B. Junction points
The wiring diagrams contain numbered junction points, for example 53/352.
This information contains a section (Junction Points Diagrams) with a list of junction points. This list shows all the components that are connected to
each Junction point. See: Power and Ground Distribution/Branching Point/Diagrams/Electrical Diagrams
The location of the junction points is shown in the Vehicle Level Harness Locations images. See: Locations/Harness Locations
C. Connectors
Connectors provide a bridge between two cable harnesses and are described in the Vehicle Level Connector Views. See: Diagrams/Connector Views
D. Electrical distribution
Operation of the fuses and relays is shown in the "Power and Ground Distribution Diagrams". See: Power and Ground Distribution/Diagrams/Electrical
Diagrams
E. Data communication
Today's cars are equipped with CAN & MOST networks that transmit information. Connections to these networks are shown in their entirety in the
respective wiring diagram. Complete information on CAN & MOST communication can be found in the "Information Bus". See: Powertrain
Management/Computers and Control Systems/Information Bus/Diagrams/Electrical Diagrams
F. Abbreviations
A number of different abbreviations are used in the diagrams. These are explained in the "Wire Color Code And Other Abbreviations". See:
Diagrams/Diagram Information and Instructions/Wire Color Code Identification and Other Abbreviations
G. Component location
The appearance and location of components is described in alphabetical order at the Vehicle Level component locations A - Z Component List. See:
