LAUNCH X431 PRO3S+ Elite SmartlinkC V2 Bidirectional Scanner J2534 Protocol

Alright, buckle up because we're diving deep into the Launch X431 Pro3S+ Elite! This isn't just your run-of-the-mill code reader; it's a serious piece of diagnostic kit that's a game-changer for professional mechanics and hardcore DIY enthusiasts alike. What makes this scan tool stand out in a sea of similar devices? Well, for starters, it packs professional-level diagnostic capabilities typically found in high-end garage equipment. We're talking about comprehensive system diagnosis, covering everything from your transmission and ABS module to airbags and all those other complex modules lurking in your car. And the vehicle coverage? It spans a massive range of domestic, Asian, and European makes, plus brands you've probably never even heard of! But hold on, it's not just about reading codes. This tool goes way beyond that with bidirectional controls. Imagine being able to send commands directly to your car to test components. Want to see if your coolant fan is working? You can command it on and off. Need to bleed your ABS system? This tool walks you through the process step-by-step. It's like having direct communication with your car's electronic brain, allowing you to tap into various control modules for testing. Now, what about vehicle compatibility? This is a big concern for many buyers. Unlike some scan tools with limited coverage, the X431 Pro3S+ Elite, being near the flagship level of Launch's offerings, boasts extensive vehicle support. You're likely covered now or will be in the future, thanks to consistent software updates that add new modules, features, and vehicle coverage. Let's take a closer look at some key features. Inside the box, you'll find the scan tool itself, the VCI (Vehicle Communication Interface), a power cord, and a nice protective case. Interestingly, it also includes an Ethernet cable for a more stable wired connection, especially recommended for remote diagnosis. Speaking of which, this tool allows for remote diagnosis with other professionals or friends across the globe who also have compatible devices. The adapter box is particularly noteworthy. Not only does it contain a wide array of connectors for various makes and models, including pre-OBD2 vehicles, but the software also clearly indicates the year range supported for each manufacturer right on the selection screen. This eliminates the guesswork of whether the tool will work with your specific vehicle. The kit also includes additional power cables and hookups for those older vehicles that don't have standard OBD2 ports. Moving into the software, the intelligent diagnostics feature quickly connects to the VCI. While it doesn't automatically read the VIN, the process is straightforward, and audible cues confirm communication. You can view live data, perform system scans, and access various diagnostic functions. The system scan provides a quick overview of all systems, while the high-speed scan offers a faster but perhaps less thorough check. The smart detection feature highlights stored and pending diagnostic trouble codes (DTCs). A particularly useful feature is the CAN bus pin detection, which provides a wealth of information about your vehicle's communication networks, aiding in diagnosing communication-related issues. Diving into specific modules like the ECM (Engine Control Module) reveals a wealth of information, including module information, fault codes, live data, freeze frame data, actuation tests, and special functions. The "special functions" menu is where this tool truly shines, offering manufacturer-specific functions beyond the generic resets found in many scan tools. For example, in the body control module, you might find functions like brake pedal sensor relearn or window learned value resets, which aren't present in the main reset menu. The live data streaming capabilities are impressive. You can select specific parameters (PIDs), such as oxygen sensor readings and fuel trims, and view them in a clear, graphical format. You can even overlay previously recorded data for comparison, which is a fantastic feature for identifying intermittent issues. The graphs are interactive, allowing you to zoom, pan, and even take screenshots for reports or record-keeping. The actuation test is another powerful feature that allows you to directly control vehicle components. For instance, you can activate the windshield wipers or washer pump to diagnose issues with the motor, relay, or wiring. This direct control helps pinpoint whether the problem lies with the component itself or the control signal. In conclusion, the Launch X431 Pro3S+ Elite is a comprehensive and powerful diagnostic scan tool packed with features that cater to both professional mechanics and serious DIYers. Its extensive vehicle coverage, bidirectional controls, in-depth special functions, and user-friendly interface make it a valuable asset for anyone looking to get deep under the hood of their vehicle and tackle even the trickiest automotive problems. While it might be a significant investment, the capabilities it offers are well worth considering for those serious about vehicle diagnostics and repair.

