    摘要： A checking ECU 45 controls, in step S11, an electromagnetic clutch 31 into a disconnected state in a state where a turning electric motor 22 is stopped, and acquires a steering angle θ and a steering torque T in step S12. The checking ECU 45 determines in step S13 whether or not the steering torque T is equal to or less than a target torque To. When the steering torque T is equal to or less than the torque To, the checking ECU 45 proceeds to step S14, and sets an anomaly flag MBF to “0” indicating that the clutch 31 is normal. Meanwhile, when the torque T is determined in step S13 to be greater than the torque To, the checking ECU 45 proceeds to step S15, and sets the flag MBF to “1” indicating that the clutch 31 is anomalous. This anomaly determination is executed when the steering angle θ is determined in step S16 to be equal to or less than a predetermined steering angle θo.
