现在汽车已经是家家户户都拥有的一件交通工具，但是在使用过程中由于各种各样的原因，不可避免的会发生故障，
济南宝马汽车专修小编整理了一些汽车故障诊断方法给您作参考。
Now the automobile is a vehicle owned by every household, but it will inevitably break down due to various reasons in the use process. BMW Jinan has compiled some automobile fault diagnosis methods for your reference.
汽车故障诊断指的是当汽车存在故障隐患，技术状况变差，或是已经部分或完全丧失工作能力，在不解体（或仅卸下个别小件）条件下，为确定汽车技术状况或查明故障部位、原因进行的检测，以及分析与判断。
Vehicle fault diagnosis refers to the detection, analysis and judgment for determining the vehicle technical status or finding out the fault location and cause without disassembling (or only removing individual small parts) when the vehicle has potential faults, the technical status has deteriorated, or the vehicle has partially or completely lost its ability to work.
人工诊断法
Artificial diagnosis
人工诊断主要是凭借诊断人员的实践经验和知识，借助简单工具，用眼看、耳听、手模等感官手段，边检查、边试验、边分析，进而对汽车技术状况做出判断。这种方法简便直观，也是建立现代故障诊断系统知识库的基础。
Manual diagnosis mainly depends on the practical experience and knowledge of the diagnostic personnel, with the help of simple tools, by means of eyes, ears, hand models and other sensory means, while checking, testing, analyzing, and then making judgments on the technical status of the automobile. This method is simple and intuitive, and it is also the basis of building the knowledge base of modern fault diagnosis expert system.
仪器设备诊断法
Instrument and equipment diagnosis method
仪器设备诊断法是采用通用或专用的仪器设备检测汽车、总成和机构，为分析汽车技术状况和判断故障提供定量依据。一些采用计算机控制或配置故障诊断系统的仪器设备可以自动完成汽车技术状况诊断参数的测试、分析、判断和处理决策。仪器设备诊断法客观、定量、检测速度快，促进了汽车诊断技术的发展和应用。
Instrument and equipment diagnosis method is to use general or special instruments and equipment to detect automobiles, assemblies and mechanisms, and provide quantitative basis for analyzing automobile technical conditions and judging faults. Some instruments and equipment controlled by computers or equipped with fault diagnosis expert systems can automatically complete the testing, analysis, judgment and processing decisions of the diagnostic parameters of automobile technical conditions. The instrument and equipment diagnostic method is objective, quantitative and fast, which promotes the development and application of automobile diagnostic technology.
在诊断实践中，两种方法往往结合使用，先是诊断人员向驾驶员询问故障情况，对车辆进行直观检视，凭经验初步判断故障，再利用诊断仪器设备进一步筛选、识别，终确认故障。
In diagnosis practice, the two methods are often used in combination. First, the diagnostic personnel ask the driver about the fault, visually inspect the vehicle, preliminarily judge the fault based on experience, and then use diagnostic instruments and equipment to further screen, identify and finally confirm the fault.
The equipment fault analysis and prediction scheme based on relevant technologies shall be adopted, and the data diagnosis and analysis shall be used to analyze the rule of the fault, so as to quickly find the root cause of the fault, deal with the equipment fault and avoid the repeated occurrence of the fault.
