ABSTRACT:
A configuration is provided in which detected torque values detected by a main torque sensor and a sub-torque sensor in such a state that a predetermined torque including zero is applied are captured, a calculation of a torque difference is repeated a plurality of number of times, an average value of an absolute value of a torque difference which is calculated each time is obtained, this average value is written to be stored in an EEPROM, and a threshold value used for the failure determination is corrected based on the stored value.
