摘要

The cause for prolonged diagnosing time can be recognized on a real time basis. A vehicle diagnosing apparatus for diagnosing a vehicle is connected to an electronic control unit mounted on the vehicle. The diagnosing is performed by incorporating data, via the electronic control unit, from various sensors mounted on the vehicle. The apparatus has a timer for measuring the diagnosing time, and a display for indicating measured diagnosing time and judgement results of each of judging items. The judging time for each of the judging items is measured by the timer and the judgement results and the judging time are indicated on a real time basis by the display.
