Through the introduction of this text, you will have a certain understanding of technology and architecture of Fcar diagnostic scanner. As an integrated automotive fault diagnostic scanner, Fcar auto scanner needs relevant hardware and software to support all functions, and needs to meet the requirements of various types of auto diagnostic bus, not only adapting to old outdated vehicle bus, but also considering the needs of a variety of new vehicle bus technology. Fcar auto diagnostic scanner developed unique driver interface based on summary of all types of automotive diagnostic interface bus. A detailed introduction of relevant technology will be made in this article.The development of car diagnostic scanner technology Auto fault diagnostic technology develops quickly with the development of electronic technology and auto manufacturing process. The earliest electronic control system based fault diagnosis is: According to ECU internal program for simple fault diagnosis, to display fault through light on and off code. According to light off code, maintenance personnel can locate the fault position, and then diagnose and repair. This is the comparatively old pulse fault diagnostic technology. With the development of electronic technology, there comes portable tester which can not only display diagnostic output value of vehicle-mounted self-diagnostic device, and the user also can input the ECU control parameters. This instrument is to diagnose according to the outside state change, and has data exchange and data storage functions etc.. Through this instrument, series communication can be done to vehicle ECU, and can read fault codes and have real-time reference of ECU internal data, so as to diagnose vehicle fault. With the development of automobile technology, the major motor corporations began to develop new fault diagnostic tools, resulting in a new pattern of automotive electronic device fault diagnosis. With LCD display, these car diagnostic tools have insert of software and cable of connector clip connected to vehicle. When using, connect connector in front end of cable to dedicated connector of vehicle, use fault diagnostic tools that adopt serial communications. Comparing with general diagnostic tools, fault diagnostic tool of serial communication are more convenient and widely used. High-resolution color TFT LCD display, memory capacity up to 4000M, touch screen input, all of which makes Fcar auto diagnostic tool very convenient to use.
