With the ignition on position two, connect the BAS2 RRC to the diagnostic port.
Once connected you can launch the BAS2 RRC app and click Search for tool at the bottom.

Make sure when you connect to the BAS2 RRC for the first time you have internet access on your mobile device so it can download any settings files or updates needed.

Once the tool is logged on you will be presented with the main menu, within the main menu options you will also find sub menus with more options inside.
