A device () for activating an electrical consumer () includes a controllable current source () for providing a control current, a switching unit () for controlling a consumer current as a function of the control current, and a sampling unit () for determining a time delay between an activation of the current source () and the enabling or interruption of the current flow by the switching unit (). Furthermore, a processing unit () is provided, which is configured to determine that the current source () is defective if the time delay lies outside a predetermined range.
