Abstract
PURPOSE:To guarantee a diagnosis program and to evade a destructed program from being executed, that is, a runaway state, by executing self-diagnosis by sum check prior to the execution of the diagnosis program. CONSTITUTION:When a hardware function diagnosis program is loaded on a memory in a device to be inspected, a sum value at every hardware function diagnosis program is calculated and stored, and when the hardware function diagnosis program is executed, the sum value is calculated by reading out from the memory, and a stored sum value is compared with it. And when a normal compared result is obtained, the sum value is calculated by executing the hardware function diagnosis program, and the stored sum value is updated, and also, when an abnormal compared result is obtained, no hardware function diagnosis program is executed. In such a way, it is possible to evade the runaway of the diagnosis program.
