Glossary of electrical components: Introduction

This glossary contains electrical components from the circuit diagrams found in diagnosis, together with the respective abbreviated designations for the components.

Abbreviated designations are the descriptions of the components found in the circuit diagrams. Example: "A210" for the control unit "door module, rear passenger side".

This glossary contains approx. 2,000 abbreviated designations.

This glossary contains the following information:

• Abbreviated designation (alphanumerically sorted)
• Component
• Information: Reference to a component description in an SI Technology bulletin (SBT).

  If there is not a more detailed description of the component available, a short description of the component will be given in column headed "Information".

• KoGr.: Main group for the component

  Each abbreviated designation with component is assigned to a main group.

  An overview of the main groups can be found in the SI Technology bulletin (SBT) "Abbreviations".

• Model series: Overview of model series in whose circuit diagrams the abbreviated designation is found.

This glossary contains the abbreviated designations for the following circuit diagrams:

• Circuit diagram-DVD "BMW V 5.0", status 03/2005 (WDS: Wiring Diagram System):

  This DVD contains the circuit diagrams needed for diagnosis on BMW vehicles.

• Circuit diagram-DVD "MINI V 3.0", status 03/2005 (WDS: Wiring Diagram System):

  This DVD contains the circuit diagrams needed for diagnosis on MINI vehicles.

This glossary contains the abbreviated designations used in both these DVDs. Abbreviated designations that are only  found in the overviews "Component- and signal information" are not  contained in this glossary.

For technical reasons associated with the system, some model series are listed together, as follows:

• E60 and E61
• E63 and E64
• E65 and E66
• E83 and E85
• E87 and E90
• R50, R52 and R53

For this reason, it is possible that an abbreviated designation is assigned to a model series even though the component concerned is not found in that model series.
