Abstract
In a motor ECU, a motor control unit detects an abnormality when a parking mechanism has not attained a target range within a predetermined period after control of the driving of a motor is started. A data memory unit stores diagnosis information when the motor control unit detects an abnormality. An abnormality check unit compares the state of a changeover mechanism outputted by the motor control unit with the target range and stores diagnosis information in the data memory unit, when the state of the parking mechanism has not attained the target range within a predetermined period after the state of the parking mechanism is outputted and when the motor control unit has not detected an abnormality.
