Understand the difference between traditional automobile maintenance and modern automobile maintenance.

Friends of car maintenance, let's understand the difference between traditional car maintenance and modern car maintenance. It may be helpful for future maintenance. Please see below for details. Traditional automobile maintenance attaches importance to automobile maintenance technology and takes repairing parts as a means. The characteristics of traditional automobile maintenance technology "three-point technology, seven-point tools" The traditional automobile maintenance technical team has two levels: master and apprentice. These two levels are only differences in proficiency, and there is no essential difference. The continuation of traditional automobile maintenance technology is the inheritance of mentoring system. Traditional automobile maintenance is a manual operation skill with mechanical repair as the core. Traditional automobile maintenance emphasizes repair technology, taking parts repair as a means, which is a combination of assembly disassembly and adjustment technology and parts repair technology. The fault inspection of traditional automobile maintenance is mainly qualitative analysis, mainly relying on visual inspection and a small number of instruments. The application of technical data in the process of traditional automobile maintenance is mainly manifested in consulting technical standards, and the form of technical data is technical standard manual. Modern automobile maintenance emphasizes automobile diagnosis technology to judge the fault point. The characteristics of modern automobile maintenance technology are "seven-point diagnosis and three-point maintenance". Modern automobile maintenance is a comprehensive diagnosis technology based on the comprehensive diagnosis of mechanical, electrical and hydraulic systems. The outstanding diagnosis technology of modern automobile maintenance is to accurately diagnose the fault point; Modern automobile maintenance is the combination of assembly disassembly and adjustment technology and system diagnosis technology; The fault diagnosis of modern automobile maintenance is based on quantitative analysis, mainly through instrument detection and local visual inspection. The application of technical data in the process of modern automobile maintenance is mainly manifested in the process of maintenance diagnosis and detailed inspection of technical parameters. Technical data exists in the form of manufacturer's maintenance manual or data CD.
