Launch Diagnostic Scanner: Exceptional Value and Comprehensive CoverageAfter several months of daily use across a variety of cars and vans, this diagnostic unit has proven to be an outstanding investment and fantastic value for money.Functionality and Vehicle CoverageThe scanner offers comprehensive diagnostic coverage, seamlessly handling everything from basic code reads to more advanced functions like viewing live data streams and graphical displays. Crucially, it has successfully connected to and diagnosed every vehicle I have worked on to date. Its capabilities cover all aspects of modern diagnostics, with the exception of specialized oscilloscope functions.Performance and SpeedThe unit features a quick start-up time and is exceptionally fast when reading data from modern vehicle ECUs. While I've noted a slight slowness on older vehicles, this is generally consistent with the slower communication speeds of older ECUs and is not a fault of the tool itself. Regular software updates are provided, ensuring the tool remains current with new vehicles and diagnostic protocols.Value and Professional ComparisonFor a professional environment, this scanner offers a significant financial advantage. I find myself regularly preferring this unit over my Snap-on scanner, primarily due to its considerably lower purchase price and the much more affordable ongoing update fees.Connectivity NoteIt is worth noting that the scanner occasionally requires an internet connection when initially connecting to some vehicles or when performing software updates. This is easily managed by using a mobile hotspot or available Wi-Fi and has not been an operational obstacle.VerdictThis Launch scanner is a must-have tool for any professional technician or serious DIY enthusiast. It delivers high-end functionality and reliability at a fraction of the cost of its premium competitors.

Excellent scanner, whilst every mechanic wants a tool that does everything, I can say this will do exactly what you want.If you want to intricate stuff, then I guarantee you, you’ll not be making money!I set up my business 26 yrs ago, and we run a Launch, Autel, Topdon snap on Zeus and 2 x VCDS.I run so many, because everyone of my mechanics, has his own. Don’t be fooled with experience all singing scanner, in reality you don’t need them.

Overpriced

This does the job it’s intended to do. My son used to use these when he worked for the main dealers and the brand is fairly good regular updates or share this with my son who uses it to sort his friends and family out.Save a fortune on garage resets do the job at home but it is useful if you have been trained in this diagnosis tool

👍👍

Had a bit of trouble with the scanner , contacted launch china , where very helpful, getting it replaced, 😎

The advert says its for cars and HDIII , its only compatible with trucks, when it arrived, there was only the car software Installed, I needed it for both, although half way down in the description it says only compatible with HDIII, It also states works with 12vlt - 24vlt and at first glance looks like it has the software for both,It’s all a bit confusing, how ever the Launch diagnostic tool is spot on, great bit of kit, once i got the correctOne, Just a shame i had so much messing about to get the correct product.

Delivered in an appalling state. Badly wrapped and in an unprotected box. In particular there was no base protection in cardboard box so during the logistics it would have easily received damage, which is annoying considering the price. Could have been second hand, although to be fair, Im unsure. Didnt work and online- Launch support were absolutely useless me to try diffrrent leads from different brands,hardly professional. Amazon very helpful and professional at all times so luckily enough got my money back. Otherwise with another company, who knows! Hence why I always shop with Amazon as I feel much safer with them.

