Review on LAUNCH X431 PRO3S+: Upgraded Ver. of X431 V PRO, Bi-Directional Scan Tool with OE-Level Full System Diagnostic Scanner, Key Programming, ECU Coding, AutoAuth for FCA SGW - 2 Years Free Update by Ross Sugden

I'll describe it this way: A scanner that can do it all. the same or more functions than they are. I'm a mechanic mainly working on light duty diesel trucks (Cummins, Powerstroke and Duramax) and for those who are wondering: YES all diagnostic and special functions are available for them. Power Balance, Relative Compression, Noise Test, Injector Balancing Factors, Injector Coding, Actuation Test. Almost all. The best part is the price. This scanner can do the same as the most expensive scanners on the market. The tablet is very fast and responsive and the battery lasts a very long time. A single charge lets you run diagnostics all day with ease. Activating and downloading the software is very easy. For the price and features, this is the best value.
