5. FAULT FINDING LOG
You will always be asked for this log:
–when requesting technical assistance from the Techline,
–when requesting approval before replacing parts for which approval is compulsory,
–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
All faults involving a complex system call for thorough diagnostics 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 ESSENTIAL THAT THE FAULT FINDING LOG IS FILLED OUT EVERY TIME IT IS
REQUESTED BY TECHLINE OR THE WARRANTY RETURNS DEPARTMENT.

1.DEF: Overvoltage.
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 Espace IV Phase 2 or Scénic II
Phase 2.

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, component
code 107.
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 F15 (30 A) for Espace IV Phase 2 or fuse SHUNT (2AA) for Scénic II Phase 2.
Check the connection and condition of the connectors of the multimedia network interface unit computer,
component code 1714, depending on the vehicle equipment.
If any connectors are faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connectors, otherwise replace the wiring.
Disconnect the computer connector and check the conformity of the following connections:
•BP3A between components 260 and 1714 (for Espace IV Phase 2),
•BCP3 between components 260 and 1714 (for Scénic II Phase 2),
•BPT between components 645 and 1714 (for Scénic II Phase 2),
•MAN between component 1714 and earth (for Scénic II Phase 2),
•NC between component 1714 and earth (for Espace IV Phase 2).
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
NOTESUse the Wiring Diagrams Technical Note for Espace IV Phase 2 or Scénic II
Phase 2.
Important: After switching on the system, there can be a delay of 20 seconds before
dialogue is established.
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 Espace IV Phase 2: F15 (30 A),
–for Scénic II Phase 2: SHUNT (2AA).
Check the connection of the multimedia network interface unit connector, component code 1714 and the condition
of its connections.
If the connector is faulty and there is a repair method (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:
•BP3A between components 260 and 1714 (for Espace IV Phase 2),
•BCP3 between components 260 and 1714 (for Scénic II Phase 2),
•BPT between components 645 and 1714 (for Scénic II Phase 2),
•MAN between component 1714 and earth (for Scénic II Phase 2),
•NC between component 1714 and earth (for Espace IV Phase 2).
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.