When buying and OBD scanner, it’s important to understand that the access you have to the ECU, TCU and other modules are all regulated by the vehicle manufacturer and the limitations they’ve set. In other words, if you can’t re-program the injector codes with a OBD CAN BUS scanner, it probably because of the vehicle manufacturer, not the scanner. Obviously, I’m talking higher end scanners like this LAUNCH X431 PRO3S+Smartlink HD Heavy Duty Truck Scanner versus more basic read only tools. That being said this dual heavy truck PLUS extensive car, heavy equipment scanner also includes a VCI device that can do remote assistance networking (a more experienced person can remote in) and this tool also allows connecting via a PC (typically laptop), so you can run manufacturer compliant software for all functions (extra money, as the manufacturers want a cut). This is why buying a unit with the SmartLink C V2.0 might be best. In my sample video, I’m driving up steep grades (State Rd 89A from Sedona to Flagstaff, Arizona) evaluating my DT466e using chosen (you pick what you want displayed) live data. On my 2006 bus, it offers about 25 - 30 live stream options. On newer vehicles obviously many more. I’ve just replaced all six fuel injectors, my fuel pump and other components. I the graph mode, it’s easy to compared what injection pressure the the ECU is requesting and what the high pressure oil pump is delivering. I’m also comparing the same to see if the EGR valve is doing what the ECU says. Plus, I’d replaced a new fuel pump that only managed 42psi with a Bosch that’s doing the 60 plus under load. Driving up hill was a great test. I’d had a couple codes after the repair, but this verified it was just left over air in the system. The tablet is well made, the battery was at 65% after two to three days of occasional use plus the longer live data drives of over an hour or so. The boxes, cables, display, VCI are all very nice and well made. The menu is easy to learn. I made the jump to the more expensive unit for all the features, cars, trucks, heavy trucks, heavy construction equipment all included. Highly recommend.I just want to add, someone commented on poor customer service and that this was the international version. When I ordered, I forgot to click the free gift button for the battery analyzer. So, I emailed Launch in China with my order number. Within 24 hours, they responded and shipped me the battery analyzer for free. It arrived within a week. I’ve also asked other questions with reasonable fast responses, about 12 to 24 hours. Remember, they’re asleep during the USA day. Re: Launch USA, they are just a supplier (I’m guessing third party) of Launch products. This is why the options on their website are less. Probably, do to license restrictions or Launch (China) trying not to cut their own margins. As a manufacturer myself of skid plates, made in the USA, I totally get this. Launch in my opinion, is a great company!

Im still getting used to it. But what i know is ill never pay a dealership 200 dollars for a diagnostic only for them to tell me they cant figure it out. I plugged this in screenshot the codes. Took it back to the dealership asked them, got answers for each and when asked why, I said. Cuz your incompetent mechanics couldn't diagnose my vehicle. I did, this is what needs to be looked at. Awesome tool, never get ripped off again

It's good.

Powerful tool and software for everythingThis scan tool will connect to anything that can be plugged into. Automotive, Semi trucks, Agricultural machinery, anything. For example, I plugged this scanner into our 2004 John Deere 8320 and I had code reading, data streams and special functions like learning engine torque curve.Plugged it into our 2002 Peterbilt 379 w/Cummins N14 and this scanner was able to tell me that the engine had 6300 hrs on it and that 1900 of those hours were spent at idle.Two years of free software licensing give you plenty of time to make your money back on this kit.Pros:Connects to anythingAny adapter you could ever needWell built and protectedEasy to learn software (hard to master diag but that's just mechanics for you)Android tablet that lets you have other apps and capabilities on it.Cons:Videos online are few and far between for HD side of thingsHD software is really clunky compared to automotive side (Not Launch's fault, just the nature of that side of turning wrenches)Overall worth the money, especially if you're a business owner trying to save money on repairs. Have this tool for our farm because shop rates are $200/hr arond here. Shouldn't take long for this to pay for itself. This isn't just a tool for professionals and shops, this is something that should be invested in to help your farm (or any other business with machines) save money. It'll never make you a single penny, but you'll save lots of dollars.

New to the launch product line. I was very skeptical due to the low cost but, I have used it a couple times with success. Did a caterpillar 7.1 industrial engine, tier 4, today with no issues. It actually communicated with both the ECM and the DEF controller. I'm ashamed to say that my $9000 Bosch won't do that. I was able to pinpoint a NOX issue that was giving EGR codes. I am highly impressed so far. I deal with autos, light and medium trucks occasionally and mostly heavy duty equipment with Caterpillar and Cummins. If you don't specialize in particular equipment make or type there is no one answer but, this is the closest I've come to it for such a reasonable price. I just shake my head at what I've spent in the past. I spend more for my yearly updates than this tool cost.
