First Claim
1. An electronic control unit comprising:
- an abnormality determiner configured to determine an abnormality of a vehicle by performing an abnormality diagnosis;
a first storage configured to store a readiness information, the readiness information (i) indicating that the abnormality determiner has performed the abnormality diagnosis for all of a plurality of abnormality diagnosis items and (ii) indicating that the readiness information is complete; and
a second storage configured to store a history of the abnormality diagnosis, the history of the abnormality diagnosis including information of whether a normal history exists indicating that a normal condition of one of the abnormality diagnosis items is satisfied, whereinthe abnormality determiner is further configured todetermine whether the history of the abnormality diagnosis including the information of existence of the normal history is stored in the second storage when the abnormality determiner performs the abnormality diagnosis,use a relaxed condition in place of the normal condition for the abnormality diagnosis item during the abnormality diagnosis when the history of the abnormality diagnosis including the information of existence of the normal history is stored in the second storage, whereinwhen the abnormality determiner uses the relaxed condition during one or more controls being performed in the vehicle while performing the abnormality diagnosis, the abnormality determiner completes and stores the readiness information more quickly using the relaxed condition than when the abnormality determiner uses the normal condition while performing the abnormality diagnosis, wherein the relaxed condition has fewer items and/or more easily completed items than the normal condition.

Abstract
An electronic control unit improves a serviceability for a user of a vehicle by performing an abnormality diagnosis of the vehicle based on (i) storing a readiness information indicating that readiness is complete in a readiness storage, (ii) storing a history of normal diagnosis results from an abnormality diagnosis in a history storage, and (iii) relaxing a readiness complete condition for storing the readiness information in the readiness storage under control of a microcomputer, when the history stored in the history storage includes information of existence of the normal history. By using the relaxed condition for the abnormality diagnosis, readiness information is more quickly stored when performing the abnormality diagnosis. Also, diagnostic process is completed more quickly, facilitating the repair process and enabling the user to more quickly receive a desired service.
