汽车故障电脑诊断仪中的通道号是诊断特定系统或组件时使用的关键参数。它表示诊断仪与车辆电子控制单元（ECU）之间的特定通信线路。不同的车辆和系统具有不同的通道号，用于访问不同的信息或执行特定命令。了解通道号对于准确诊断故障并确保诊断仪与车辆的正确通信至关重要。本文将深入探讨通道号的概念，解释其重要性，并指导您如何确定特定车辆和系统的正确通道号。
汽车故障电脑诊断仪中的通道号是指一个系统的地址代码，用于在诊断仪与汽车电子控制单元（ECU）之间建立通信连接。通道号是用于识别不同系统的地址代码，以便在多个系统之间进行通信和诊断。
通过输入通道号，诊断仪可以与特定的ECU建立通信，并获取相关的故障信息、参数数据和系统状态。不同的车型和制造商可能使用不同的通道号，因此在使用诊断仪时需要查阅汽车制造商提供的文档或使用诊断仪附带的数据库来查找正确的通道号。
通道号在汽车维修和检测中非常重要，因为它们可以帮助技术人员快速准确地识别和解决汽车故障，提高维修效率和质量。
需要多方面了解。目前汽车故障电脑诊断仪品牌很多，而所测车型全面，升级方便，售后服务好，性价比最高有博世 和 元征两家。 博世的设备偏贵，元征的X-431系列较实惠。
一、评价汽车故障诊断仪的优劣，需要看哪些方面呢？
您在提这个问题时候或许自己已经有一部分答案了！ 汽车诊断仪的优劣可以从很多方面来评价，软件诊断功能的深度、覆盖车型的广度、硬件的稳定性、设备的可扩展性、采购价格、售后便利性等。 最适合您自己的，就应该是很优秀的。
1、通常4S站里面使用的原厂诊断仪，从诊断软件功能方面来说肯定是很优秀的，硬件也比较不错；但价格不太美丽。
2、市面上有流通的类似原厂诊断设备的 专用仪器，诊断软件功能近似原厂诊断仪，价格相对亲民；如果抛开知识产权或法律方面的考虑，这个对需求者来说是比较有优势的。
3、公开市场正常流通的第三方诊断仪，如：元征、道通、朗仁、欧克勒亚、富士伟业、博世、红盒子、星卡、小欧....； 车型覆盖较为广泛、诊断软件深度次于专用设备、硬件平台有不同型号、价格区间清晰，总有一款适合您。
二、结合当前售后维修行业现状，诊断仪的应用场景及使用人员的自身技术能力，以及投资回报比等， 可以将设备大致分为：常规诊断、带编程功能诊断、带远程诊断等这几个档次。
常规诊断：读故障、清故障、数据流、动作测试、保养匹配编码等特殊功能，当前价格常在4千左右区间。市面几大主流品牌都有对应区间的型号产品。
带编程功能诊断：覆盖上面第一项的功能，另外可以支持作在线编程，这里的编程是指汽车电控模块中的底层运行软件安装（不是指计算机语言编程），因覆盖的可编程车型数量不同，当前价格常在6-8千左右区间。市面几大主流品牌几乎都有对应区间的型号产品。
带远程诊断功能：通常是覆盖上面第二项的功能，另外可以支持远程诊断；即通过C端（通常与诊断模块集成在一起）通信模块将远端更专业的诊断设备的功能延伸到本地车辆，这是“物联网+ ”技术的深度应用，搭载车辆诊断技术实现远程异地诊断。当前价格常在8-10 千左右区间。市面几大主流品牌有对应区间的型号产品。
三、汽车故障诊断仪就硬件本身是电子产品，根据当前是电子产品的特性即发展状况，诊断仪的使用寿命可以规划预期为42个月，即三年半；设定42个月后硬件性能大幅度下降或故障率升高，维修成本增加；该设备报废残值参照15%-20%。
通过以上几方面信息，相信您应该有更加明确的选择了； 欢迎价关注探讨~！
Car computer tester is an important tool for diagnosing vehicle faults. The price varies depending on the brand, function and model. The difference. Generally speaking, the price of an ordinary car computer tester ranges from 500 yuan to 2,000 yuan, while the price of high-end professional models may be higher.
The car computer detector can read the vehicle's fault code, real-time data, vehicle speed, rotational speed and other information by connecting to the vehicle's OBD interface, helping car owners or repairmen accurately locate vehicle faults.
