Looking at what makes up a MDI-2 scan tool system. I've been using an OTC Genisys 5 EVO scan tool for 5 years, plus I have a Tech 2. The Genisys is a decent scan/test tool for a broad range of cars. The Tech-2 does more than the Genisys for GM cars.

The GM MDI system started to appear in some GM cars around 2009 and was pretty much in all their cars by 2014. I have a couple cars that are GM MDI so I'm thinking about an MDI setup.

What I've found so far leaves me with some questions. My questions are: 1) What's the hardware setup?

From what I read, it's an MDI-2 module and a Windows-based PC. 2) Is a subscription needed to just download the PC application software and updates to the PC? Same for MDI-2 firmware updates? Are these separate subscriptions for just the software or the same subscription service that makes calibration files available? 3) Does this setup have some functionality when operating stand-alone like the Tech2, or does it always need to be connected to TIS2WEB or some other subscribed service? From what I've read, you need to have a subscription for the calibration files, but it is not clear to me that a MDI system will operate stand-alone and what the scope of those stand-alone functions are.

From what I've read so far, I believe that the system will operate stand-alone for scanning, live data streams, and two-way function testing without a subscription or connection to a GM-provided service, but want to verify.

4) Subscriptions. I see there are short-term, relatively low-cost subscriptions available for calibration files. Anybody used those? 5) Also would like to verify the MDI system is 'backwards' compatible with the cars the Tech 2 now covers, perhaps making the Tech 2 unnecessary. Appreciate any comments from those who have experience with MDI.

Here's an informative link about the scan tools, including discussion of the Tech 2, MDI and current GDS 2. It looks like the trend is toward subscription services and frequent payment for updates. I'm trying to determine if there is any OBD scanner with full dealer diagnostic capabilities (without bilateral reflash or programming capability) that works on 2014 and later GM cars and does not require a subscription. Drew Technologies' products (CarDAQ and Mongoose) are alternatives to the GM products but still require communication with GM software, e.g., Tech2Win for Diagnostics and TIS2Web software, both of which are available by subscription.

I too would also appreciate information on the use of the most currently available diagnostic scan tools and how dependently or independently they can operate. So far I've concluded that the minimum subscription cost is to obtain a three-day usage license for GDS 2 diagnostics at $55 or $57- see this link: Are there any Techs on here, maybe from independent shops, with more insight for us? Ttt As per the above, I'm still interested in acquiring a complete turn-key MDI scan tool system to be used on Chevrolets up through and including 2015. I've been seeing some Chinese clone systems here and there (including the PC), some with subscriptions out to a year, and some with lifetime subscriptions. Appreciate any comments and information from those who have ventured into their own MDI systems. Not interested in flashing any modules, just the diagnostic and two-way test and maintenance routines. Yes, the MDI 2 is backwards compatible, and still uses Tech2Win for the older cars like the C5 and C6.

You can get it bundled with a wireless adapter so it does not have to be physically attached, but I never use it like that. The device itself is made by Bosch, looks pretty much like the original MDI, I have one of those too.
