To cut off the + after ignition feed, proceed as follows:
Faults
Faults are declared 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 the faults should be taken into consideration when the diagnostic tool is used after
the + after ignition feed has been activated (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 faulty component,
–the condition of the wires (melted or cut insulation, wear). For vehicles with radio frequency remote control/key, use the key to switch off the ignition.
For vehicles with Renault cards,
Press the Start button twice briefly (less than 3 seconds),
Ensure that the + after ignition feed has been cut off by checking that the computer warning lights on the
instrument panel have gone out.

Conformity check
The purpose of the conformity check is to check data that does not produce 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 repair.
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 permitted tolerance values, you should 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 dealt with by
customer complaints.
A synopsis of the general procedure to follow is provided on the following page in the form of a flow chart.

4. FAULT FINDING PROCEDURE (continued)
4.1 Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring may temporarily clear 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 firmly secured.
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 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 Ω < X < 2 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
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.

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.
5. Visual inspection of the sealing:
(Only for watertight connectors)
Check for the seal on the connection (between the 2 parts of the connection).
–Check the seal at the back of the connectors:
–For unit joints (1 for each wire), check that the unit joints are present on each electrical wire and that they are
correctly positioned in the opening (level with the housing). Check that plugs are present on openings which
are not used.
–For a grommet seal (one seal which covers the entire internal surface of the connector), check that the seal
is present.
–For gel seals, check for gel in all of the openings without removing the excess or any protruding sections
(it does not matter if there is gel on the contacts).
–For hotmelt sealing (heat-shrink sheath with glue), check that the sheath has contracted correctly on the rear
of the connectors and electrical wires, and that the hardened glue comes out of the side of the wire.
–Check that there is no damage to any of the seals (cuts, burns, significant deformation, etc.).
If a fault is detected, consult Technical Note 6015A, Repairing electrical wiring.
