Automotive came out and in use in a variety of reasons inevitably to failure, so the car power, economy, handling stability, using the changes in security. Some unexpected car trouble, some are evolving. When the car fails, experience and scientific knowledge can be used quickly and accurately diagnose the cause of the malfunction, to identify the damaged components and parts, and troubleshooting as soon as possible, the use and maintenance of the car benefit. We often use diagnostic techniques have launch x431, lexia3, mb star.

Car, this modern means of transport, from the manufacturing factory of the day, no matter how they talk, there is a certain life. No matter how used, sooner or later are to be bad, so do not use the failure is relative, and a variety of fault occurrence is inevitable. Therefore, the reasons for failure analysis and diagnosis, help to make judgments, so that car in good condition in the case of technology running.

Global automotive industry speed the development of rapid hair, endless variety of high technology, automotive safety, performance, comfort and so on rising. launch x431 is an indispensable technology. Automotive electronic control system with the continuous development of automotive fault diagnosis more complex and difficult, for the rapid, simple, direct knowledge of such failure and determine the type of substance and because of information, resulting in the car decoder, but with decoder technology, and now the car has been slow, said decoder fault diagnosis of the car computer, and the special computer.

Car fault diagnosis fault diagnosis through the car seat computer connected to the car, through the fault diagnosis of computer operating systems and car models to match the built-in software, read the car data, then the control fault code and based on experience, can easily know all cars the work of the system to accurately determine the fault location and specific fault conditions, failure to quickly rule out a powerful car technical support.

When the car’s electronic control system failure, a system the control unit ECU, PCM or ABS modules for self-diagnosis system components module detects fault, the fault information is stored in digital code modules in-house expertise in the area, this fault code we often called fault code. Car fault diagnosis by using computers and other equipment can be read, analyze and judge the car to a specific fault.

Car computer that can read car fault diagnosis fault code, clear trouble code, data flow, component test, maintenance light zero, read the computer version, the basic set and match to adjust, some automotive fault diagnosis computer can also provide value-added services such as car fault diagnosis expedition, vehicle maintenance information, trouble code table, customer records management, business functions.

Fault Diagnosis of Automobile links computers and cars there are two main methods, namely, wired and wireless. Do not overlook the use of lexia3. Through the diagnostic connector and cable link cable to connect the computer and automotive diagnostic diagnostic Block, and the wireless link that eliminates the need for intermediate line, in the diagnosis of seat location connected to a wireless transmitter devices, diagnostic computer terminal connected receiver, usually for the Bluetooth wireless equipment.

Diagnosis of early cars are basically using the open source computer operating system LIUX, manufacturers develop their own operating system and software, low frequency processing unit, in terms of looks and handling performance, it failed to reach everyone understood computer level. With the computer technology and the Windows operating system, development, and now computers are basically car fault diagnosis using Windows operating system, can truly be called a computer.

Computer for car fault diagnosis fault diagnosis in automobile seat and the car ECU and other mainframe computer communications, automotive fault diagnosis then the computer must follow the relevant standards and protocols, such as OBD.

Fault Diagnosis of Automobile manufacturers of computer based vehicle configuration and the test is divided into dedicated, expert-level troubleshooting computers and original car. Special Purpose Vehicle Diagnosis Computer models only operate for the set, original only automotive manufacturer to operate their own vehicles, and the market is most used in automotive fault diagnosis expert computer, computer expert automotive fault diagnosis fault diagnosis are generally professional development and production of computer companies, as measured by more than models, software upgrades faster, affordable and well received by several maintenance personnel favorite.

Market, in addition to original computer car fault diagnosis, the main vehicle computer fault diagnosis of meta-sign for the domestic brands, car, Dr. Kinder, car repair Wang, Jin Pentium, United iT, Ai Fuka, Motorola, so many foreign Bosch’s such as Germany, the United States SPX and red boxes, Sweden AUTODGAGNOS so. Better technologies mb star.

As the use of computer technology, automotive fault diagnosis and more advanced computer technology, automotive repair methods and philosophy radical political reform is taking place. If in the future for troubleshooting computer anytime, anywhere Internet access, a key upgrade, all kinds of vehicle maintenance equipment and functions into one unified platform, maintenance and integration of resources.
