Wiring diagram 2008 Supplement
VOLVO C30, S40, V50 & C70
TP 39126202

© Volvo Car Corporation
Vehicles with SRS (Airbag)/SIPS bag/IC
(Inflatable Curtain)
Warning!
Extra caution must be exercised when working on vehicles equipped with SRS/SIPS bag/IC
in order to avoid:
1. Personal injuries when performing repair work.
2. Damage or malfunction of the SRS/SIPS bag/IC system.
Work involving the SRS/SIPS bag/IC systems or other components in the vehicle that may
affect the SRS/SIPS bag/IC systems must always be performed by an authorized Volvo
workshop.
In case of doubt, consult the SRS and SIPS bag/IC service manual.
Is the vehicle equipped with SRS/SIPS bag/IC?
Vehicles with SRS are most easily recognized by the letters SRS in the center of the steering
wheel. If the vehicle also has a passenger side airbag, the letters SRS are stamped on the
dashboard above the glove compartment. SRS vehicles from 1993 and onward also have
explosive seat belt tensioners. SIPS bags are only installed on SRS vehicles from 1995 and
onward. SIPS bag decals are located on the windshield and seat compartment. Vehicles with
IC can be recognized by the letters IC on the C/D panel (4 door) or the B panel (5 door).
General recommendations
• Be especially careful when working on or around SRS, SIPS, and IC components.
• Make sure that no wires are pinched, frayed, or pierced.
• Never install accessories by the sensors.
• Where applicable, work on the steering wheel, steering shaft, or steering gear must be done
in accordance with the methods in the SRS section of VIDA.
• Certain components of the aforementioned systems must be grounded while working. Read
the appropriate sections in VIDA.
• Install no accessories in the areas between the A and B posts, the B and C posts, and the
C and D posts.
Test terminal
Data link connector in the passenger compartment.
Changes introduced up to and including October 2008
Any changes made to the vehicles after this date are not included in the
manual. If necessary refer to service bulletins.
Volvo models are sold in versions adapted for different markets. These
adaptations depend on factors such as legal requirements, taxation, and
market demands.
This manual may therefore include illustrations and text that do not apply to
the vehicles in your country.

The descriptions below apply in general
to all wiring diagram manuals, although
not all sections are necessarily con-
tained in this manual.
How to use the wiring diagrams 1:2
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.

63 Branching point
64 Connector
B. Branching points
The wiring diagrams contain numbered junction
points, e.g. 63/352.
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 and MOST networks that
transfer information. Connections to these networks
are not shown in their entirety in the respective wir-
ing diagram. Complete information on CAN and
MOST communication is found in the section "Con-
trol 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.
