The number of control modules in the CAN varies depending on the level of equipment, the car model and the structure week. The description applies to the structure week 199815-200149. The structure week and the manufacture week are not necessarily the same week. The week of manufacture is the week in which the car was manufactured in the factory. The content of the car is guided by the structure week A structure week can extend over many manufacture weeks. The structure week is specified in the format YYYYWW.
For example, the structure week 199815 indicates that the structure week of the car is week 15 1998.
