A control unit digitises the course over time, height and frequency of the sensor voltages to further process these actual values in the micro controller. This subject summary takes into consideration the fact that all electronic vehicles systems record the actual value of apartial system under consideration with sensors. Sensors convert non-electricalphysical values like positions of actuators, temperatures, pressure,brightness, etc. to electrical voltage that is decrypted by a control device.
This is where the service workshop comes in, where the sensor-side is diagnosed bymeasuring technology. The present lab system provides real measured values forthe intact and defective system by the diversity of practice-related sensors. In state-of-the-art vehicle systems,onboard-diagnosis is a standard. The reason for this is the fact that acontrol unit cannot actually recognise whether the sensor, its connection lines to the control unit or digitalisation in the control unit are defective. Workshop practice shows, however, that anyinput interferences recognised by the control unit are only formulated in veryvague detail in the error storage.

Diagnosis of electrical systems is essential atthe car service workshop. The basis of diagnosis is the competence ofrecognising the electrical basic principles applied in the diverse, networkedvehicle systems, how they interact in a partial system and how to verify thisin measurements. The system comprises all required components; it is compact, can be used at once,and permits free wiring. The focus of the pedagogically valuable coursedocuments is on car diagnosis.
In the end these initially seemingly chaotic partial and overall systems can bereduced to simple circuits where the basic principles apply. When using vehicle lamps in the basiccircuits and collecting experience with non-linear behaviour, the learners maketheir first step into the professional world. The unique course comprises comprehensive documentation and extensive worksheets for teachers and students.The solutions book contains additional further explanations and solution charts. It can be assumedthat the trainees targeted here are not dealing with electrical engineering forthe first time. Still, the first tasks may commence with basic circuits already known to confirm what was taught before.
