Abstract
A method for operating a motor vehicle with a prime mover (), a transmission (), a driven end (), and a parking lock system () is provided. A shift element () of the transmission () and a parking lock actuator () of the parking lock system () utilize a common pressure control. When the shift element () is actuated with the aid of a pressure control effecting an at least partial engagement of the shift element () and when the pressure control is less than a limiting value for holding the parking lock system () in the disengaged position, the method includes monitoring a parking lock sensor () to determine whether the parking lock sensor () detects a movement of the parking lock actuator () or a signal corresponding to the movement of the parking lock actuator () despite a parking lock detent () having been actuated for locking.
