1. A method of activating an active discharge circuit to discharge a capacitive energy storage of at least one electrical consumer of an on-board power supply for a motor vehicle, an energy source for the on-board power supply is to be activated or deactivated, the method comprising:
by a control device execute a process to,
receive a signal to activate the active discharge circuit,
before an activation of the active discharge circuit after receiving the signal, perform an examination if the energy source is deactivated according to at least one first criterion, and
activate the active discharge circuit only upon satisfaction of a condition that the energy source is deactivated according to the at least one first criterion.
