SELF-DIAGNOSING SYSTEM AND METHOD FOR ENGINE ELECTRONIC CONTROLLER

摘要

In order to provide a self-diagnosis system of an electronic control apparatus and a diagnostic method thereof, a control apparatus capable of performing various operations can output the corresponding data by determining an operation state of another electronic control apparatus. Power supply means for supplying power for the apparatus and the self-diagnosis system; An electronic controller unit comprising a plurality of electronic controllers for outputting control signals for performing respective operations of the electronic apparatus; A first interface means connected to the electronic controller to enable data communication with the electronic controller; Is connected to the power supply means and the first interface means, to display the type of the car so as to select the type of the car in order to check the operation state of the electronic control device of the car, the car corresponding to the type of the displayed car When the type of is selected, it displays all the electronic control devices installed in the selected car so that the desired electronic control device can be selected, and when the corresponding electronic control device is selected, it displays the operable functions so that the user can select the desired function. Self-diagnostic control means for performing a selected function when a desired function is selected and stopping the selection operation and performing the previous step when a signal for stopping the selected operation is applied during each operation; Memory means connected to the self-diagnostic control means to store data necessary for operation and to read stored data; Information output means connected to the self-diagnostic control means and the memory means and outputting data applied from the self-diagnostic control means in accordance with a control signal of the self-diagnostic control means; It is connected to the information output means and the self-diagnostic control means, the self-diagnostic control means consists of information input means for inputting the selection data to determine the operating state of the electronic control device of the desired vehicle by performing the selected function have.
