Abstract
An electronic control unit includes a controller configured to interrupt a failsafe relay for a predetermined time period while an external load, such as an electric servo motor, is in a non-operating state and to perform a diagnosis of a short-circuit fault, which may occur at a load power supply line, based on a difference between a first voltage applied to a positive power supply line and a second voltage applied to the load power supply line.
