In the modern automobile industry, car maintenance computer testers have become an indispensable and important tool in maintenance work. This high-tech equipment can quickly and accurately diagnose various vehicle problems and provide valuable technical support to maintenance personnel. So, as an ordinary car owner, do you know how to use a car maintenance computer tester to maintain your car? Today, we will discuss this topic together.
A car maintenance computer tester is a professional diagnostic equipment. By connecting to the car's diagnostic interface, it can read various fault information stored in the vehicle computer system and perform corresponding operations. analysis and diagnosis. It is widely used in vehicle maintenance of various engine types, and can help maintenance personnel quickly locate faults and improve maintenance efficiency.
Modern cars rely more and more on electronic control systems, and many faults are hidden in complex circuits and are difficult to detect. The car maintenance computer detector can scan the on-board computer system, extract and decode various fault codes, indicate the problem to the maintenance personnel, and provide a basis for targeted maintenance.
The main functions of the car maintenance computer tester include:
Read the fault code of the vehicle computer system and display the fault information to diagnose and test various electronic control systems, such as engines, Transmissions, braking systems, etc. display real-time vehicle working parameters, such as engine speed, load, temperature, etc. Perform maintenance operations such as system reset and parameter adjustment to save diagnostic data to facilitate the establishment and analysis of maintenance recordsTo use a car maintenance computer detector, you need to follow the following steps:
Connect the detector to the diagnostic interface of the vehicle through the diagnostic cable. Select the model and system according to the prompts, and perform a fault scan. The detector will display the fault code and related information. According to these Carry out fault diagnosis based on the diagnostic results and carry out targeted repairs based on the diagnosis results, and perform system reset or parameter adjustment through the detector. After completing the repair, use the detector again to confirm whether the fault has been eliminated. Using a car maintenance computer detector requires certain professional knowledge and operation. Skills, for ordinary car owners, they can check the instructions for use first, or entrust a professional repair shop to perform diagnosis and repair. Precautions for using the car maintenance computer testerYou need to pay attention to the following points when using the car maintenance computer tester:Ensure that the detector is correctly connected to the vehicle diagnostic interface. Operate carefully to prevent damage to the vehicle electronic system. Perform professional diagnosis based on fault information to avoid blind repairs. Pay attention to saving maintenance records to provide reference for the next maintenance. Calibrate the detector and upgrade software regularly
In short, Car maintenance computer tester is an indispensable tool in maintenance work. As a car owner, mastering how to use it will not only help you find and eliminate faults in time, but also protect your car and extend its service life. I hope this article is helpful to you, thank you for reading!
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.
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
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 connector 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 in 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.
Please note that different car fault detectors have different functions and operating interfaces, and the specific steps may be different.
