The Haldex Controller can be used for all 4 Motion vehicles, original or Standalone.
All connections are Plug and Play except for the standalone functions.
The controller works completely standalone so it does not need the App to function.
When the controller is powered up it starts running the program that was last used.
All settings made in the App are saved to the internal memory of the controller.
