Hey, My name is Henry L. Wilburn. I am a professional Automotive Mechanic. I am working in this field from last 15 years. So, I have vast experience about car problems. A scan tool can help to identify car problems without a mechanics help. But, you should select 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 of 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, then feel free to contact me with your question.
