In case of problems with the electrical system or mechanical parts, it is important to investigate which part is defective. It is also essential to find out the cause of the problem. Take, for example, a turbo that turns out to be defective. What caused the problem? Was it a lubrication problem?
If the cause of a defect is not found, the problem may return in the future. Finding the defective or malfunctioning part and tracing the cause is what we call “diagnosis”. A good diagnosis prevents unnecessary replacement of parts. Car technicians are trained in making the diagnosis. With the diagnostic skills they learn during these training courses, they can detect a deep problem with the right measuring tools. The topics that may arise in the workshop are covered in the categories: electrical diagnosis, mechanical diagnosis and air conditioning system diagnosis.
