Failure diagnostic apparatus and method of storing failure information
First Claim
1. A failure diagnostic apparatus, comprising:
- a vehicle-condition diagnostic portion that examines the condition of the vehicle to determine whether a failure has occurred;
a plurality of failure-information storage portions in which, when the vehicle-condition diagnostic portion determines that a failure has occurred, information about the failure is stored;
a diagnostic-environment determination portion that determines a diagnostic environment in which the vehicle-condition diagnostic portion examines the condition of the vehicle; and
a storage selection portion that selects at least one storage portion of the plurality of failure-information storage portions to store the information about the failure, based on the diagnostic environment determined by the diagnostic-environment determination portion.

Abstract
A failure diagnostic apparatus determines the environment in which the condition of a vehicle is examined and selects an appropriate storage location for information regarding the condition of the vehicle. In particular, the failure diagnostic apparatus includes a vehicle-condition diagnostic portion, a plurality of failure-information storage portions, a diagnostic-environment determination portion, and a storage selection portion. When the vehicle-condition diagnostic portion determines that a failure has occurred, the diagnostic-environment determination portion determines the environment in which the condition of the vehicle is examined. Then, based on the diagnostic environment determined by the diagnostic-environment determination portion, the storage selection portion selects at least one storage portion of the plurality of failure-information storage portions to store information regarding the failure.

7. A failure diagnostic apparatus, comprising:
-
a failure-determination portion that determines whether a failure has occurred in the vehicle; a vehicle-environment determination portion; an information determination portion; and a plurality of failure-information storage portions, wherein, when the failure-determination portion determines that the failure has occurred, the vehicle-environment determination portion determines an environment around the vehicle and the information determination portion determines whether information about the failure is first information that is temporarily needed, or second information that is permanently needed, based on the determined environment around the vehicle; and
the first information and the second information are stored in different portions in the plurality of failure-information storage portions. - View Dependent Claims (8)

9. A method of storing information about a failure that has occurred in a vehicle, comprising:
-
examining a condition of a vehicle to determine whether a failure has occurred; determining a diagnostic environment in which the condition of the vehicle is examined; and selecting, when it is determined that a failure has occurred, a storage location to store information about the failure, based on the determined diagnostic environment.
