METHOD AND APPARATUS FOR TESTING HARDWARE DEVICES IN ELECTRIC SYSTEM

摘要

A method and a device for testing hardware devices of an electric device are provided to output a test result to easily check an abnormal state while testing each hardware device with minimum hardware resources. A memory(23) stores a hardware test program. A controller(22) processes a test for each hardware device(21) by executing the hardware test program and generates a signal having a frequency corresponding to the hardware device generating an error if a test request signal is received. The frequency is differently set to each hardware device.
