This is a mechanic who does not diagnose problems, but simply exchanges whatever he is told. Additionally, in the past, mechanics could obtain employment through trial and error, which is a general problem-solving method. Because the process of this method took too long, people had to be trained to diagnose the source of the problem. To acquire this skill, a person must have the right experience instead of just learning from their mistakes. A technician must be able to see and understand all parts of a vehicle as a whole to manipulate the functions of an automobile. That's why it's important for technicians to understand how to operate systems throughout the vehicle. Since each part plays a major role in the operation of the automobile, most technicians will choose to specialize in a specific skill. Technicians must understand an automobile's system to use their reasoning skills to diagnose problems within the car. Understanding each function of the automobile shows the difference between a mechanic and a technician. This is why technicians occupy higher paying positions than the average mechanic (Nature of the position).
