Abstract

A method for detecting addressing errors in an electrical unit. The electrical unit may, e.g., include a central processing unit and modules that respond to the central processing unit via a communication system by means of addresses specific to the modules. Addressing errors caused by faulty modules can be detected. For at least a portion of the accesses made by the central processing unit on one of the modules, an identifier is transmitted from the addressed module to the central processing unit. The identifier transmitted to the central processing unit is compared to a reference identifier. Addressing errors are recognized when the transmitted identifier deviates from the reference identifier.
