VOLVO

TP 3984202

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 VADIS.

• Certain components of the aforementioned systems must be grounded while working. Read the appropriate sections in VADIS.

• 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.

Modifications introduced up to August 2004

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.

Order number TP 3984202

This publication contains updated information for model year 2005 late version. For other electrical systems, see publication TP 3978202, available in Electronic Wiring Diagram (EWD) TP 3983002 or later.

We retain the right to make modifications.

The descriptions below apply in general to all wiring diagram manuals, although not all sections are necessarily contained 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 number, 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 respective type numbers refer to, for example, 3/x = switch, 6/x = electric motor, etc.

1 Battery 2Relay 3 Switch 4 Control module 5 Driver information module 6 Electric motor 7Sensor 8 Actuator 9 Heating element 10 Lamp 11 Fuse 15 Electrical distribution rail/box 16 Audio 17 Service/diagnostics 18 Contact reel 19 Meter 20 Ignition component/shunt 27 Optics 31 Ground connection 63 Junction point 64 Connector

B. Junction points

The wiring diagrams contain numbered junction points, e.g. 63/352.

This manual contains a section with a list of junction points. This list shows all the components that are connected to each junction point.

The location of the junction points is shown in the "Cable harness routing in vehicle" section.

C. Connectors

Connectors provide a bridge between two cable harnesses and are described in the "Connectors" section.

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 wiring diagram. Complete information on CAN and MOST communication is found in the section "Control modules".

F. Abbreviations

A number of different abbreviations are used in the manual. These are explained in the section "Abbr eviations".

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.
