Abstract

본 발명은 자동차의 엔진 전자제어수단을 테스트하는 장치에 관한 것으로 테스트장치내에 엔진 전자제어장치의 양부를 판별할 수 있는 프로그램을 내장하여 프로그램의 작동에 따라 데이타 인풋값을 엔진 전자제어장치에 입력하고 여기에서 출력되는 데이타값을 테스트장치의 마이크로프로세서에서 분석하여 양품일 경우 양품임을 디스플레이하고 불량품일 경우 불량품임을 디스플레이토록함으로써 엔진 전자제어장치의 정상여부를 쉽게 판별할 수 있도록 한 것을 특징으로 하는 엔진 전자제어수단 테스트 장치에 관한 것이다.The present invention relates to an apparatus for testing the electronic control means of the engine of a vehicle. The program includes a program for determining whether the electronic control device of the engine is built in, and inputs data input values to the engine electronic control device according to the operation of the program. By analyzing the data value output from the microprocessor of the test apparatus, if it is a good product to display a good product, if it is a bad product to display the defective product, the engine electronics, characterized in that it is easy to determine whether the engine electronic control device normal A control means test apparatus.
