A method is provided for controlling a friction clutch for connecting first and second rotatable axles in a vehicle, where the clutch includes a first friction part which is connected to the first axle, a second friction part which is connected to the second axle, a spring element which is adapted to bias the second friction part into engagement with the first friction part to connect the first and second axles, and an actuator including a movable actuator part which is engageable with the spring element, and adapted to move, upon being subjected to an actuation force from an actuator control system, towards a disengagement position, thereby deforming the spring element to disengage the second friction part from the first friction part to disconnect the first and second axles. The method includes subjecting the movable actuator part to a test force urging the movable actuator part towards the disengagement position, the test force being smaller than the actuation force, and subsequently or simultaneously to subjecting the movable actuator part to the test force, determining a position of the movable actuator part.
