Fuse details 0670.3

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 cm long. To ensure clear arrangement, all connectors, line 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 the 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 the 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.

Introduction

BMW

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 P94). 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 at the connector X293 indicates that both pins belong to the connector X293.

7. The dashes line from pin 4 of connector X293 to ground X493 shows the ground supply of the 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 colours and cross sections. 8. The uninterrupted line from connector X452 with an A in the open arrow is continued on Page 6160.0–02. Termination of the wire 4 VI/SW from connector X452 with a wavy line indicates that the wire is continued on the opposite page.

0110.0 01

5. The dashed line from fuse 1 to pin 8 of the connector X293 shows the positive supply of the relay K11. If required, refer to cell 0670.3 Fuse details at fuse F1 for the complete line progression with all plug connections, line branches, wire colours and cross sections.

6. The dashes line with arrow at the connector X452 indicates that several wires lead to the connector X452. All lines leading to the connection are illustrated in cell 6100.0 Central body electronics (ZKE). An uninterrupted line with arrow indicates that only this one line leads to another circuit.
