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 which
is only a few em long. To enhance the clarity
of the schematics, all connectors and splices between fuses and components as well as be-
tween grounds and components have been omitted. If this information should be required,
it
may be referenced in cells 0670.3 Fuse Details and 0670.4 Ground Distribution.
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 loca-
tions In the vehicle.
In cell 7100.0 Component Location VIews the locations of the connectors and compo-
nents which are difficult to locate are shown in photographs. In cell8500.0 ConnectorVIews
diagrams of all connectors with more than three 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 con-
trol unit
of the system being diagnosed.
Example
General conventions can be explained based on the following schematic example.

General Conventions
1. Switches and relays are always shown in rest position (e.g. K 11 ).
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 compo-
nent 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 1
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 col-
ors 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 supplyfor relay K
11 . If required, refer to cell 0670.4 Ground Distribu-
tion at ground X493 for the complete line progression with all plug connec-
tions, line branches, wire colors and cross sections.
8. The interrupted line from splice X452 with an A
in the open arrow is contin-
ued 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.
