The present invention provides a protective maintenance service system capable of raising an alarm for the replacement of a part when the degradation of an inspection required part reaches the prescribed criteria of replacement. Of the respective inspection required parts stored in the vehicle inspection parts database for the respective vehicles stored in the vehicle database provided by a business unit in advance, the time of part replacement is determined on the basis of the data detected by a part condition sensor for a part having a part condition sensor, and on the basis of the time, which is obtained from the service life compensated with an actual service environment, for a part without a part condition sensor.
