Abstract
A range switching device may switch a shift range despite resetting and restarting of a controller. When the controller is reset and restarted during a switching operation of the shift range and the shift range before or after being switched is a P range, the controller controls a motor to rotate the motor until a range switching mechanism abuts against a first limit position of a movable range of the range switching mechanism and learns a rotation position of the motor as a reference position of the motor. When the shift ranges before and after being switched are the ranges other that the P range, the controller controls the motor to rotate until the range switching mechanism abuts against a second limit position of the movable range and learns the rotation position of the motor as the reference position.
