CONSTITUTION:A trouble information memory device 13 memorizes the data of symptoms and causes of car troubles, together with conditions to be real causes. A trouble information restricting device 19 restricts the data of troubles memorized by the trouble information memory device 13 into the data to be real causes of troubles. Depending on the data of the device 19, causes of input symptoms are inferred at a symptom input device 15, to report the resultant causes. |
