XC90 FWD L6-3.2L VIN 96 B6324S2 (2010)
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 information 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.

The systems are displayed in non-active status, i.e. in the event of "key removed" and when doors, trunk lid/tailgate and hood are closed.
B. Branching points
The wiring diagrams contain numbered junction points, e.g. 53/352.
This information 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" in Vehicle Level Harness Locations images.
C. Connectors
Connectors provide a bridge between two cable harnesses and are described in the "Connectors" in Vehicle Level Connector views.
D. Electrical distribution
Operation of the fuses and relays is shown in the "Electrical distribution" in Power and Ground Distribution Diagrams.
E. Data communication
Today's cars are equipped with CAN, LIN & MOST networks that transmit information. Connections to these networks are not shown in their entirety on
the respective wiring diagram. Complete information on Data communication can be found "Control modules" in Information Bus.
F. Abbreviations
A number of different abbreviations are used in the information. These are explained in "Wire Color Code and Other Abbreviations".
