VEHICLE AND VEHICULAR DIAGNOSTIC SYSTEM

A vehicle including a magnetic detecting part for detecting a magnetic marker disposed in a road is configured to acquire marker state information indicating the state of the magnetic marker from an external server apparatus via wireless communication and diagnose the state of the magnetic detecting part by using a result of detection of the magnetic marker in which the state of the magnetic marker indicated by the marker state information is good, thereby allowing inspection cost and cost of maintenance of the magnetic detecting part for detecting the magnetic marker to be suppressed.
