Schematics
The schematics divide the entire vehicle electrical system into individual circuits. Interacting
electrical components are shown on one common schematic.
Switches and other components are represented in such a way that their general layout and
function are self–explicit. They are arranged on the sheet such that the current path can be
followed from positive (top) to negative (bottom).
Important: The components and wires are not drawn to scale. For instance, a lead with a length
of over 1m can be shown as a lead that is only a few cm long. To ensure clear arrangement , all
connectors, lines branches and connected components from the fuses to the component and
from the component to ground connection are not shown within the individual cells. If required,
reference can be made to cells 0670.3 Fuse Details and 0670.4 Ground Distribution where all
lines are illustrated with all plug connections, line branches and connected components.
All circuit symbols used are listed and explained in cell 0140.0 Symbols.
In cell 7000.0 Component Location Chart all important connectors, ground points and
components are listed in tabular form. It provides a precise description of the component
locations in the vehicle.
In cell 7100.0 Component Location Views the location of connectors and components which
are difficult to locate are shown in line arts or illustrations. In cell 8000.0 Splice Location Views
all splices are listed in numerical order and illustrations are provided to assist in locating splices
on larger harnesses. In cell 8500.0 Connector Views diagrams of connectors with more than 2
pins are illustrated.
Included in this ETM are foldout block diagrams. These are overviews of the entire system (EGS,
ABS, AC, etc.) which helps understand the relationships between various components and
control unit of the system being diagnosed.

Example
General conventions can be explained based on the following schematic example.

INTRODUCTION











General Conventions
1. Switches and relays are always shown in rest position (e.g. K11).
2. A component shown in a dashed frame signifies that the component is
illustrated only in part (e.g. P90 and P91).
3. A component shown in a completely drawn frame signifies that the
component is illustrated in full (e.g. K11).
4. The dashed line between pin 8 and pin 6 of connector X293 indicates
that both pins belong to connector X293.
5. The dashed line from fuse F1 to pin 8 of connector X293 shows the
positive supply of relay K11. If required, refer to cell 0670.3 Fuse Details at
fuse F1 for the complete line progressing with plug connections, line
branches, wire colors and cross sections.6. The dashed line with an arrow at splice X452 indicates that several wires
lead to splice X452. All lines leading to the connection are illustrated in
cell 6100.0 Central Body Electronics (ZKE). An interrupted line with an
arrow indicates that only this one wire leads to another circuit.
7. The dashed line from pin 4 of connector X293 to ground X493 shows the
ground supply for relay K11. If required, refer to cell 0670.4 Ground
Distribution at ground X493 for the complete line progression with all plug
connections, line branches, wire colors, and cross sections.
8. The interrupted line from splice X452 with an A in the open arrow is
continued on page 6160.0–02.
Termination of wire 4 VI/SW from splice X452 with a wavy line indicates that
the wire is continued on the opposite page.
