Description

자동차용 전자장치의 고장진단시스템Fault diagnosis system of automotive electronics

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 이 발명의 자동차용 전자장치의 고장진단시스템의 한 실시예의 구성을 표시한 블럭도.1 is a block diagram showing the configuration of one embodiment of a failure diagnosis system for an electronic device for a vehicle according to the present invention;

Claims (1)

항시 고장진단 결과를 온-오프 신호로 출력시키는 자동차에 탑재한 복수의 전자장치. 이 전자장에서 출력되는 고장진단 결과의 온-오프 신호를 제1의 코넥터를 경유하는 수신하며 판정결과를 표시하는 제1의 테스터, 상기 각 전자장치에서 출력되는 상기 온-오프신호에서 시리얼 신호로 전환시키고 또는 상기 제1의 코넥터의 소정의 단자 위치에 대응시켜 배선하여 제1의 테스터에 이 시리얼 신호의 도입을 저지하는 제어선, 상기 시리얼 신호를 사용하여 상기 각 전자장치의 고장 진단시 이 시리얼 신호를 상기 제어선을 통하여 도입시키는 제2의 코넥터, 상기 고장진단시 상기 제어선에 접속시키는 제3의 코넥터를 통하여 상기 시리얼 신호를 입력시키며 또 제2 및 제3의 코넥터를 접속시켰을 때 상기 제어선의 제압레벨을 바꾸어 상기 각 전자장치에서 출력하는 온-오프신호 각 전자장치에 시리얼 신호로 변환시켜 고장진단을 행하는 제2의 테스터를 구비하여서 된 자동차용 전자장치의 고장진단시스템.A plurality of electronic devices mounted in a vehicle that always outputs a fault diagnosis result as an on-off signal. A first tester which receives the on-off signal of the fault diagnosis result output from the electromagnetic field via the first connector and displays the determination result, and converts the on-off signal output from each of the electronic devices into a serial signal; A control line for preventing the introduction of the serial signal to the first tester by wiring the wiring to correspond to a predetermined terminal position of the first connector; A second connector for introducing the serial signal through the control line, a third connector for connecting the control line to the control line when the fault is diagnosed, and when the second and third connectors are connected, A second diagnosis is performed by changing the overpressure level and converting the on-off signal outputted from each electronic device into a serial signal to each electronic device for fault diagnosis. Fault diagnosis system for automobile electronic device equipped with tester. ※참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is to be disclosed based on the initial application.
