Claim:
1. A vehicle diagnosing apparatus including a computer-readable storage medium with an executable program stored thereon for detecting an abnormality in a first vehicle, the apparatus comprising: a maintenance result finalizing unit configured to read diagnostic information from the first vehicle after a maintenance work is performed on an individual part of the first vehicle, and configured to finalize a result of the maintenance work based on the diagnostic information of the first vehicle after the maintenance work of the individual part; a storage unit configured to store normal value information for determining an appropriateness of the result of the maintenance work finalized by the maintenance result finalizing unit, wherein the normal value information is based on diagnostic information collected from a plurality of vehicles other than the first vehicle; a determination unit configured to automatically determine the appropriateness of the finalized result of the maintenance work with reference to the normal value information in the storage unit, by using an iterative process where the individual part or correlating parts are repeatedly checked to assure completeness of a finalized repair to the individual part; and a notifying unit configured to provide a notification of a result of the determination made by the determination unit and a network interface device configured to transmit abnormality elimination information that indicates the abnormality has been eliminated and that is generated from information of the individual part together with vehicle identification information of the first vehicle to a server from which the normal value information was received, wherein the abnormality elimination information includes information that a diagnosed part indicated by a diagnosis code of an abnormality diagnosis information received from the first vehicle before the maintenance work is performed is different from a diagnosed part that is replaced with a repair part, wherein the diagnostic information, which the determination unit uses with reference to the normal value information to determine the appropriateness of the finalized result of the maintenance work for the individual part, includes diagnostic information from a plurality of the correlating parts that exhibit diagnostic information that correlates with normal-state diagnostic information that the individual part would exhibit during use of the vehicle, and wherein the diagnostic information indicates a location and extent of a failure, the individual part is associated with temporal or spatial restrictions in order to determine the appropriateness of the finalized result of the maintenance work for the individual part, and wherein pattern recognition is used to determine whether the diagnostic information is normal or abnormal, wherein the maintenance result finalizing unit saves information about the individual part in the storage unit when an error amount between the normal value information and the diagnostic information exceeds a predetermined threshold and a probability of an abnormity is determined based on the error amount, wherein a set of the diagnostic information for a plurality of the diagnosed parts that correlate with the individual part is gathered into normal and abnormal groups, and the pattern recognition is used to determine whether the diagnostic information of the plurality of the diagnosed parts is classified into the normal group or the abnormal group to determine whether the repair is complete.
