When encountering problems with the electrical system or mechanical components, it is important to determine which component is faulty. It is also essential to identify the root cause of the problem. Take, for example, a turbo that turns out to be defective. What caused the issue? Was it a lubrication problem?
If the root cause of a defect is not found, the issue might reoccur in the future. Identifying the faulty or malfunctioning component and tracing the cause is what we call “diagnosing.” A proper diagnosis prevents unnecessary replacement of parts. Automotive technicians are trained in diagnosing. With the diagnostic skills they acquire during these trainings, they can use the right measuring equipment to locate an underlying issue. The topics that may arise in the workshop are covered in the categories: electrical diagnosis, mechanical diagnosis, and air conditioning system diagnosis.
