Co py iThe Transporter 2004 has an extensive network of electronic control units. Functions which were controlled in the predecessor model switches and relays are controlled digitally via the drive train CAN data bus and the convenience CAN data bus systems. The formerly mechanical opening of the sliding door is now controlled electrically. There are many other functions which also represent modifications to the predecessor model.This Self-Study Programme will give you a better understanding of the innovations to the electrical system of the Transporter 2004. This will ensure that, as before, you are able to provide customer satisfaction through technical competence.es, in part or in w l purpos hole ercia , is n m m ot p o c erm or e t a itte iv r du rp o nl f e ngAG.

The network makes it possible to exchange data between the control units. Information is sent via the CAN data bus in digital form instead of via discrete cable connections. This makes it possible for other control units to access the information. The CAN data bus is split into two single systems, the drive train CAN data bus and the convenience CAN data bus. Both bus systems are connected to each other via the data bus diagnosis interface (Gateway) J533 in the dash panel insert and this allows the exchange of data.r te o iva r rp fo g nJ623A-K J285G24do c um enJ533Prote cted by c o py rig ht .

The data transfer rate is 500 kbit/s. Data is transmitted along the CAN high and CAN low lines. The drive train CAN data bus only has ready status if both data lines are intact. In case of failure of a data line, an open circuit or a short circuit, no data transfer takes place. A fault is entered into the fault memories of the participating control units. The CAN data bus lines are colour-coded orange/black for the CAN high line and orange/brown for the CAN low line. The lines are twisted together.pe rm itte dun leAG.
