PROBLEM TO BE SOLVED: To provide a vehicle diagnostic device and a vehicle diagnostic system capable of diagnosing abnormality of a plurality of devices mounted on a vehicle and allowing a user to surely recognize that abnormality has occurred in the devices.SOLUTION: An ECU 200 includes: a notification instruction unit 312 for, in the case an abnormality code is stored in a backup RAM 320, instructing an operation to an MIL 140; a deletion request determination unit 315 for determining whether or not a deletion request signal is received from a scan tool 400; a deletion processing execution unit 316 for executing deletion processing in which the backup RAM 320 is brought into a state where the abnormality code is not stored, based on the determination by the deletion request determination unit 315 that the deletion request signal is received; and a deletion processing prohibition unit 317 for prohibiting the execution of the deletion processing by the deletion processing execution unit 316 for a predetermined period, after the deletion request determination unit 315 determining that the deletion request signal is received.SELECTED DRAWING: Figure 1

    【課題】車両に搭載された複数の機器の異常を診断し、機器に異常が発生していることをユーザに確実に認識させることができる車両用診断装置及び車両用診断システムを提供する。【解決手段】ECU200は、バックアップRAM320に異常コードが記憶されている場合にMIL140に動作を指示する報知指示部312と、スキャンツール400から消去要求信号を受信したか否かを判定する消去要求判定部315と、消去要求判定部315によって消去要求信号を受信したと判定されたことに基づいて、バックアップRAM320を異常コードが記憶されていない状態にする消去処理を実行する消去処理実行部316と、消去要求判定部315が消去要求信号を受信したと判定した後に、消去処理実行部316による消去処理の実行を所定期間禁止する消去処理禁止部317と、を有する。【選択図】図1
