    • PROBLEM TO BE SOLVED: To accurately diagnose a vehicle by continuously receiving a detection signal before the beginning of diagnosis and expressing its variation in a graph, and setting up a timing for taking-in the detection signal to be used for the diagnosis from the graph expression. SOLUTION: A taking-in timing is previously set up before the beginning of diagnosis. For instance, the detection signal of a water temperature sensor 43 rises at a fixed inclination for a some period after the starting of an engine 4 and then becomes a fixed value. Here, the mean values of the inclination and of a required time are obtained and diagnosed on whether both the mean values are within a set-up normal range or not. An engine 4 is started before the beginning of the diagnosis, and the detection signals of the water temperature sensor 43 are continuously taken into a hostcomputer 3, and their graph is expressed. An operater observes an expression graph to set up a taking-in timing for obtaining the mean value. The timing is set up in this way, and a data transmitting request signal is transmitted to a diagnosis unit 2 at these set-up timings in the case of diagnosis. The setting up of the optimum timing thereby becomes possible.

    • PROBLEM TO BE SOLVED: To simplify the structure of a diagnosis unit by providing the subject device with a portable diagnosis unit and a host computer which receives diagnosis data transmitted from the unit and determines whether a vehicle is normal or not through an analysis of the data. SOLUTION: A portable diagnosis unit 2 is connected to an ECU of each vehicle C through a cable 21. In the vicinity of a vehicle diagnosis line 1 a host computer 3 is installed in order to perform mutual communication between the computer 3 and the unit 2 in a wireless style. In the unit 2 a data buffer 22 which stores diagnosis data read from the ECU at a time and a communication part 23 that transmits the data stored in the buffer 22 to the computer 3 is provided. The computer analyzes the data on receipt of the data and determines whether the vehicle C is normal or not, and records the determination result together with another data such as the number of the vehicle.
