PROBLEM TO BE SOLVED: To provide a vehicle failure diagnosis method capable of detecting a potential failure of a vehicle and performing precise failure diagnosis in a production line or a workshop.SOLUTION: A vehicle failure diagnosis method includes a detection stage in which a control part detects whether or not a failure sign code (REC) occurs, a measurement stage in which the control part measures a time when the failure sign code occurs when the failure sign code occurs as a result of executing the detection stage, a calculation stage in which, after the measurement stage, the control part calculates a percentage of the failure sign code based on the time when the failure sign code occurs and a predetermined setting time, a storage stage in which, after the calculation stage, the control part stores the failure sign code and the percentage of the failure sign code, and an output stage in which, after the storage stage, the control part outputs an output signal for the stored failure sign code and the stored percentage of the failure sign code to a diagnosis device when the control part receives a request signal from the diagnosis device.SELECTED DRAWING: Figure 2

    【課題】車両の潜在的故障を検知して、生産ラインまたはワークショップで精密な故障診断を行うことができるようにする、車両の故障診断方法を提供する。【解決手段】本発明の車両の故障診断方法は、制御部で故障兆候コード(REC)が発生したか否かを検知する検知段階と、検知段階の実行結果、故障兆候コードが発生した場合、制御部が故障兆候コードの発生した時間を測定する測定段階と、測定段階の後、制御部が故障兆候コードの発生した時間と所定の設定時間に基づいて故障兆候コードの百分率を算出する算出段階と、算出段階の後、制御部が故障兆候コードおよび故障兆候コードの百分率を保存する保存段階と、保存段階の後、制御部が診断装置から要求信号を受信した場合、保存された故障兆候コードおよび故障兆候コードの百分率に対する出力信号を診断装置へ出力する出力段階とを含むことを特徴とする。【選択図】図2
