The invention relates to a method for protecting at least one motor vehicle component against manipulation in a control device, which comprises at least one microcomputer (muC) and at least one memory module ( 2, 3 ), characterized in that the code which is necessary for operation of the control device ( 1 ) is divided into at least one master code (MC) which comprises information essential for operation of the control device ( 1 ), and at least one sub-code (SC) which comprises additional information for operation of the control device ( 1 ), at least the master code ( 1 ) being stored in the microcomputer (muC) and the master code (MC) monitoring the manipulation of the sub-code (SC). The invention furthermore relates to a control device for a motor vehicle component which comprises at least one microcomputer (muC) and at least one memory module ( 2, 3 ), the code which is necessary for operation of the control device ( 1 ) being divided into at least one master code (MC) which comprises information which is essential for operation of the control device ( 1 ), and at least one sub-code (SC) which comprises additional information for operation of the control device ( 1 ), and at least the master code (MC) being stored in the microcomputer (muC) and the master code (MC) containing a software function module for detection of manipulation within the sub-code (SC).
