Konnwei KW680 OBD 2 OBD II CAN Diagnostic Scanner Car Engine Fault Code Reader-Scan Tool
The KW680 OBD2 scan tool is a good low-cost unit that will read and clear engine codes.
It has a nice user friendly menu that makes it easy to use.
It is a good fit for home users or the part-time mechanic that needs a code reader.
Once a code is found using Google is the best way to find how to fix the problem or at least what it will cost.
I am still testing the unit so far with good results and will update if anything changes.
As always be sure to read the reviews on Amazon, forums, or elsewhere to be sure a unit is a good fit for you.
