I am a professional Automotive Mechanic. I am working in this field from last 15 years. So, I have vast experience with car problems. A scan tool can help to identify car problems without mechanics help. But, you should select a quality scan tool. I have used lots of obd2 scanners in my life. 

Thus, It is not hard for me to suggest quality scan tools. I have used more than 100 scanners. From my experience, I will share each tool advantages and disadvantages. I will also share the main features of those scanners. 

So, it will be easy for you to select a good quality scanner. Moreover, I have done a list of scan tools for Beginners, Pro DIYers, Professionals or Mechanics. If you didn't find your query on this website(https://bestobd2scanners.com), then feel free to contact me with your question.
