During the last decades an increasing trend to the use of electronically controlled systems in vehicles can be observed. Especially in the area of the emission regulation and reduction, which was intensified by the legislation, we owe our success to the first electronic engine management and monitoring systems. Also in other areas, e.g. security, comfort or infotainment this trend can clearly be observed. Additionally, a lower number of accidents and road casualties, although the traffic volume in this period constantly increased, has been achieved by the introduction of different vehicle safety systems (discussed in WP320). Beside the mentioned advantages, these new systems also carry certain disadvantages, e.g. the complexity of the systems and thus a certain fault liability. In order to make the complexity of the systems controllable and to ensure their functionality, different diagnostic mechanisms are required, which have to be considered already in the development and used over all phases of the vehicle life cycle. As a goal of this work package, diagnostic mechanisms for different phases of the vehicle life cycle will be documented and their contribution to the road safety shall be evaluated. In addition, today's and future developments in the vehicle diagnostics in order to improve both the system integrity and the development quality, are to be dealt with. In particular there are numerous standardisations and new technologies to be considered. Furthermore, different applications of telematics in the vehicle are to be presented and to be evaluated regarding their use for the off board diagnostics and their role for the road worthiness enforcement.
