Subsection concerned: 01B

Using the Wiring Diagrams

Technical Note 3864A is an explanatory note for the use of wiring diagrams

on CD-ROM (Visu Schéma). The Technical Note helps in understanding how

Visu Schéma works and gives help in navigating and searching Visu

Schéma.

The Wiring Diagrams Technical Notes allow selection of the Applied Principle Diagram.

Marked by:

corresponding to a defective function.

Each diagram is marked according to the identification of the vehicle concerned, i.e.:

● the vehicle family (for instance, J64),

● the engine as described on the engine plate and the engine suffix (e.g. E7J 764),

● the date the vehicle was manufactured. On every Wiring Diagrams Technical Note there is a FROM WHICH

date which determines the production cut-off of the vehicles for which the Technical Note is valid,

more generally, the vehicle criteria (for example, left-hand drive, air conditioning).

A Quick Guide to Visu Schéma gives some tips on how to use the Visu Schéma software.

There will be little, or no, documentation on paper from 2004.

STRUCTURE OF THE TECHNICAL NOTE

1.1 The index of functions

This index allows the user to find the title of the corresponding function quickly from the number of a circuit diagram.

The index is listed in numerical order of the diagrams.

1.2 The diagrams

The diagrams section gathers together all the Applied Principle Diagrams.

The Applied Principle Diagrams show in detail the internals of simple components (switch, relay) and thus aid

understanding of the operation of the system and the fault finding routines. Here you will find:

● the components labelled with a number,

● the connectors, labelled with a letter followed by a number (R107),

● the earths, labelled with a letter followed by a number or a letter (e.g. M4 or MG).

The Applied Principle Diagrams are complemented by:

● the functions of the conductors on each connector (see ),

● the wiring routing, which allows the user to find the components on the vehicle,

● lists of criteria, components, junctions, earths, connections, allowing easy identification of all the

components on the diagrams.

Since version 2, it has been possible to print the diagrams directly to A3 format or to two A4 sheets, in colour or

black and white.

1.3 Fuse and relay boxes

The boxes section illustrates and describes in detail the various fuse and relay boxes on the vehicle. The following

are described for each vehicle:

● a graphical representation of the front and/or rear of the box,

● a list of fuses, their use, their position, their rating.

1.4 Earth location diagrams

The earth locations diagrams show and identify the location of the earthing points present on the vehicle.

1.5 Lists of parts

The lists of parts list and describe all the connectors used in the vehicle wiring harnesses. Each list of parts gives:

● a graphical representation of the connector (the representation may be simplified), and the assignment to

the pinouts in the connector,

● the list of conductors connected to the connector with their allocation to the pinouts,

● the cross-section of each conductor,

● the function of each conductor.

There is one list of parts per connector. The connectors are indexed in the lists provided on each Wiring Diagrams

Technical Note.

Conductor colours

● The basic electrical states are:

Red

+ 12 volts before ignition

Yellow

+ 12 volts after ignition

Blue

monitoring circuit or identifiers

Black

free earth

The following colours are used for the other conductors and the other connectors: white, blue, beige, clear,

grey, yellow, brown, black, orange, red, salmon pink, green, violet. These colours may vary for the same

wiring harness depending on the supplier.

White

Yellow

Red

Blue

Brown

Salmon pink

Beige

Black

Green

Clear or White

Orange

Violet

Grey

+ starter, intermittent earths, polarity inversions are not fundamental electrical states.

Protective devices (fuses and thermal cut-outs) do not change the electrical state of the conductors.

Wiring supplied with devices does not always follow these rules.

1.6 Wiring routing

● The wiring routings identify the location on the vehicle of devices, connectors and wiring routing points.

● In the wiring routing, the letter N indicates the label identifying the wiring.

IMPORTANT

The wiring routing points may be slightly modified and may vary from one vehicle to the next. Always check

the correctness of the routing before any work on the vehicle or before any operation liable to cause

damage to the wiring.

1.7 The lists

List of links: for identifying the function of a conductor from its code.

● List of components: for identifying a component on a diagram from its code.

● List of earths: for identifying an earth on a diagram from its code.

● List of connections: for identifying a connector on a diagram from its code.

● List of criteria: for identifying a criterion on a diagram from its abbreviation. The list explains the meaning in

non-abbreviated terms.

1.8 On-line help

On-line help assists in understanding the use of the Visu Wiring Diagram Technical Notes and is a complement to

the CBT.

USING THE TECHNICAL NOTE

2.1 How to read an Applied Principle Diagrams:

(a sample diagram is shown on the following page)

Vehicle family.

Criteria for the selection of the diagram.

Current year

Colour of the connector or the module if it is a module socket.

Representation of the connector (number of tracks marked on the front or rear of the connector).

Representation of the connection (square for a male connector and round for a female connector).

The connection will have a foolproofing device, and the colour is not necessarily the same for the male

and female parts.

Colour of the connection or the module socket.

Number of the board to which the device is connected.

Standardised device number

Fuse rating.

Position of the fuse on the board.

01B-3

VEHICLE FAULT FINDING TECHNICAL SPECIFICATIONS

General Information

01B

Colour of the module socket.

Number of the connection.

Name of the splice not located in the wiring routing.

Earth name (M for earth and N for neutral).

Secondary device.

Section number.

Sheet number.

Representation of a link.

Link code (for identifying the function of a conductor), see the list of links.

Pinout number.

Representation of a twisted conductor.

Representation of a shield.

Note:

The secondary device, in this diagram, supplies the signal to the computer which controls the relay. Refer to the

corresponding diagram for details of the link between the device and the computer.

Definition of selection criteria:

A characteristic of the criteria field is that a combination of criteria is permitted:

The / (forward slash) represents OR .

The , (comma) represents AND .

S or SS as the first letter(s) of a criterion mean WITHOUT or WITH .
