Development History of Auto Diagnosis and Diagnostic Tool

Automobile diagnosis refers to the process of identifying the causes of automobile faults or trouble. OBD diagnostic technology refers to technologies which can detect and analyze fault components and fault areas. Most of Fiberall products are auto diagnostic tool for this field. According to the complexity of automobile diagnostic technology and the development level of automobile technology, there are four diagnostic methods. Artificial experience diagnosis, simple instrument diagnosis, precision detection diagnosis and artificial intelligence diagnosis.

Introduction of Auto Diagnosis

Automobile diagnosis refers to the process of identifying the causes of automobile faults or trouble, that is, locating the faulty parts and identifying the causes of the faults under the condition that the automobile does not disintegrate or only dismantles individual parts.

OBD diagnostic technology refers to technologies that can be used to detect and analyze fault components and fault areas. In fact, the generalized diagnosis includes three aspects: state detection, fault detection and performance prediction. Most of Fiberall products are auto diagnostic tool for this field.

 

Four Main Methods for Vehicle Diagnosis

According to the complexity of automobile diagnostic technology and the development level of automobile technology, there are four diagnostic methods.

A, Artificial experience diagnosis:

Before the 1950s, automobiles had simple structure and fewer electrical equipment. So fault diagnosis could be accomplished by manual experience. At present, the artificial experience diagnosis method is very effective for the diagnosis of some complex faults.

B, Simple instrumental diagnosis:

From the early 1950s to the late 1970s, due to the increasingly complex structure of automobiles, electrical equipment is gradually increasing. Therefore, in the process of automobile fault diagnosis, it is necessary to use simple diagnostic tools. These simple diagnostic tools include vacuum meter, pressure gauge, multimeter and oscilloscope and other instruments. They are able to test the relevant assembly and parts to determine its technical status.

C, Precision detection and diagnosis:

From the early 1980s to the early 1990s, due to the increasing degree of electronization of automobiles, dynamic random faults and functional faults of control systems are increasing day by day. Computer technology become the core detection method. So that the vehicle state detection level and accuracy has been greatly improved. And the accuracy of fault diagnosis also has great improvement. For example, various engine analyzers, computer detectors and various electronic detectors are necessary for precision testing. OBD technology appeared at this period. So obd code reader and obd2 diagnostic scan tool based on obd technology appeared.

D, Artificial intelligence diagnosis:

Since the 1990s, the electronic equipment of automobiles have been increasing day by day. But the models and their control technologies are different. Therefore, fault diagnosis becomes a key issue in vehicle maintenance. Auto diagnosis started to adopt artificial intelligence theory and technology as well as modern information technology. And professional OBD-II EOBD auto diagnostic tool came out at this stage.

 

Latest development of Auto Diagnosis

And after 2004, by using the small vehicle wireless transceiver system, remote communication technology appeared in auto diagnosis. The vehicle body number, fault code and vehicle location will be automatically informed to the management department. This is due to wireless cellular communication, satellite communication or GPS system. With them, the management department is able to issue instructions to the vehicle according to the emission level. Including maintenance suggestions, time limit for solving emission problems, etc. Even the vehicles of those who exceed the limit and violate the regulations will be issued with a prohibition order or punished. Fiberall GPS tracker with OBD2 interface is such an auto diagnostic scan tool for this application.

 

Diagnostic Tool for Auto Diagnosis

Nowadays, OBD vehicle diagnosis technology has been well developed. And the intelligent degree of auto diagnosis is very high, and gradually tends to the unification of international standards. So it is able for different vehicles to complies different diagnostic tools from different suppliers. No matter is it is simple obd diagnostic tool  or intelligent auto diagnostic tool. or IOV diagnostic tool for remote communication. No matter OBD-II or Eobd vehicles diagnosis, Fiberall auto diagnostic tools can be an ideal choice.
