Waste of money if the vehicle is newer and has all the safety features like TPMS, ABS, VSC and so on. I bought a professional scanner on Amazon that was cheaper than a full blown pro scanner because it only comes with the software for one manufacturer. It is $10 to download additional manufacturers. It is a good deal for people with only 2 or 3 makes in their driveway. With the pro scanner you can get live data of every system in the car and reset and program just about all of them. It is the Autel Diaglink which is the DIY version of the MD802.
