Electrical engineering challenges are clearly the main focus. The teaching of essential basic knowledge is followed by practical exercises to control the knowledge transfer and to consolidate the knowledge. The focus is always on a systematic approach to analysis. Basic knowledge of electrical, hydraulic, pneumatic and BUS systems is not a prerequisite, but knowledge of hydraulics and / or pneumatics is helpful. In the beginning of the fault analysis, the visual and, if necessary, also acoustic observation is carried out, followed by measurement methods for fault containment. Last but not least, the possibilities of visualization are also used. The focus is on the acquisition of basic knowledge of electrical engineering (components, measurement technology), analytical and structured approach to troubleshooting (analysis instead of component replacement), holistic view of the entire system / vehicle as a unit (electrical engineering / sensor technology – actuator technology).
