Quick Intro

After using different scan tools and talking to different mechanics, I finally decided to create this Innova 3100 review. This model has two versions: Innova 3100 and Innova 3100j. I am going to discuss these two models. These are the best Innova scanners that you can buy at an affordable price. Innova is a leading brand in the automotive diagnostic field and offers some of the best innovative scanners.

The Innova 3100 is an affordable scan device ideal for DIYers as it can diagnose basic functions like ABS, Freeze Frame Data, Engine Coolant Temperature, CEL, Emissions Readiness, Battery, and more…

But it lacks SRS, oil reset, and live data features.
