The media could not be loaded. As a designated diagnostician/mechanic amongst my family and friend group, I have been looking for a full-featured scan tool capable of reading codes from all vehicle systems and doing bidirectional control tests of key components. This tool has definitely filled that need and has some additional convenient features as well.The wireless VCI is very nice, as I can move to the engine compartment and around the vehicle where I need to be and set up to observe results of bidirectional controls. Included with the VCI is the OBD2 cable, a USB cable to connect directly from the VCI to the scan tool (without Bluetooth), and a few options to connect 12v power the VCI if a different connector/adapter is being used for diagnostics. Because I will be using mostly the OBD2 cable, I now leave the DB9 to OBD2 cable on the VCI all the time and store it in the "lid" of the case. This is less secure than removing the OBD2 cable and storing the VCI in the foam cutout, but because I don't travel much with the tool it works for me.I have included a couple pictures of the paper showing the non-16 pin adapters and their applications. Each of these adapters has the DB9 connector on it so that it can be connected to the VCI. I will not have much need for these adapters, but it's good to have them in case I come across a vehicle that does not use OBD2 for diagnostics.On to actually using the tool. On newer vehicles, the device decodes the VIN and you only have to select the area and specific options before accessing the diagnosis menu. If the VIN can not be decoded, you will have to input vehicle and powertrain information manually to access all features. Once the vehicle information is populated, the default system selection screen shows ECU topography. If you are not familiar with all of the ECU abbreviations on a vehicle, you can switch to a system list to see and select the ECU you need to diagnose. One of my favorite features will scan the whole vehicle to detect what ECUs are responding, and will also scan each ECU for DTCs. A system will show as green if it is responding with no DTCs, red if the ECU responded with DTCs, and grey if the system is not responding. The system can also be selected to show which DTCs are present without entering advanced diagnostics, which is helpful in tracking down what DTCs may be related to other systems and choosing the best starting point.I have gotten a chance to explore some of the service functions and bidirectional controls on a few vehicles, and so far I am impressed with what is available. I have used the Subaru rear brake maintenance mode, and performed active tests on GM body ECUs, including mirror and window activation, and horn relay commands. Equally impressive is access to Cummins ECM functions such as cylinder balance tests and injector tests. I have included some pictures of available tests on Dodge with the Cummins engine, and of some of the advanced OBD mode selections.In conclusion, despite a few menu options that are not necessarily intuitive to understand, this tool is not one I am likely to outgrow any time soon, and will definitely help with getting precise component diagnosis on all the makes and models I work on.

As a mechanic who’s into US vehicles, I was really happy to see this scanner give me exactly the support I needed. It handled ABS light issues flawlessly—pinpointing a bad front-right sensor on my Ford F-150—and did the same on other makes. For Honda TPS testing, the PRO3 APEX beat every other tool I’ve tried (yes, even my Snap-on), delivering spot-on, reliable results that reinforce its reputation as a top-tier diagnostic tool.No single scanner does absolutely everything, but the PRO3 APEX comes surprisingly close. In my mid-sized shop I usually juggle multiple tools, but this one’s cost-to-satisfaction ratio is unbeatable. It packs a real punch, and for what it offers, it’s worth every penny.This latest LAUNCH addition is more than adequate for a shop like mine—whether you’re working on an F-150, Silverado, or Ram, it’s an investment that pays off in performance.

Seriously impressed by how good this model is—especially the display. Compared to my X431 V+, the difference is night and day. The PRO3 APEX’s touch response is lightning-fast, and the thicker glass means I don’t have to panic if it takes a tumble.One big reason I picked this model is that it supports the CAN FD protocol. Since more new cars are using it, having a tool that works with it is a must. This way, I’m set for whatever car I might work on down the road — and I didn’t want to buy something that’d be outdated in a couple of years.

Comes in a nice hard case box. Feels well made. There’s a slight learning curve if new to launch. But after getting familiar it’s fairly easy to use. Looking foward to using more of what the scanner has to offer.

I thought it would be bigger but seems nice.. let's see what's it capable of.

This thing is a beast of a scanner! Connects easily and is a bargain for everything you get!

This scan tool does 95 percent of what a factor scan tool can do and even more. Working on a Toyota I was able to see all my ROB data in one place and clear in one place. Where with the factory scan tool you have to go into each ECU one by one. It also runs automatic secondary air injection test and evap test. I love the topology as well too. 10/10 would buy again!

The media could not be loaded. I purchased this tool recently and was very impressed with its coverage and functionality. I used it on my personal 2013 Transit Connect and it controlled the High speed fan without issues. I also like that you can have it in landscape and portrait mode by simply turning the tool in the orientation you like. So far I am loving it and plan to put it in rotation with my other scan tools.
