To diagnose a possibility that a vehicle has been exposed to sand dust before the vehicle undergoes a failure.SOLUTION: A vehicle diagnostic device diagnoses at least one vehicle mounted with an engine. The vehicle has a moisture sensor which is arranged inside an engine compartment and detects moisture. When intake pressure of the engine is higher than a predetermined value and the moisture sensor detects the moisture, the vehicle diagnostic device determines a possibility that the vehicle is exposed to sand dust. Thus, the vehicle diagnostic device can diagnose the possibility that the vehicle has been exposed to sand dust before the vehicle undergoes a failure.SELECTED DRAWING: Figure 3 【課題】車両に故障が発生する前に車両の砂塵暴露の可能性を診断する。【解決手段】エンジンを搭載する少なくとも１つの車両を診断する車両診断装置であって、車両は、エンジンコンパートメント内に配置され水分を検知する水分感応センサを有し、エンジンの吸気圧が所定値より高く、且つ、水分感応センサによって水分が検出されたときには、車両に砂塵暴露の可能性があると診断する。これにより、車両に故障が発生する前に車両の砂塵暴露の可能性を診断できる。【選択図】図３
