Vehicle diagnosis apparatus

摘要

A vehicle diagnosis apparatus includes an accumulation unit and a storage control unit. The accumulation unit cumulatively adds a numerical value indicating a normal operation history of each normal operation made to a vehicle to an initialized cumulative total value having a predetermined number of digits, during a time period from an assembly of a vehicle component to an actual use of the vehicle, and stores the cumulative total value in a non-volatile storage unit. The storage control unit, in response to an abnormality occurrence in the vehicle, stores a corresponding diagnosis code in the non-volatile storage unit. The accumulation unit further cumulatively adds a numerical value indicating the abnormality occurrence to the cumulative total value. The storage control unit stores, in the non-volatile storage unit, the diagnosis code indicating the abnormality occurrence in association with the cumulative total value.

1. A vehicle diagnosis apparatus, comprising:
an accumulation unit cumulatively adding a numerical value indicating a normal operation history of each normal operation made to a vehicle to a cumulative total value, which is initialized and has a predetermined number of digits, during a time period from an assembly of a vehicle component to an actual use of the vehicle, the accumulation unit further storing the cumulative total value to which the numerical value indicating the normal operation history is added in a non-volatile storage unit; and a storage control unit, in response to an occurrence of an abnormality in the vehicle, storing a diagnosis code corresponding to the occurrence of the abnormality in the non-volatile storage unit, wherein the accumulation unit further cumulatively adds a numerical value indicating the occurrence of the abnormality to the cumulative total value stored in the non-volatile storage unit, and the storage control unit stores, in the non-volatile storage unit, the diagnosis code corresponding to the occurrence of the abnormality in association with the cumulative total value to which the numerical value indicating the occurrence of the abnormality is added.
