The blue colored code reader is very easy to use with its simple interface. The display helps to show values and results. Also, it displays 25 vital pieces of information at a time.

So, you will have an easier time reading and interpreting outcomes. Apart from reading and erasing check engine light, this diagnostic scan tool can as well show freeze frame data, diagnose & erase anti-lock brake system, indicate if your car is ready for an emissions test.

A bit larger and powerful than the Innova 3030g, the Innova 3030h is an improved version of the 3030g code reader. But it differs from it as it has a larger screen and more functions. The Innova 3030h diagnostic scan tool is built with a durable plastic casing that is able to defy toughness. It is a wonderful tool for DIYers, beginners, and for professional technicians.

Differences Between the Innova 3030, 3030h, 3030g Diagnostic Scanners

First and foremost, the Innova 3030g and Innova 3030h are improvements from the Innova 3030. Innova 3030 has a black and white display, while the Innova 3030g and Innova 3030h have colored displays. Their display is also bigger than that of the Innova 3030 code reader.

Another difference is that 3030h has more features than the other two models. For instance, it has a DTC severity for OBD 2 vehicles. This makes it be superior to the other two code readers and as well slightly expensive. Innova 3030 is the cheapest, followed by Innova 3030g.


If your work is just finding out why the check engine light is on or to see if your car will pass the smog test, I would suggest that you go for the Innova 3030 scan tool. But if you want to perform some extra functions, then acquire the Innova 3030h code reader. I hope you have gotten a clear idea after reading this Innova 3030 review article.
