedia system has been switched on.
Special notes:
The undervoltage fault appears if the computer feed voltage is less than or equal to
7.5 V for at least 1 second.
The overvoltage fault appears if the computer feed voltage is greater than or equal to
18.5 V for at least 1 second.
Use the Wiring Diagrams Technical Note for Clio III or New Twingo.
For a vehicle equipped with a Navigation computer, use component 1714, Multimedia
connection unit, for fault finding on the Multimedia interface unit.
Otherwise use component 653, display computer.
1.DEF
NOTESNone.
Check the battery and perform an alternator supply test (see 16A, Starting, Charging).

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.

ALP 1 No dialogue with the computer
NOTESFor a vehicle equipped with a Navigation computer, use component 1714, Multimedia
connection unit, for fault finding on the Multimedia interface unit.
Otherwise use component 653, display computer.
Use the Wiring Diagrams Technical Note for Clio III or New Twingo.
Try to establish dialogue with a computer on another vehicle to check that the diagnostic tool is not faulty. If the
diagnostic tool is not causing the fault and dialogue cannot be established with any other computer on the same
vehicle, it may be that a faulty computer is disrupting the fault finding line.
Use a process of successive disconnections to locate this computer.
Check the battery voltage, component code 107, and perform the necessary operations to obtain the correct
voltage (12 V < X < 15 V).
Check the presence and condition of the computer supply fuses:
–for New Twingo: F48 (15 A),
–for Clio III: F14 (5 A), F2 (20 A) and unit fuse 710 (15 A).
Check the connection of the display connector, component code 653, or the multimedia connection unit connector,
component code 1714, and the condition of its connections.
If the connector(s) is 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.
Check that the computer is correctly supplied by checking 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(s) is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
