Abstract
A method for protecting a microcomputer of a control unit for a motor vehicle against the manipulation of a control program that is stored at least partially in a rewriteable memory, by executing a validation program stored in the microcomputer for detecting an unauthorized manipulation of the control program. In order to make possible a simple deactivation of the validation program without impairing the security of the validation program, an electronic hardware identifier of the control unit is provided for identifying the control unit as a serial module or as application module, the validation program being able to be switched from an activated state to a deactivated state in the application module using standard commands and in a serial module only using special measures. The standard commands are freely available, whereas the special measures are available on a limited basis.
