Abstract
Abstract A system for diagnosing a motor vehicle has a diagnosis device including a computer having a central processing unit and a memory, the memory having a plurality of programs for diagnosing an electronic control system for controlling an engine. An indicator section and a display are provided. The diagnosis device has a control unit. The control unit receives input and output data of an element in the electronic control system and drives the indicator to indicate operating conditions of the element in accordance with the input and output data. On the other hand, the display displays an identification code of the element.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
207 words
A system for diagnosing an electronic control system of an automotive engine mounted on a motor vehicle, the electronic control system having sensing means including switches for detecting operating conditions of the vehicle, means for storing output data from said sensing means and providing control data for controlling the vehicle via actuators, said output data and said control data constituting diagnosis data, the diagnosis system comprising: a diagnosis device including a computer having a central processing unit and a memory connected to said processing unit including a code generating means for generating codes designating selected diagnosis data, the memory having a plurality of programs for diagnosing said electronic control system, and display means for displaying results of the diagnosis followed by said programs; said display means comprising: a plurality of indicators showing conditions of said data; and crystal display means for displaying said codes corresponding to said diagnosis data and having a plurality of cells for storing said codes corresponding to said indicators; and said diagnosis device further including driving means responsive to said codes and said diagnosis data for providing first signals to said indicators and providing second signals to said crystal display means so as to simultaneously display said codes corresponding to said diagnosis data.
Claim 2
