How to use the wiring diagrams 1:2

TP3990201 S40 (04-)/V50 2006 6

The descriptions below apply in general to all wiring diagram manuals, although not all sections are necessarily contained in this manual.

A. Component designationEvery 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 numbersThe list shows which type of component that respec-tive type numbers refer to, for example, 3/x = switch, 6/x = electric motor, etc.

1 Battery2 Relay3 Switch4 Control module5 Driver information module 6 Electric motor7 Sensor8 Actuator9 Heating element10 Light11 Fuse15 Electrical distribution rail/box16 Audio17 Service/diagnostics18 Contact reel19 Meter20 Ignition component/shunt27 Optics31 Ground connection63 Branching point64 Connector

B. Branching pointsThe wiring diagrams contain numbered junction points, e.g. 63/352.

This manual contains a section with a list of branching 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. ConnectorsConnectors provide a bridge between two cable harnesses and are described in the "Connectors" section.

D. Electrical distributionOperation of the fuses and relays is shown in the "Electrical distribution" section.

E. Data communicationToday’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. AbbreviationsA number of different abbreviations are used in the manual. These are explained in the section "Abbreviations".

G. Component locationThere is a section at the end of the manual in which the appearance and location of components is described in numerical order.
