This subject summary takes into considerationthe 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.Acontrol unit digitises the course over time, height and frequency of the sensorvoltages to further process these actual values in the micro controller.
In state-of-the-art vehicle systems,onboard-diagnosis is a standard. Workshop practice shows, however, that anyinput interferences recognised by the control unit are only formulated in veryvague detail in the error storage. The reason for this is the fact that acontrol unit cannot actually recognise whether the sensor, its connection linesto the control unit or digitalisation in the control unit are defective. Thisis 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