I work at an independent repair shop, so I see a little bit of everything. I bought this because I wanted one scanner that could cover most of the cars that come through the door without spending tool-truck money. So far, it’s been great. One job I used it on was a 2018 Ford F-150 that had a rough-running problem and an intermittent misfire. The power-balance screen made it pretty obvious which cylinder was acting up. I could watch the misfire data and fuel trims at the same time, and the bidirectional tests helped me narrow things down without wasting time checking every possible part. I also used it on a 2021 Jeep Grand Cherokee that came in with several warning lights and communication codes. AutoAuth worked without much trouble, and the topology map was really helpful. It showed the whole network on one screen, so I could quickly tell which module had the main fault and which codes were probably just caused by it. After the repair, I cleared everything and ran the tests again to make sure it was fixed. The scanner is fast, the screen is a good size, and the wireless connection has been reliable for me. Live data is easy to find and graph, and it has a ton of resets, relearns, adaptations, and active tests. I’ve used it on domestic, Asian, and European vehicles and haven’t run into many coverage problems. The first round of updates took a while, and there are so many menus that it takes a little time to learn where everything is. Other than that, I don’t have much to complain about. For an independent mechanic or small shop, I think it’s a really good value. It has already saved me time on several jobs, and I would buy it again.

Okay, let’s get the main thing out of the way- this scan tool is awesome. For reference, I’m a ford senior master technician, and I have been in this field for 21 years. I got this scan tool because I’m the only one who works on non OE vehicles at my dealership, and I wanted something to provide as much coverage as possible. This tool does more than I hoped. It’s not my first Launch- I have a 4 year old x431 pro v 4.0+, a 2 year old crp91ebt and a 2 year old CReader 2.0. I like the larger screen, and decided that this year was the year to order a replacement for the 4.0+, and this scan tool was on sale. Large screen, faster processor, more ram, great coverage and compatibility, this filled all the boxes. It comes with the smart link 2.0, which plays nice with all the new networks. The package was boxed well- two hard cases in boxes, inside a box, inside another box. Nothings going to damage these during shipping. Opening the boxes reveals a multitude of adapters, and the scan tool/ethernet cable/VCI and adapters. I powered the scan tool up, 99% charge. Boot time was about 15 seconds, already faster than my 4.0+. I logged in with my Launch account, and checked for updates. 85 updates available, not surprising. It took the better part of an hour to get them downloaded, and then I set out to test the scan tool. While I am a ford tech, as stated I work on everything, and the first test vehicle was a 2022 ram. I got the serial number and registered it with my AutoAuth account, and connected the scan tool. Everything went smoothly, and after logging to AutoAuth I had access to the secure gateway module and was on my way. Now, something I want to mention here- this scan tool is SIGNIFICANTLY faster at pulling dtcs and detecting modules than any of my other tools. I posed a video, it’s literally seconds to detect every module and pull dtcs. Instantly fast, faster than my other Launch scanners, my Actron or Autel units, and a hell of a lot faster than IDS and FDRS. The tool is also beefy- not heavy and bulky, but the case itself in feels strong, and it should protect the scan tool very well. I’m really happy it has this case, as opposed to my old 4.0+ which didn’t feel this sturdy. Getting in to checking data, the same layout is used, which is good because it’s simple to use and it’s well laid out. Data logging is easy, and you can display a good amount of PIDs, as shown. Checking a Chevrolet, the results were the same- more than satisfactory. Tons of data, ease of use for retrieving and clearing dtcs, everything well laid out. Finally I took it to a super duty, my bread and butter. Pulling mass air flow sensor data was quick, as was going back and retrieving cylinder mass PIDs. Power balance is fast and crisp, and updates the graph data quickly. This scan tool has 99% of the reset functions that IDS and FDRS have, and using the bidirectional controls, I could test the egr valve and coolant bypass valve. After the repair, I used the scan tool to run a manual regeneration, which completed flawlessly. Overall this is an amazing scan tool. It works perfectly with my Launch TPMS wand and Launch battery tester, and this unit has the option for an oscilloscope as well. I will update if there are any issues, but I don’t foresee that being a concern. Overall, this is a professional scan tool that will cover most of what’s on the road. It’s fast, it’s powerful, and it should last for years.

