PROBLEM TO BE SOLVED: To provide an on-vehicle troubleshooting system capable of identifying a problem when a vehicle gets a trouble and carrying out inspection on items to be inspected following an inspection procedure.SOLUTION: When abnormality is detected in a diagnostic result on at least one of plural electrical units, each of plural electronic control units 21, 22, 23, 24 and 25 transmits a diagnosis code informing contents of the abnormality to an on-vehicle network 3. When receiving the diagnosis code from the on-vehicle network 3, a failure diagnosis electronic control unit 4 executes an inspection item and an inspection procedure associated with the diagnosis code by data-transfer to the electronic control units 21, 22, 23, 24 and 25.SELECTED DRAWING: Figure 1

    【課題】自動車の故障時に、不具合を特定し、点検項目を点検手順に従って点検することができる車載故障診断システムを提供する。【解決手段】複数の電子制御ユニット21,22,23,24,25の夫々は、複数の電装品の診断結果の少なくとも一つに異常がある場合に、車載ネットワーク3に異常の内容を知らせるダイアグコードを送信する一方、故障診断電子制御ユニット4は、車載ネットワーク3からダイアグコードを受信した場合に、ダイアグコードに関連付けられた点検項目及び点検手順を電子制御ユニット21,22,23,24,25との間のデータ転送によって実行する。【選択図】図1
