Depending on the vehicle, the central signal acquisition and actuation module (SAM control unit) or the rear signal acquisition and actuation module reads in the status of the respective trunk lid/tailgate lock switch. In addition, the central signal acquisition and actuation module or the rear signal acquisition and actuation module actuates the trunk lid/tailgate lock motor accordingly.
