Abstract
A method checks a functionality of a solenoid valve for a brake system in a motor vehicle. The solenoid valve includes an armature and a coil. The armature, on actuation of the solenoid valve, is moved by a magnetic field of the coil, reducing an air gap of the solenoid valve defined by a position of the armature. The method includes measuring an electric current during the actuation of the solenoid valve, analysing a characteristic of the electric current during the actuation of the solenoid valve, and assessing the functionality of the solenoid valve based on the analysis of the characteristic of the electric current.
