Classification: CPC G  B | IPC B  G

Claim 11:
12. The vehicular diagnostic system in claim 10, wherein the computer processor is configured to diagnose a change in ground clearance of the each of the plurality of vehicles in accordance with a change in mount height of the magnetic sensor of the each of the plurality of vehicles,
wherein the marker state information includes information indicating a magnetic level of the each of the plurality of magnetic markers, and
the computer processor performs diagnosis of detecting the change in ground clearance of the each of the plurality of vehicles by using an index value indicating a correlation between the magnetic level of the each of the plurality of magnetic markers included in the marker state information and a peak value of a magnetic measurement value measured by the magnetic sensor for the each of the plurality of magnetic markers, and
the index value indicating the correlation is a gradient of an approximate straight line of the correlation, and the computer processor performs a threshold process regarding temporal changes of the gradient of the approximate straight line and generates vehicle information indicating that the change in ground clearance of each of the plurality of vehicles is large when the temporal changes exceed a threshold value.
