Auto Fault Self-diagnosis

Vehicle maintenance is beyond the core machinery repair manual abilities, the primary focus on vehicle maintenance technology, and also to repair parts for that major maintenance technology, but additionally set up and disassembly tactic to adjust the mixture of parts repair process. The various tools we are able to use to produce x431, lexia3, megabytes star.In comparison, the current automobile maintenance is dependant on mechanical, electrical, hydraulic integration from the core from the comprehensive system diagnostics diagnostics.

Automobile Maintenance prominent diagnostic techniques, and also to precisely identify problems because the goal, fully showing the “seven diagnostic, one-third of repair” from the modern vehicle maintenance techniques an effect, many electronics companies have coveted cars, and equipment maintenance marketplaces, allow us to satisfy the near future automotive self-diagnosis tasks.

Within the solid foundation of growth and development of automotive electronics automobile self-diagnosis function. Don’t disregard the launch x431 useful.Forever of electronic technology and vehicle technology combination, the electronic technology within the vehicle around the progressively number of programs, mainly in the area of electronic technology of integrated circuits, large-scale integrated circuits and VLSI development, a vehicle special deals functionality, reliability, fast response, inexpensive of automotive electronic control systems.

However, the electronic vehicle control, but additionally introduced new problems. First, automobile electronic control systems be complex, increasingly more difficult vehicle maintenance, vehicle maintenance capacity of technical employees are relatively elevated other hands, the electronic control system security debugging features to avoid vehicle because electronic control system itself fails, leading to vehicle pollutants control and may not run.

Therefore, to be able to deal with situations like these, automotive electronic control technology R & D personnel, performing Vehicle Electronic Control System design, while growing fault self diagnosis system. It may run the procedure within the automotive electronic control systems continuously monitor, including: engine start, engine, electronic ignition, fuel injection along with other system operation status.

Once Fashengyichang situation, Zaigen Ju-specific calculations calculate Chujutidi Guzhang reasons, and also to Dai Ma Xingshicunchu within the driving system (or Chen traffic black box), as the corresponding fault Yunxing module Gongneng start, Shi Chan Sheng failure of Qi Ju Neng to correct look for maintenance, and technical maintenance personnel may use the automobile self-diagnostic function to obtain the fault code for that failure to precisely repair fast.

The fundamental principle of fault self-diagnosis and composition. Reliability and simple maintenance from the purpose of view, automotive electronic control system ought to be outfitted with self-diagnostic function because the eighties GM automobiles the U . s . States developed the very first inside a new electronic control system malfunction self-diagnostic function to include, the worldwide world-class vehicle producers emulate, have created in a variety of electronic control systems outfitted having a fault within the self-diagnostic function following a lengthy duration of development, self-diagnostic module won’t address the security of automobile electronic control systems and vehicle storage memory failure also in a position to provide immediate vehicle created by a number of system operation parameters. Also noted that using what tools, for example lexia3 useful.Because then, the “vehicle fault self-diagnosis function” is just about the new vehicle factory and vehicle repair workshop fault recognition problem indispensable assistant.

Since that time, the “vehicle fault self-diagnosis function” is just about the new vehicle factory and vehicle repair workshop fault recognition problem indispensable assistant.

Presently, for sensors, electronic control systems, implementation from the components are three types of monitoring products to identify the fault reason, fault self-diagnosis module to a new response measures:

Once the vehicle of the sensor or circuit failure, its signal can no more control parameters of the vehicle, to vehicle to operate continuously, fault self-diagnosis enter in the memory module did hand out pre-set transfer the expertise of value as input parameters from the circuit response, the car is constantly operate very quickly.

Once the electronic control system itself produces failure, fault diagnosis module will Chufabeiyong control loop response of Jiandan right control, cars can Kaidao repair scheduled maintenance emergency known as fault “Auto failure limp “feature.

Once the vehicle happened with an implementation from the aspects of unknown reason for the malfunction may lead to damage or serious effects for other components, safe, self-diagnostic module to consider certain safety precautions, the implementation of certain functions instantly stop, this function is known as fail-safe.And to consider using megabytes star. For instance: Once the ignition failure, fault self-diagnosis module stop the fuel injection system offers the energy to suspend the fuel injection nozzle supply, restrain the gas mixture isn’t burning completely in to the exhaust system to lessen accidents happened.
