For example, when removing four summer tires to which tire internal pressure sensors are attached and attaching four winter tires to which new internal pressure sensors are attached to this vehicle,
It is necessary to perform a work of associating which internal pressure sensor is mounted on the front, rear, left, and right of the vehicle and on which wheel, and store the identification number of the mounted internal pressure sensor for each wheel in the alarm device of the vehicle. Without this matching work, if there is an abnormality in the tire internal pressure of any of the wheels, the driver can know the identification number of the internal pressure sensor that detected the abnormality, but the driver can determine which wheel is abnormal. I don't know, so it will be difficult to deal with immediately.

However, when the work of associating the internal pressure sensors is performed, the specifications of the internal pressure sensors of the respective wheels and the central alarm device itself, and the communication procedure between the internal pressure sensor and the alarm device are determined by the model of the manufacturer or vehicle. As a result, the work procedure of this associating work and the method of diagnosing the work quality for checking whether the performed work are appropriate also differ depending on the manufacturer and model of the vehicle. It was necessary to prepare a corresponding manual for each type of vehicle and always refer to this manual to carry out the work, resulting in a decrease in work efficiency and work quality.

If this procedure is repeated and the procedure is memorized, the work speed increases and the number of mistakes decreases. However, this requires time and experience to familiarize yourself with this work. There is a problem that it is limited to skilled workers, and even for skilled workers, recently, new models are frequently lined up, and manuals due to specification changes of vehicle models are frequently changed. However, it is not possible to prevent the deterioration of work efficiency and work quality.

As a method of preventing this, there has been proposed a method of visually supporting the work by broadcasting a manual of the work in the form of a demonstration video or the like according to the work contents, but a video tape corresponding to the work is proposed. It took a lot of time and effort to select, and in the case of video broadcasting, it took a lot of time and effort to select a scene to watch and stop the tape there, which was a problem.
