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, 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.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Check that no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or with another wire.
If a fault is detected, repair or replace the wiring harness.

SVT computer:
For MEGANE II and SCENIC II:
With its attached support, it is bolted on the existing support of the dashboard cross member.
For MASTER II ph2 and ph3, THALIA 2/SYMBOL 2, CLIO II F6, KANGOO VLL:
The computer support is bolted on the existing support of the dashboard cross member.
For LOGAN, SANDERO and DUSTER:
The computer support is welded to the dashboard cross member.
The anti-theft tracking unit (computer) consists of:
– An integrated GPS aerial to locate the vehicle.
– An integrated GSM aerial to communicate with a call centre.
–A locking system that prevents the vehicle from operating when the owner of the vehicle declares to the call
centre that the vehicle has been stolen.
–An external GPS aerial can be connected to the anti-theft tracking unit, on certain vehicle types.

For LOGAN, SANDERO, DUSTER, MASTER II ph2 and ph3, THALIA 2/SYMBOL 2, CLIO II F6, KANGOO VLL:
The computer can switch off the electrical supply of the transponder ring. When the anti-theft tracking unit receives a
locking order from the call centre via the GSM network, it switches off the supply of the transponder ring.
For MEGANE II and SCENIC II:
For "no hands-free opening" vehicles, the computer can switch off the electrical supply of the card reader. When the
anti-theft tracking unit receives a locking order from the call centre via the GSM network, it switches off the supply of
the card reader.
For "hands-free opening" vehicles, the computer can switch off the electrical supply of both the card reader and the
steering column lock. When the anti-theft tracking unit receives a locking order from the call centre via the GSM
network, it switches off the supply of these two components.
The computer has several operating modes:
–NOT FUNCTIONING mode: The computer is not supplied. No function is available, but the system retains the
stored configuration and the recorded data.
–DEACTIVATED mode: The ignition is off. The computer is supplied by the vehicle battery. Vehicle tracking by
the call centre is not activated and the GSM network does not send the vehicle position to it. The computer
stores the satellite position in its memory every 24 hours.
–FUNCTIONING WITHOUT TRACKING mode: Ignition on. The computer is supplied by the vehicle battery.
Vehicle tracking by the call centre is not activated. The computer is registered on the GSM network in case
tracking is activated. The GSM network does not send the vehicle position to the call centre. The computer
stores the satellite position in its memory every minute.
–DEACTIVATED WITH TRACKING mode: The ignition is off. The computer is supplied by the vehicle battery.
Vehicle tracking by the call centre is activated. The computer sends the vehicle position message to the call
centre every 24 hours. Each time the computer is activated, it makes a record on the GSM network and
communicates it to the call centre, but does not store it in its memory.
–FUNCTIONING WITH TRACKING mode: Ignition on. The computer is supplied by the vehicle battery. Vehicle
tracking by the call centre is activated.
The computer sends the vehicle position message to the call centre every minute. The computer stores in its
memory all operations ordered by the call centre.
–VIOLATION mode: The computer is supplied by its internal battery. The computer sends the vehicle position
message to the call centre every minute. The main supply (+ Battery) is switched off. The GPS module is
activated after a position violation is detected.
–FAULT FINDING mode: The computer is supplied by the vehicle battery or by its internal battery. The computer
communicates with the diagnostic tool.