This scanner does it all! Its bi directional, J2534 compliant, has a large touchscreen with stand, and accepts many accessories such as lab scope, horoscope, battery tester, etc. These launch scanners are also very good with European makes as well. I used to have a Snap On Triton D10 that I used until I found out about these. You get all of the same power for a 10th of the price, and you dont have to pay massive update fees every 6 months. What sets this specific scanner aside from other Launch models is the fact that it can program, and it will now scan the whole car much faster than previous models have in the past. I am a Launch customer for life.

Did not have much luck. Quite a weird exit button: instead of bringing you one step back, it kicks you out to a main screen. Every new start is an authentication check … having bad luck reading Mercedes data is wrong; for example, freeze frame registered a speed of 257 and a temperature of -58?! Seriously?!?!?!?! Another example, after resetting a “service A “, just got an error that service B is overdue now with over 12k.…. afraid to continue, do not cause any damage to the ECU

This tool is awesome! It really does everything. It comes with a very high quality and durable fully featured android tablet for diagnostic use. Even better is it includes an extra box with tons of OBD adapters for all sorts of vehicles. It even has adapters for older OBD1 vehicles, and will work with heavy duty 24V trucks, vans, and industrial equipment. The tablet works with the LAUNCH smartlink diagnostic interface over bluetooth. The diagnostic interface connects to your vehicle. It has a full color touch screen as well so you can view connection and vehicle status right on the interface. Since the tablet is connected over bluetooth, you can use the tablet anywhere around the vehicle which can be very useful. The smartlink interface can be connected to a computer and used as a J2534 programming interface for use with OEM diagnostic software. It can then be used to program and update vehicle computers. Super powerful feature for a full service shop that works on many types of vehicles. The X431 Android app on the tablet is amazing. It is very easy to use, and includes all diagnostic routines plus special services and many extras. It can auto detect your vehicle, and shows you a topology map of all of your vehicle modules and systems. You can then access each one for further diagnosis. The unit is also expandable with many more tools including an oscilloscope module, key programmer, immobilizer programmer, borescope camera and more. Overall you will not be disappointed, this is a do-it-all tool for the home mechanic or professional shop. Very happy with this!

UPDATE - I got it updated and It works better now. The dongle is still says unsupported mode (or something like that) but I just have to click ok for that to go away and it works fine. I hope I don't have to log in again because I have no idea where to log in or username and password to use. Initially, this scanner worked great—I registered it, and it did everything I needed. However, after an update, it started asking for a password. I logged in successfully the first time, but a few days later, it asked again, and my saved password no longer worked. No login method has worked since. I even tried the captcha, but I never received the PIN. At this point, the scanner is unusable, which is incredibly frustrating, especially since I purchased an extended warranty. I'll try a few more troubleshooting steps before considering a return, but right now, it's feeling like an expensive paperweight.

I bought this Launch X431 Pro3S+ Elite to replace my Launch X431 Pro3s+ that I bought back in 2022. The 2022 Pro3S+ is a great tool, and I had zero problems with it for over 2 years. I just bought the Pro3S+ Elite because of the expanding abilities that it can do. With the Pro3S+ Elite, one can add a 4 channel Scope to it, add a Sensor box, and HD trucks capabilities too. There are more capabilities than that so just research the tool in the description to learn about it, too many to name in this review. My older 2022 Pro3S+ cannot do these things, so this was my main priority for buying this Pro3S+ Elite. The Elite is much faster too. I expect great things from this tool. I expect no problems from it too, being the 2022 Pro3S+ gave me none. The Smartlink C box is a stand out too with it's remote diagnosis capability which I'm still learning about. This tool can do J2534 programming too so keep that in mind when determining the value of this tool. It is feature packed and future proof too with it's free 2 year updates included. You can't go wrong with this tool. I could go on and on about it, but I won't. Just do your own research, assess your needs, and buy this confidently, knowing you made the best decision for this price point. Much better value than the big name tool truck guys. Research and find the same conclusion.

So far it has been perfect. We have peterbilt, freightliner & Dodge in or fleet & it works perfect for all of them it's definitely a money & time saver. Should have bought one sooner.

One of the best scanner that used so far how long lots of brand, lots of functions, by directional scanner, easy to use

The best scan tool for this money

According to price it’s totally money waste In description they mention lots of things but too many functions not working
