With many years of car repair experience, I can say choosing the right OBD2 scanner isn’t a simple task. When I started this job, I had to try out different brands and types of OBD2 diagnostic scanners. But with time, I have come to know which brands and types of OBD2 scan tools are the best. Not every famous brand or highly-priced tool that you see out there will get the job done and identify the issue with your car. Even some scan wrong error codes, while others fail to detect the car problems when there is actually a grave issue. The main features of this Innova scan tool model are the Check Engine light, ABS, SRS, EVAP, and Freeze Frame. Read this Innova 3100 review to know why I am suggesting buying this scanner tool.

  1. The 3100e I have cannot do anything with ABS even though it says press this button to view ABS, Innova lied…

  2. My 3100j indicates that my 2001 F250 not supported, Will require a module for $10,
    I called Innova support, and he tech said that this referred to something on vehicle???
    I’d think there was something downloadable.

    Any ideas?

  3. Thanks for reply Kevin,

    FYI – The link offered does not work. (Error 404 – File or directory not found)

    The product compatibility lookups on the Innova site clearly indicates that my 3100j should read codes for 2001 F250
    Checked by VIN and year/make/model is 7.3 diesel indicates should all be good, but will not read. The 3100j recognizes the vehicle but will not read codes. Codes read with POS Harbour Freight reader as well as a superchips diagnostic tool.
    Reads 2000 Lexus and 2004 4Runner, but not the truck, where I really need it.

  4. I have a innova 3100 that has not been updated since it was new. Is there a software up date for it and if so please tell me what it is and how to do it please

    1. Unfortunately, not that I can find. I’m in a very similar situation. I have an older scanner that has old firmware on it and despite hours of searching online, multiple calls to Innova tech ‘support’, and numerous attempts at countless downloads and different software downloads, I have come to the conclusion that although updating the firmware should be a ridiculously simple task, as it is with nearly all electronic devices ever manufactured, Innova has been kind enough to make it absolutely impossible to update the firmware on a device. Instead, the firmware seems to be the ‘secret sauce’ that differentiates one scanner from another. It’s all about what features are enabled in different versions of the software, not the capabilities of the actual piece of hardware. …so, NO, I have yet to find any way to update that piece of hardware that functions well, just has old firmware on it. …but you’ll find yourself quickly hearing the response of “just buy a new scanner with all the new ‘features'”. …no thanks, I’ll take my business elsewhere. Am I a little bitter after spending hours trying to perform a simple task of updating firmware? ..yes, VERY much so.
