Snap-On Modis Ultra Scanner Scan Tool EEMS328 with Accessories
Snap-On Modis Ultra EEMS328 is more than just a reinvention of the original MODIS. It combines speed, superb diagnostics, a sophisticated look, lab scope and a ton of helpful resources in one easy-to-use device.

The Modis Ultra EEMS328 scan tool has everything you need in an OBD scanner. The 8-inch touchscreen display makes it easier to navigate. If you combine that with its sophisticated construction and super-fast diagnostics, you’ll realize you have a real life-saver.

It doesn’t just tell you what’s wrong with your vehicle; it does so in a time-saving fashion. These are some outstanding features of this model:


The Snap-On Modis Ultra checks and clears codes for all OBD2 vehicles. The scanner covers over 40 vehicle models.

OBD2 cars are those manufactured from 1996 onwards. So your car is a 1996 or newer model, you can definitely use this tool to check for and repair mechanical problems.

The EEMS328 is also compatible with selected OBD1 models (vehicles manufactured before 1996). They include 1980-newer models made in the US, 1983-newer models made in Asia, and some 1992-newer models made in Europe.

As for OBD2, the Snap-On Modis Ultra connects directly to the car’s system using a single, keyless cable. It can read your car’s system even without you having to change keys. That should save you some precious connection time.


The Snap-On Modis Ultra scanner reads and clears codes for all available modules in the vehicle.

That includes traditional systems like transmission, engine, steering, body, airbag, and suspension. It also covers newer technologies like park assist, the steering sensor, hybrid power, TPMS, and so much more.

The best thing about this scanner is its unique “cause and effect” feature. It not only reads codes but also tells you the root cause of any detected problem.

The Snap-On Modis Ultra EEMS328 also runs automated functional tests like tire calibration, cylinder contribution, brake bleed, caliper rewind, steering angle check, and service reset, among others. Basically, it pinpoints and reports every single problem.


First of all, the Snap-On Modis Ultra scanner is a one-touch access device. It means you get entry into the car’s systems with just one touch. That makes it much better than most OBD tools, which require tedious navigation before access.

Even better, the device only takes 5 seconds to boot up and 30 seconds to start displaying diagnostic results. You can’t get a scanner that can beat that speed!

Still, on the subject of speed, the Modis Ultra is fitted with a lithium-ion battery to save you some time. It switches from the car’s power to battery automatically. There’s no need to stop your scan to recharge the scanner.


The big, 8-inch touch screen keypad fitted on the Snap-On Modis Ultra is a welcome feature. With a resolution of 800 x 480, it gives the scanner a sleek, ultra-modern appearance. It allows you to navigate and operate the device with ease.

As far as data storage goes, the scanner has a removable micro SD where codes, diagnostic results, lab scope data, previous vehicle ID, 2000-frame scanner videos, and images are stored.

You can download all that information to a PC by using a USB cable. Or you can use the ShopStream Connect app (from Snap-On) to do the same.


Originally, Snap-On released Modis Ultra Scanner Tool EEMS328 with software version 15.4. Today it runs on version 17.4, an upgrade of the original.

The current software also comes with SureTrack. This feature examines the vehicle and provides records of verified replaced parts.


The Snap-On Modis Ultra scanner comes as a full kit that includes a power adapter, cables, and original box. Here’s a more specific list of items in the package:

  • The scanning device
  • 4 Snap-On adapters
  • 2 Snap-On secondary cables (one green and the other yellow)
  • 9 Snap-On “S” keys
  • 9 alligator clips
  • 2 test pins
  • AC adapter/charger
  • Micro SD card (4GB)
  • USB cable
  • User manual
  • Getting started pack

Other Pros

  • Size: the Snap-On Modis Ultra measures 12.5 x 6.5 x 2 inches and weighs 3.2 pounds.
  • Wi-Fi: this feature helps you get diagnostic answers and tips in a matter of seconds.

Snap-On Modis Ultra Cons

Perhaps the biggest drawback of the Snap-On Modis Ultra is its price. You will have to spend lots of money to get one. That’s quite expensive for someone who is not a professional mechanic.

While it works perfectly with OBD2 cars, it is not compatible will all OBD1 vehicles, especially non-US makes.

The interface is amazing, but the 8-inch screen makes the whole device rather larger than most other OBD scanners. But it’s still very portable and easy to store in a car’s compartment.

Who Is It For?

Overall, the Snap-On Modis Ultra is not complicated but can handle the hardest of diagnostic tasks. It is quite sleek and sophisticated compared to other scanner tools. You don’t need a lot of expert knowledge to find your way around it.

At the very least, it will help you figure out the problem every time the Check Engine Light comes on. You can also use it to improve your car’s performance. That’s virtually everything you need in a scanner.

The Bottom Line

The Snap-On Modis Ultra EEMS328 is specifically designed to help professional mechanics handle diagnostic tasks easily. Basically, you can use it to diagnose your car’s problems even before a professional mechanic steps in to help.
