An indicator indicates a vehicle state value in accordance with a rotational position between a zero position and a maximum position. A step motor rotationally drives the indicator on application of a drive signal in accordance with an electrical angle to a field winding. A control unit that controls the electrical angle of the drive signal applied to the field winding performs a leave-zero control operation which varies the electrical angle to rotate the indicator from the zero position to the maximum position and determines presence or absence of abnormal rotation of the indicator based on the electrical angle at the time of detecting the stopping of the indicator during the leave-zero control operation.
