How to read the diagrams
Definition of an illustration
The diagram consists of several plates.
The plates are defined in the bottom right-hand corner by:
– a six-figure number, which is the reference number of the illustration.
– a letter, which is the revision index of the illustration. This letter is to be found on the same line as the
reference number.
– a three-figure number, which defines the folio number.
A diagram plate is broken down into 5 zones in the vertical direction.
These zones are identified by letters ranging from A to E.
Definitions of symbols used in a diagram
Cross-references
The folio co-ordinates to be found on the right always refer back to
a preceding page.
The folio co-ordinates to be found on the left always refer forward to
a following page.
The cross-reference is defined by:
– a three-figure number, which gives information on the order
number of the destination folio,
– a letter, which gives information on the zone in which the
cross-reference is to be found.

Appliances
Each appliance shown in the diagram is identified by an after-sales
code number.
If the after-sales code number is framed (item (1) of the illustration
opposite), it indicates a single appliance or an assembly comprising
several functions.
If the after-sales code number is not framed (item (2) of the illustration opposite), it indicates a single appliance. It is then to be found
inside the symbol.
Underneath each appliance, we define, wherever possible, the
colour and the number of ways of the connector with which it is
associated (item (3) of the illustration opposite).
All the terminals of each appliance are defined by a numerical or
alphanumerical code number, if necessary (item (4) of the illustration opposite).
For certain appliances, we define, wherever possible, the power with which it is associated (item (5) of the illustration opposite).
Fuses and relays
A-5
Relays are designated by an after-sales code number (item (1) of
the illustration opposite).
They are also designated by an alphanumerical code number and
by the value of the rated current capable of crossing them
(item (2 - 3) of the illustration opposite).
Fuses are merely designated by an alphanumerical code number
and by the value of the rated current capable of crossing them.
Polarities
Polarities are identified by a numerical code number.
For each function, there is one same, single code number.
Example:
2 = battery "positive" direct current power supply.
1 = earth.
Circuits where polarities are represented by dotted lines indicate a connection solution or an optional assembly.
RENAULT V.I. 11/2003
A-6
Graphic conventions
A folio cross-reference can consist of two sections.
The first in a zone of the diagram (item (1A) of the illustration above).
The second to the right or left of the zone of the diagram according to its destination (item (1B) of the illustration
above).
In all cases, both sections are always on the same line.
This principle is applied whenever it makes it possible to avoid polarity crossovers that may prejudice clear
legibility of the diagram.
A folio cross-reference may be made by fuse (5) or by warning light (4).
If an intersection is not reinforced by a connection point, the polarities cross over and are distinct (3).
If an intersection is reinforced by a connection point, we have the same level of information on the wires (same
potential)
It is possible for extra connection points to be applied to the diagram for legibility reasons (item (2) of the
illustration above).
70 139
It is possible for a function to have several technical responses.
In this case, we call upon the notion of "variant" or "option".
This notion is represented by a figure inside a circle. This symbol is
placed on the polarity in question.
An explanation to be found on the page opposite the diagram
describes the possible options.
If a folio represents several assemblies, it goes without saying that
a vehicle can have only one single option.

To make for easier reading, communication buses are represented
as follows:
Only the ends of conductors are represented (item (1) of the illustration opposite).
The "body" of the wiring harness is shown in diagrammatic form by
one thicker single line. Page cross-references are made according
to the same principle as for polarities (item (2) of the illustration
opposite).
A-7
Wiring harnesses
Each plate represents the routing of one or several wiring harnesses connected to a sub-assembly or function.
The outline of the vehicle pinpoints the wiring harnesses.
Connectors identified by the letter "C" followed by figures are indicated on each harness.
A key opposite each plate defines their assignment.
The detail of the connectors connected to wiring harnesses on the plate enable the polarity of each pocket to be
situated.
Key to connectors:
C129 ................................4618 - Driver's overhead lamp
C129: connector item number
4618: appliance reference number
Driver's overhead light: key to the apparatus
The appliance reference number and key provide the link to the electrical diagram.
Optional wiring harnesses:
Connectors assigned with indexes "*1" or "*2" belong to optional harnesses.
Example of connector reference number:
C129: connector on standard harness
C137
C141
At the end of the key is shown the make-up of each optional harness.
: connector on option 1 harness
*1
: connector on option 2 harness
*2
Detail of connectors:
Each drawing represents the structure of a connector.
Example:
A: Outline of the connector
B: Item number and location of the wires
C: Reference number of the appliance
D: Item number of the connector
E: Option and/or colour of the connector

Electrical distribution
The cab electrical distributing box contains the majority of the fuses and relays necessary for operation of the
vehicle.
Fuses and relays that are connected on the electrical distribution box are represented as surrounded by a fine
dotted line in the electrical diagram.
Each face of the electrical distribution box is detailed in the "Electrical distribution unit" chapter.
The chassis-cab connection box enables the information to be found inside the cab to cross the bulkhead and
be routed to the outside and vice versa.
Each connector of the chassis-cab connection box is detailed in the "Electrical distribution unit" chapter.
Precautions to be taken when making electrical measurement readings
Protection of appliances
Bearing in mind the presence of numerous electronic appliances, the use of a test lamp is to be
avoided. Preferably use a needle or digital type multi-meter.
It is forbidden to apply voltage to the terminals of electronic appliances or you may cause
irreparable damage to the hardware. Consequently, no line continuity measurement should be
made on the wires without having previously disconnected the appliances from the lines
concerned.
