1. The wirting diagramm of a VW Beetle from the sixties of the last century fits on a .

2. To accommodate today's concentrated electronics, the term is used.

3. Telematics is mainly concerned with digital electronics, which got into the vehicle via .

4. It can be up to 10 km long, the .

5. The helps to reduce them.

6. If the lighting system of a motor vehicle is controlled via CAN bus, for the installation of a trailer coupling, an additional is required.

7. Such lighting systems would have the advantage, among other things, that already at the start of the journey in the morning and not only at nightfall a possible is noticed.

8. Omitted in a CAN bus controlled lighting system is the for the direction indicator.

9. How can such a CAN bus possibly help to avoid fuses? A control current is only switched on for such a short time (ms) that a considerable cannot happen.

10 Basically only one cable is important for a simple CAN bus. Via this, so-called are sent.

11. Of course this is only possible between two .

12. Usually a lot more of them are involved in such a bus, but none of them has a function.

13. Data cables do not transmit high currents, so they can manage this with less than a half square .

14. The DC voltages are, as is often the case in digital electronics, up to Volt (TTL voltage).

15. The best instrument to analyse CAN bus problems is an .

16. The name 'bus' comes from the fact that, as with a bus a message is delivered and/or received at each stop.

17. The 'stops' are also called bus-.

18. Of course there are messages of special .

19. That could be the ABS signal of the system.

20. The CAN bus is designed so that such signals especially are transported.