When choosing a car computer tester, you need to consider the following points:
Compatibility: Make sure the selected tester is compatible with your car model. Features: Choose the right features and performance based on your personal needs. Ease of use: Choose products that are easy to operate and have a user-friendly interface. After-sales service: Choose brands and channels with good after-sales service.When using the car computer detector, you first need to find the OBD interface of the vehicle, and then connect the detector according to the instructions for fault diagnosis and data reading. During the operation, you need to read the instructions carefully and operate correctly according to the instructions to avoid misoperation.
Through the understanding of the above content, I hope it can help everyone have a clearer understanding of automotive computer testers and become more comfortable when purchasing and using them.
Thank you for reading this article, I hope it helps!
1. First, find a fault diagnosis instrument and the faulty vehicle.
2. Then connect the diagnostic tool interface to the car. As for the car, it is generally set under the steering wheel, at the driver's knee position. Find and connect it.
3. Wuling vehicles are generally installed under the co-pilot’s seat.
4. Turn the ignition key to the ON position, then turn on the diagnostic tool. Select car diagnosis on the page, then select the corresponding car model and click on the engine model.
5. Select the engine system, choose to read the fault code, then return, choose to clear the fault code, start the engine and then read the fault code.
6. If the check fails, you can choose to read the data stream, check the data changes, and then compare it with the maintenance book. This is the basic use of the diagnostic tool.
The fault diagnosis instrument is responsible for checking car faults and outputting error codes. The decoder is used to read the diagnosis results and output understandable Chinese characters. Let’s explain it this way: the diagnostic tool is the doctor, and he writes out medication orders, but no one knows the doctor’s name. The decoder is the person who takes the medicine, and can only understand what the doctor writes. Vehicle fault self-checking terminal and car fault diagnosis instrument (also known as car decoder) are portable intelligent car fault self-checking instruments used to detect car faults. Users can use it to quickly read faults in the car's electronic control system and pass The LCD screen displays fault information, and the location and cause of the fault can be quickly identified.

But it is not the first company in China to integrate R&D, production, sales and after-sales of automotive fault detection equipment and driving computer systems. It is also a supplier of R&D solutions for automotive electronic products.
There are many brands and models of car fault diagnostic instruments on the market. Which one is better depends mainly on the following aspects:
1. Applicability: Different car brands and models require different diagnostic instruments, so before purchasing You need to confirm whether the selected product is compatible with your vehicle before purchasing.
2. Function: Different diagnostic instruments have different functions. Some are only able to read vehicle fault codes, while others can detect more vehicle data and provide richer fault solutions. Therefore, you need to choose the corresponding functions according to your own needs.
3. Brand and after-sales service: Choosing a diagnostic instrument from a well-known brand will be more reliable and reassuring in terms of equipment quality, stability and after-sales service.
Common automotive fault diagnosis instrument brands include Launch, Autel, Bosch, Foxwell, Actron, etc. Their product quality and after-sales service are guaranteed, and users can choose according to their own needs. At the same time, you need to pay attention to issues such as price, ease of use, and difficulty in upgrading before purchasing.
Nowadays, the most mainstream brands in the automotive fault diagnosis instrument market include Launch, Langren, Bosch, etc. Each has its own characteristics. For example, Launch’s is more common, but has few special functions. Langren’s diagnosis The functions are ordinary, but the special functions such as key matching, meter adjustment, maintenance reset, and throttle matching are the most common, and the service of the technicians is good.
If you open your own repair shop, it is recommended to choose Langren’s PS90, because there are many projects that can be done, and you can make more money by doing one more.
How to use the car computer diagnostic tool:
1. First determine the car series to be diagnosed, and then select the corresponding car fault diagnostic tool plug. Different car models correspond to different plugs. Most of them on the market are OBD2 and CAN. OBD2 plug. Plug the plug into the corresponding diagnostic interface of the vehicle (mostly on the left and right sides under the steering wheel).
2. Turn the ignition switch to the ON position, then turn on the diagnostic tool, select the corresponding car model for car diagnosis, and select the corresponding engine model.
3. Select the engine system and read the fault code. It can be seen that the car currently has some fault information. If the fault code cannot be checked, you can choose to read the data stream, check the data changes and then compare it with the maintenance book.
4. Clear the fault code after diagnosis and repair, start the engine and read the fault code again to see if it has been cleared.
