In some studies on newspapers there is quoted a revolution in vehicle technology. This might be right, but for road worthiness enforcement measures we have more to look for an evolution which takes into consideration new technology on the one side and the well experienced measures on the other. The vehicle lifecycle is around 12 years. So the introduction of new technology into the whole vehicle fleet will take time. The selected measures for pti in general and electronically controlled systems in special should cover new technology as well as the to days technology. The proposed test pyramid shows a solution in this understanding. The phase in time for such a procedure has to be adapted to the existing fleet at the different European MS and also to the most common systems in field. The level of necessary costs for investments is very low compared with other expenses. The bigger part of costs will be found by education and database management for supporting the right and needed information. There is no doubt, we have a lack of clear and reliable evaluations and need more experience in dealing with integrated systems in vehicles. But without starting up in such an integrated approach never the needed data and procedures will be available. In parallel to the introduction of inspection of electronically controlled systems additional studies could work on special topics in this field.
