It is as well Bluetooth compatible and it can be updated or upgraded. So, you will use it for many years to come. Whether you’re a mechanic, technician, motorist, or just an ordinary repair guy, this tool will prove to be of great help when you want to erase the check engine light.

Even though these three scan tools have a lot of similarities, they as well have their own differences. To begin with, the Innova 3140g is the most costly and more advanced code reader. Compared to Innova 3140 diagnostic scanner, the Innova 3140g has a large screen that clearly shows all the results of the scan. Also, the 3140g scanner is Bluetooth App compatible while the 3140 code reader is not.


With so many scan tools on offer, it is vital to know which one offers the best features and performance. You don’t want to be faced with the challenge of a car scan tool, not being able to read or erase particular codes. This can be very disgusting after spending a lot of cash to get a scan tool. The above 3 diagnostic code readers from Innova are some of the best for both professionals as well as startup technicians and mechanics. They are sturdy, lightweight, compact, reliable, accurate and very convenient to use. As long as your vehicle is 1996 or newer, there is a high chance that they will be compatible.
