7. A non-transitory computer readable information recording medium storing a fault diagnosis program that, when executed by a processor, performs a method comprising:
receiving input of fault data and observation data, the fault data being obtained from a vehicle when a fault of the vehicle occurs and the observation data being observed in time series by a device of the vehicle until immediately before the fault occurs;
generating feature master data that associates a content of the fault with features, the content of the fault being indicated by the fault data and the features being extracted from the corresponding observation data; and
transmitting the generated feature master data to a target vehicle,
wherein the generated feature master data is configured to equip the target vehicle to detect a sign of a fault in the target vehicle using the feature master data and another observation data obtained from the target vehicle.
