This invention relates to a method for defining absolute position information of an elevator car (102). The method comprises: obtaining (202) continuously a pulse position information of the elevator car (102); and defining (204) an absolute position information of the elevator car (102) by adding a predefined correction value to the obtained pulse position information of the elevator car (102). The predefined correction value indicates a drift between the obtained pulse position information of the elevator car (102) and the actual pulse position of the elevator car (102). The invention also relates to a safety control unit (104) and an elevator system (100) performing at least partly the method.
