<p>PROBLEM TO BE SOLVED: To prevent the position of a hydraulic cam rotating motor from being deviated before and after a check by outputting a check signal in either forward or backward direction, which is not locked, to the hydraulic cam rotating motor. SOLUTION: As for the output check of an on-vehicle control computer 10, the check signal is outputted to various on-vehicle actuators including a hydraulic cam rotating motor 26, and the operation of these various actuators is confimed thereby judging whether the check signal is normally outputted from the control computer 10 or not. In this case, a potentiometer 14 for detecting the operating positions of the hydraulic cam rotating motor 26 or various actuators including the hydraulic cam rotating motor 26 is attached, any forward or backward direction, which is not locked, of the hydraulic cam rotating motor 26 is determined based on this detected value and the check signal is outputted from unlocked direction to the hydraulic cam rotating motor 26 so as to operate it.</p> |
