The media could not be loaded. 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!

This thing is the absolute goat ! It’s got full support on the heavy duty side , you can do just about anything except update ecm with manufacture software . Other than that ,it’s full support …air handling performance test , install and calibration of vgt actuators, injector performance test , testing nox sensors , full transmission support ….. the list goes on. Trailer abs … Cummins , Kubota , (((( anything ))))) I’m in love with it

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.
