A method for testing at least two arithmetic units installed in a control unit includes: loading of first test data for testing a first arithmetic unit; saving the loaded first test data in a second memory unit of a second arithmetic unit; switching the first arithmetic unit to a test mode, in which a first scan chain of the first arithmetic unit is accessible; reading the first test data from the second memory unit; shifting the first test data which have been read through the first scan chain of the first arithmetic unit switched to the test mode for providing test result data for the first arithmetic unit; checking the provided test result data for plausibility for providing a test result for the first arithmetic unit.
