Abstract: A method for controlling a system for a motor vehicle is disclosed. The system includes an actuator, a volatile memory (RAM) in which an item of position information of the actuator (IPRAM) is stored, and a long-term memory (EPROM). The following are stored in the long-term memory (EPROM): at least one item of position information (IPROM) of the actuator and an item of information relating to the powering down of the actuator (IHT), which assumes a first value (v1) when the system has been powered down in a controlled manner and assuming assumes a second value (v2) when the system has suffered a fault causing the current value of the position of the actuator stored in the volatile memory (RAM) to be deleted.

Abstract: The invention concerns a method for controlling a system (1) for a motor vehicle, said system comprising at least: —an actuator, —a volatile memory (RAM) in which at least one item of position information of the actuator (IPRAM) is stored, —a long-term memory (EPROM) in which the following are stored: o at least one item of position information (IPROM) of the actuator, o an item of information relating to the powering down of the actuator (IHT), this item of information assuming a first value (v1) when the system has been powered down in a controlled manner and assuming a second value (v2) when the system has suffered a fault causing the current value of the position of the actuator stored in the volatile memory (RAM) to be deleted, in particular when the system has stopped being powered electrically as the result of an error, or communication between the system and a computer has been cut off as the result of an error.
