A drive system includes a motor having a rotatable output shaft that is operably coupled to a lead screw by a transmission that converts rotary output of the motor into linear translation of the lead screw. The drive system further includes a position sensor configured to sense a position of the lead screw. A method for determining a backlash of the drive system includes the steps of sensing an initial position and driving the lead screw in a first direction to a calculated second position by controlling the motor to rotate the output shaft an amount that corresponds to a distance between the initial position and the calculated second position. The method further includes the steps of sensing an actual second position of the lead screw; and determining a backlash value according to a difference between the calculated second position and the actual second position.
