How to use the wiring diagrams 1:2
The descriptions below apply in general
to all wiring diagram manuals, although
not all sections are necessarily con-
tained in this manual.
A. Component designation
Every component has a component designation that
consists of two parts.
The first part is a type number that describes the
type of component in question, for example 3/xx.
The second part of the designation is a serial num-
ber, e.g. x/2.
Together, this constitutes a component designation,
e.g. 3/2.
At the end of the manual is a list of components,
where, with the help of the component designation,
you can read off the name of the component, for
example, 3/2 = light switch.
List of type numbers
The list shows which type of component that respec-
tive type numbers refer to, for example, 3/x = switch,
6/x = electric motor, etc.

74
Connector
The systems are shown in non-active
status. i.e. with "key removed" and when
the doors, hatches and hood are closed.
B. Branching points
The wiring diagrams contain numbered branching
points, for example 73/5035.
This manual contains a section with a list of branch-
ing points. This list shows all the components that
are connected to each branching point.
The location of the branching points is shown in the
"Cable harness routing in vehicle" section.
C. Connectors
Connectors provide a bridge between two cable har-
nesses and are described in the "Connectors" sec-
tion.
D. Electrical distribution
Operation of the fuses and relays is shown in the
"Electrical distribution" section.
E. Data communication
Today's cars contain CAN, LIN and MOST networks
that transfer information. Connections to these net-
works are not shown in their entirety in the respec-
tive wiring diagram. Complete information on CAN,
LIN and MOST communication is found in the sec-
tion "Control modules".
F. Abbreviations
A number of different abbreviations are used in the
manual. These are explained in the section "Abbre-
viations".
G. Component location
There is a section at the end of the manual in which
the appearance and location of components is
described in numerical order.
