6. How to use the car computer tester? Use car computer tester?

Methods to use:

1. First determine the car series to be diagnosed, and then select the corresponding car fault diagnosis instrument plug. Different car models correspond to different plugs. Most of them on the market are OBD2 and OBD2 plugs with CAN. 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.

7. What are the advantages and disadvantages of automobile fault detectors?

It can detect car faults easily and straightforwardly, saving maintenance personnel time and reducing trouble. Of course it's nice and modern. However, it also has limitations, such as some faults that it cannot detect. What it can detect are basically the most important components, such as insufficient engine oil pressure, no high-pressure fire, ignition timing problems, etc. These faults have been entered into the computer program.

But it cannot detect many car faults

8. How to use the car fault detector?

Using a car fault detector (OBD-II scanner) can help you diagnose vehicle faults and obtain relevant fault codes. The following are the basic steps for using a car fault detector:

1. Preparation: Make sure the vehicle's ignition switch is turned off. Locate the vehicle's OBD-II interface, usually located on the dashboard under the driver's seat. You can check your vehicle's owner's manual or search the Internet for the location of the port for your specific model.

2. Connect the scanner: Plug the OBD-II scanner’s connection cable into the vehicle’s OBD-II interface. Make sure the connection is secure.

3. Turn on the vehicle power: Turn on the vehicle's ignition switch, but do not start the engine. Some scanners require vehicle power supply to function properly.

4. Operate the scanner: Perform relevant settings and operations according to the scanner's instructions. Most scanners have user-friendly menus and interfaces, and you can use the arrow keys and confirmation keys to navigate menus, select functions, and execute commands.

5. Diagnose vehicle faults: Select "Diagnosis" or a similar option, and the scanner will start communicating with the vehicle's computer and read relevant fault codes. These DTCs are problem-specific codes stored by the vehicle's computer that can help you determine what's wrong with your vehicle.

6. View fault codes: The scanner will display a list of fault codes. You can consult your scanner's manual or use an Internet search to decipher what the trouble code means. DTCs may involve different systems and components of the vehicle, such as the engine, transmission, brakes, etc.

7. Clear fault codes (optional): If you want to clear the fault codes that have been read, you can select the corresponding option to clear them. Please note that clearing a fault code does not mean that the problem with the vehicle has been fixed, and the fault code may reoccur until the problem is resolved.

8. Analysis and repair: Analyze vehicle problems based on the read fault codes and related information, and take appropriate repair measures. If you're not sure how to fix the problem, it's recommended to consult a professional auto technician or take your vehicle to a professional repair shop for diagnosis and repair.

請注意，不同的汽車故障檢測儀具有不同的功能和操作介面，具體步驟可能會有所不同。

十、汽車故障偵測器可靠嗎？

汽車診斷儀的作用

首先我們需要知道汽車診斷儀有什麼功能，分別有讀取故障碼、清除故障碼、讀取引擎動態資料流、示波功能、元件動作測試和匹配、設定和編碼等功能。

汽車故障診斷儀就是通過以上的功能，選擇需要檢測的車型後，對該車型的各部件進行檢測。讀取出汽車在靜止、啟動時的故障數據，再進行對應的系統模組及零件維修。

因為每車型的各系統工況的數據，本來已經記錄在汽車診斷儀裡面，所以根據讀取汽車目前的故障狀態。就可以判斷汽車的故障，大概在什麼系統，或是哪個零件有問題。

幾十塊汽車故障儀有用嗎

一般作用不是很大，但如果不是用來進行維修車輛的，只能用來做汽車的日常保養，可以正常的使用。如果需要對汽車各系統的資料進行檢測的話，幾十塊汽車故障儀應該是沒有什麼作用的。因為目前專業的故障診斷器也需要2000元，或是上萬元的價格。

所以，價格不是衡量故障診斷儀有沒有用的標準，需要看使用故障診斷儀檢測什麼項目決定的。
