attachment detection means for detecting whether a first component part has been attached to the vehicle;

abnormality detection means for detecting abnormality of a second component part that is disposed at the first component part; and

abnormality detection prohibition means for prohibiting detection of abnormality or prohibiting transmission of the abnormality information if the attachment detection means detects that the first component part has not been attached to the vehicle,

wherein the attachment detection means detects that the first component part has not been attached to the vehicle, if abnormality is detected in each of a plurality of signal lines of the vehicle-mounted device, the plurality of signal lines connecting the vehicle and the second component part.

9. The failure information detection device according to claim 4, characterized in that the first component part is a bumper, and the second component part is a sensor that monitors surroundings.

5. A failure information detection system in which a failure information detection device detects abnormality of a vehicle-mounted device mounted in a vehicle and transmits abnormality information to a server, characterized in that

the failure information detection device comprises:

attachment detection means for detecting whether a first component part has been attached to the vehicle;

abnormality detection means for detecting abnormality of a second component part that is disposed at the first component part; and

abnormality detection prohibition means for prohibiting detection of abnormality or prohibiting transmission of the abnormality information if the attachment detection means detects that the first component part has not been attached to the vehicle; and

the attachment detection means detects that the first component part has not been attached to the vehicle, if abnormality is detected in each of a plurality of signal lines of the vehicle-mounted device, the plurality of signal lines connecting the vehicle and the second component part.

6. A failure information detection system in which a failure information detection device detects abnormality of a vehicle-mounted device mounted in a vehicle and transmits abnormality of a vehicle-mounted device mounted in a vehicle and transmits abnormality information to a server, characterized in that

the failure information detection device comprises:
