Abstract

A method for testing the operation of a capacitive anti-trap system for an adjustable vehicle closing element actuated by external force, such as a side door, a window, a sunroof or a tailgate, wherein a body opening of a vehicle can be locked in a closed position and that is can be moved into a closed position by a motorized drive unit. The capacitive anti-trap system is configured for detecting the trapping of an obstacle when closing the vehicle closing element by evaluating an electrical capacitance that is changed by the obstacle. The electrical capacitance, which also changes when the vehicle closing element is opened, is evaluated on the basis of at least one measured value in order to test the proper operation of the anti-trap system.
