Designations on electric schemes

1 - Relay No. Indicates the location of the relay on the relay board.

2 - designation of the relay / control device on the relay board

The legend indicates the name of the element.

3 - designation of the fuse

For example, fuse No. 19 (10 A) on the fuse holder.

4 - the symbol for the plug connection on the relay board

For example, contact 3 / 49a:

3 pin 3 in place 12 of the relay board

49a terminal 49a on the relay / control unit.

5 - the symbol for the plug connection on the relay board

For example, A13 - multi-pin connector A, pin 13.

6 - wire cross-section, mm2

7 - wire color

8 - extruded number on a white wire

It facilitates identification with a large number of white wires of one bundle.

9 - designation of the connection terminal

With the terminal designation, which can be found on the original part.

10 - measuring point of the fault finding algorithm

The number in the black circle indicates a pattern or an algorithm for troubleshooting the AUDI.

11 - designation of the hazard switch

12 - element designation

The legend indicates the name of the element.

13 - indication of continuation of the wire

The number in the square indicates the coordinate of the continuation.

14 - internal communication (thin line)

This connection does not exist as a wire.

15 - indication of the continuation of the internal connection

The letter indicates where the connection continues in the nearest circuit element.

16 - mass point designation

The legend indicates the position of the mass point in the car.

17 - relay board with fuse holder

18 - cable

19 - coordinate of the chain
