Claim 9:
10. A vehicular diagnostic system including a plurality of vehicles each including a magnetic sensor for detecting a plurality of magnetic markers disposed in a traveling road of the plurality of vehicles, the system comprising:
a server apparatus which acquires detection information of the plurality of magnetic markers by each of the plurality of vehicles and, based on the detection information, generates marker state information indicating a state of each of the plurality of magnetic markers, and
the plurality of vehicles each including:
a communication interface which acquires the marker state information from the server apparatus, wherein the quality information indicating the quality level of the each of the plurality of magnetic markers; and
a computer processor configured to diagnose a state of the magnetic sensor including determining whether the magnetic sensor is normal or an inspection of the magnetic sensor is required, wherein the computer processor uses the marker state information to diagnose the state of the magnetic sensor;
a tag reader configured to perform wireless communication with a wireless tag held by the each of the plurality of magnetic markers and acquire marker identifying information for identifying a corresponding magnetic marker from the wireless tag,
wherein the computer processor is configured to identify the marker state information of the corresponding magnetic marker by using the marker identifying information acquired from a magnetic marker side.
