Abstract
A method and an arrangement for monitoring a computing element in a motor vehicle are suggested. The computing element generates, with the aid of the program modules, at least one output quantity for controlling at least one function in the motor vehicle in dependence upon at least one input quantity. At least one program module or at least a part thereof is selected for monitoring the correct function of the computing element (12). This at least one selected module or the at least one selected part thereof or a copy is run through in the computing element (12) on the basis of test data and the result of the test data computation is compared to a pregiven result for fault detection.
