Enable iCube II in Options > iCube Configuration.
Use the iCube II dedicated dongle.
Ensure iCube II is positioned within ~10 meters of the programming computer.
Run an iCube II check which can be found in the Options > iCube Configuration menu. If the iCubeII check kcannot locate the iCube II, try deleting the iCube II from Unitron TrueFit and adding it back again using the Add iCube... button.
