| Summary: | 碩士 === 國立虎尾科技大學 === 機械與機電工程研究所 === 98 === The primary purpose of this paper is developed an application program for reading Open Diagnostics data eXchange (ODX) document. A vehicle network tool - Vector’s CANdelaStudio Version 5.5 can be used to edit the diagnostic data and can export ODX files for testing and authentication. The Microsoft Visual Studio 2005 Integrated Development Environment(I.D.E.) and .NET Framework are used as development tools. Besides, the C++/CLI is being used as the programming language. The development application program applies only to ISO 14229-1(Unified Diagnostic Services, UDS) and ISO 14230 (Keyword Protocol 2000, KWP 2000) protocols.
After loading the ODX file, the application program parses diagnostic information like Request, Positive Response, Negative Response, DTC (Diagnostic Trouble Codes), Service and Service sub-function. Then, the parsed data can be displayed in the window forms.
The application program developed in this study can display all kinds of information which the ODX files can offer in several pages on the window form, allowing the vehicle-related worker easily viewing the ECU diagnostic information, which leads to increase the working efficiency and reducing the repairing time in increasingly digitization vehicle industry. Furthermore, it can assist the maintenance personnel to quickly and accurately diagnose the vehicles equipped with diagnostic information of the open data exchange documents.
