How to choose the right OBD-II scan tool for your car?

Figure out what functions do you need from the tool.
Do you just need to read the trouble codes or erase the codes? Do you want to close the check engine light when it is on? Or do you want to access to more advanced data besides the engine data? So choose the tool that best fits your need.

Set your budget for the tool.
There are many kinds of OBD-II scan tool averaging 20$ to 200$ on the market. Generally the more functions the tool has, the more expensive the price is. 

Make sure your car model is supported by the tool.
Find out the manufacture year and model of your car and make sure it is OBD-II/EOBD compliant. Then choose one that is compatible with your car. A normal OBD-II scan tool should support cars that are OBD-II/EOBD compliant. 

Confirm this before you buy from the seller.
