Two activated functionalities are using the same
actuators or sensors connector pins:
Verify that no connector pins are shared be­
tween activated functionalities
Check if there are no unwanted functionalities
enabled through the parameters
Disable functionalities until the error is resolved
to pinpoint conflicting functionalities
