Abstract:
A method for resetting a parking lock operating system for a motor vehicle includes providing the parking lock operating system and switching the parking lock operating system. The parking lock operating system includes a hydraulic fluid supply line with a hydraulic fluid, a base position in which a parking lock is active, and a transport position in which the parking lock is active. The parking lock operating system is switched from the base position to the base position or from the transport position to the base position by, in the following order: increasing a pressure of the hydraulic fluid above a second pressure threshold, lowering the pressure below a first pressure threshold, less than the second pressure threshold, increasing the pressure above the second pressure threshold, and lowering the pressure of the hydraulic fluid below the first pressure threshold.
