Wiring Diagrams

When selecting a component in the ranked list, the relevant wiring diagrams are displayed under the Wiring Diagrams tab. Once a component is selected, it is highlighted in the wiring diagram which makes it easy to track. For some components there is more than one wiring diagram available. In such case all available wiring diagrams are listed above the currently viewed wiring diagram.

The wiring diagram content is automatically filtered based on the VIN of the current vehicle. Please note that a wiring diagram may look different depending on the configuration of the vehicle.

Navigation and general functions

The zoom slider is placed in the upper left corner of the wiring diagrams and is used for navigation. Zoom in and out by using the + and - buttons in the zoom slider. It is also possible to zoom by using the scroll wheel on your mouse. Pan by using the arrows in the zoom slider or grab and drag the wiring diagram to desired position by using the mouse.

Other general functions used when working with wiring diagrams are explained in the table below.

Functionality

Description

Mouseover

Holding the mouse over a signal increases the line width to show its path in the wiring diagram. Holding the mouse over a component increases the line width of the component and a tooltip containing the name of the component is displayed.

Access information

View more options and information by right-clicking components and signals in the wiring diagram. See the subsection below for further information.

View in expanded mode

Click the icon next in the upper right part of the panel to collapse the left-hand menu panels and view the wiring diagram in expanded mode. Click the icon to return to default mode.

Component and signal functions

Additional information and functions are accessed by right-clicking different objects such as components, wires and inline connectors in the wiring diagram. See the following two articles for additional information:

Symbol legend

In the tables below, commonly used symbols in wiring diagrams are presented.

 

Components

Symbol

Description

Explanation

Pin information

Connector name and pin number is shown inside the component symbol next to the connected wire.

Special connector terminal material indications

Special connector terminal materials are shown near the associated pin. Typically these are gold or silver but if nothing is indicated, the terminal material is always tin.

 

Internal component symbols

Symbol

Description

Explanation

Network membership

Components that are connected to data communication networks contain symbols for the networks which the component is connected to, such as CAN, Flexray and LIN.

Please note that network membership symbols are typically not shown in wiring diagrams that only contain information for a specific communication network.

Fuse

Fuses are indicated as internal symbols in components.

Relay

Relays are indicated as internal symbols in components.

Other internal symbols and circuitries

Some components also illustrate internal component circuitry and components such as switches, motors and lamps.

 

Wires

Symbol

Description

Explanation

Wire colors

The color of a wire is indicated by the abbreviation shown on the wire. All abbreviations are presented below.

BK

Black

BU

Blue

BN

Brown

GN

Green

GY

Gray

OG

Orange

PK

Pink

RD

Red

VT

Violet

WH

White

YE

Yellow

SCRN or SCREEN

Shielded

Wire cross section area

The cross section area is indicated on each wire next to the wire color. The cross section area is indicated in millimeters.

Signal type

The line color of a wire indicates the signal type of the wire. As an example, constant 12 V-feed is indicated with red line colors.

Broken wire

A dashed wire is indicating a wire that is most likely causing a problem.

Twist

Twisted wires are indicated by an “8”-symbol stretching over the wires that are twisted together.

Multicore

Multicores are cables with multiple conductors, commonly used with coaxial cables or when a wire is shielded. The shield is shown as a wire with the color shown as SCRN or SCREEN. The symbol indicates that a multicore stretches over the shield as well as the other wires which are shielded.

Twisted multicore

Twisted multicores are cables with multiple conductors that are twisted together, which are also shielded. The shield is shown as a wire with the color shown as SCRN or SCREEN. The symbol is a combination of the multicore symbol and the twist symbol.

Branching point

Branching points (also known as splices) are shown with the following symbol and associated branching point ID, which typically starts with 93/.

Reference

References are used when a wire continues on another wiring diagram.

 

Ground points

Symbol

Description

Explanation

Single connection ground point

Single connection ground points are indicated with a single ground symbol together with a ground ID such as 31/117.

Multi-connection ground

Multi-connection grounds are indicated with a ground symbol with multiple connections together with a ground ID.

Case ground

Case grounds are indicated as connected to a component, but without a ground ID.

 

Inline connectors

Symbol

Description

Explanation

Inline connector

Inline connectors are indicated together with the inline ID and the pin number of the connector.

Inline connector special terminal material indications

Special inline connector terminal materials are shown near the associated pin. Typically these are gold or silver but if nothing is indicated, the terminal material is always tin.
