Review on 🔧 2022 XTOOL Anyscan A30M Wireless BT OBD2 Scanner: Android & iOS, Bi-Directional Scan Tool with All Systems Diagnostics, ABS Bleeding, 21 Services - NO Update Fee! by Jon Robertson

I'm amazed at all the features this thing has. This is the ideal price to give tech-savvy home mechanics the opportunity to upgrade their diagnostic tools. I was able to confirm that my Trailblazer 07 EVAP system is finally sealed. I found a faulty purge valve that is constantly sucking vacuum into the tank. The computer saw it as a large evaporator leak. With this tool I was able to open (close) the vent valve, turn off (close) the purge valve, and see that the tank gauge was still holding a vacuum. Replaced the vent valve, ran the same test and now I can see the pressure building in the tank as the fuel releases vapors. repair done! If you are in doubt about buying a bi-directional tool, this is what you need. It should be noted that I initially had trouble connecting to Bluetooth and getting the app to see the key. Do yourself a favour: After activating the app and doing the initial Bluetooth pairing, restart your phone and disconnect the dongle, then boot everything up and reconnect the dongle. Then it seemed that he made a connection every time.
