Abstract
A method for maintaining an actuator for an airbag control device. The method has a step of impressing an electric current flow through the actuator using an electric voltage having a voltage value. In addition, the method has a step of ascertaining an electric measuring current through the actuator. Here, the electric measuring current through the actuator occurs on account of the impressed electric current flow through the actuator. In addition, the method has a step of executing a comparison of the electric measuring current through the actuator to a threshold value. Moreover, the method has a step of adjusting the voltage value of the electric voltage for impressing the electric current flow through the actuator as a function of the comparison.
