4. FAULT FINDING PROCEDURE (continued)
4.1. 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
When handling the wiring, use the diagnostic tool to detect any change in the status of the fault 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.
Checking earth insulation
This check is carried out by measuring the voltage (multimeter in voltmeter mode) between the suspect connection
and the 12 V or 5 V. The correct measured value is 0 V.
Checking insulation against + 12 V or + 5 V
This check is carried out by measuring the voltage (multimeter in voltmeter mode) between the suspect connection
and the earth. In the first instance, the earth may be taken on the chassis. The correct measured value should be 0 V
Continuity check
A continuity check is carried out by measuring the resistance (multimeter in ohmmeter mode), with the connectors
disconnected at both ends. The expected result must be between: 0 ΩΩ Ω Ω
< X < 2 Ω for every connection. The line must
be fully checked, and the intermediate connections are only included in the method if this saves time during the fault
finding procedure. The continuity check on the multiplex lines must be carried out on both wires. The measured
value must be between: 0 ΩΩ Ω Ω
< X < 2 ΩΩ Ω Ω
.
Checking the supply
This check may be carried out using a test light (21 W or 5 W depending on the maximum authorised load)

4.2. Connector check
1. Visual inspection of the connection:
–Check that the connector is connected correctly and that the male and female parts of the connection are
correctly coupled.
2. Visual inspection of the area around the connection:
–Check the condition of the mounting (pin, strap, adhesive tape, etc.) if the connectors are attached to the
vehicle.
–Check that there is no damage to the wiring trim (sheath, foam, adhesive tape, etc.) near the wiring.
–Check that there is no damage to the electrical wires at the connector outputs, in particular on the insulating
material (wear, cuts, burns, etc.).
Disconnect the connector to continue the checks.
3. Visual inspection of the plastic casing:
–Check that there is no mechanical damage (casing crushed, cracked, broken, etc.), in particular to the fragile
components (lever, lock, openings, etc.).
–Check that there is no heat damage (casing melted, darker, deformed, etc.).
–Check that there are no stains (grease, mud, liquid, etc.).
4. Visual inspection of the metal contacts:
(The female contact is called CLIP. The male contact is called TAB).
–Check that there are no bent contacts (the contact is not inserted correctly and can come out of the back of the
connector). The contact comes out of the connector when the wire is gently pulled.
–Check that there is no damage (folded tabs, clips open too wide, blackened or melted contact, etc.).
–Check that there is no oxidation on the metal contacts. Note:
Carry out each requested check visually. Do not remove a connector if it is not required.
Note:
Repeated connections and disconnections alter the functionality of the connectors and increase the risk of poor
electrical contact. Limit the number of connections/disconnections as much as possible.
Note:
The check is carried out on the 2 parts of the connection. There may be two types of connection:
–Connector/Connector.
–Connector/Device.

The mobile connectivity computer enables music files to be played (MP3, WMA, etc.) on:
•USB mobile peripherals (USB key, MP3 player, etc.) (Except hard disk with own power supply),
•audio peripherals via the jack socket.
The multimedia system offers the following possibilities:
•Choose FM radio stations using the presets, the list or manual selection.
•Have access to an automatically updated FM radio list.
•Listen to CDs and MP3s.
•Control the radio using the radio control satellite.
•Have access to optimised audio and acoustic telephone configurations for each vehicle according to the vehicle
type.
•Modify various acoustic parameters (base, treble, front/rear balance, etc.).
•Use the hands-free telephone function (sound relayed towards the radio speakers) with a Bluetooth telephone.
•Use voice recognition for the telephone functions (button on the radio control satellite). The voice identifier can be
recorded.
•Benefit from a connection for a CD changer.
•Possibility of connecting a peripheral with a USB port, Jack socket, etc.
•Has anti-theft protection
Computer activation system
The mobile connectivity computer has an activation system.
The mobile connectivity computer is activated under the following conditions:
•by pressing the radio ON/OFF button,
•by starting the engine.
The mobile connectivity computer is switched off under the following conditions:
•The ignition is switched off.
•Door opened (Clio III)
•Door opened for 1 minute (New Twingo)
•By pressing the radio ON/OFF button (Clio III and New Twingo).
The multimedia connection unit (Display or Multimedia connection unit ) is activated by the UCH (central door
unlocking); this then activates the multimedia computers (Navigation, Radio, mobile connectivity computer, etc.) via
the "Activation signal" connections.
