Ten major items of comprehensive detection of car maintenance knowledge

1. Brakes should be sensitive. For cars with long self-driving time, the brake system is prone to problems. In some car repair shops, there are long queues for cars to check the braking system.

2. Maintenance is better than repair. 10 items of car maintenance. Cars need "three parts repair, seven parts maintenance", that is, through active inspection and maintenance, to find and eliminate some early, potential and implicit faults. Especially in the cold winter after the sudden drop in temperature, the maintenance of your car is very important.

3. If there is any abnormality in gear shifting or vibration, gear jump, etc., check the transmission oil in time. 1 Brake pads There is no unified concept of replacing brake pads, especially for car owners who like to drive on the brake or use the brake frequently, they should often observe the brake pads.

What knowledge does the professional maintenance and inspection of automobiles include?

The following are some basic knowledge that needs to be mastered for automobile inspection and maintenance: Engine: Understand the structure, working principle and troubleshooting methods of the engine, and master the methods of replacing and adjusting engine parts. Transmission system: Understand the structure, working principle and fault diagnosis method of the transmission system, and master the method of replacing and adjusting the parts of the transmission system.

Automobile repair and maintenance: Students will learn the techniques and methods of automobile repair and maintenance, including the disassembly, replacement and debugging of automobile mechanical parts and electrical parts. They will understand the basic requirements and safety operation specifications of automobile maintenance operations, and be familiar with the maintenance processes and methods of common faults.

If the body and steering wheel shake at this time, and the car does not shake, the reason for the vibration is that the front axle of the car is faulty; check whether the positioning angle and front beam of the front wheel meet the requirements, and adjust if they are not aligned; set up the front axle to test the wheel, check the wheel dynamic balance, and whether the tire is too deformed.

Automotive comfort and safety system overhaul, automobile comprehensive fault diagnosis and exclusion, automobile sheet metal and spraying, automobile new energy technology, automobile insurance and claims settlement and other courses.Graduates are employed in automobile 4S stores and related industry enterprises, engaged in automobile mechanical and electrical maintenance, whole vehicle or accessories sales, insurance company vehicle damage determination, etc.

How to use the automobile maintenance computer detector

What is the usage of the automobile fault diagnostic instrument? Open the on-board OBD interface, insert the automobile fault diagnosis instrument into the on-board OBD interface, and connect it according to the instructions. Turn off the accessories. Turn on the power supply, start the car fault diagnosis instrument, enter the operation interface of the car diagnosis instrument, and select the car diagnosis module.

The first step to using a car maintenance computer detector is to connect it to the diagnostic interface of the car, which is usually located under the dashboard near the driver's seat of the vehicle. After starting the car, turn on the power of the detector, and then select the corresponding car brand and model according to the operation prompts on the instrument.

Plug the plug into the obd interface of the car. Press the one-button start button of the car to turn on the power. Click the same icon as the car brand. Click to confirm in the lower right corner. Choose the first 16-pin option. Click Automatic Search, and the system will find the model of the vehicle.

Note: Connect the connector first, then turn on the ignition switch to ON gear, and finally turn on the car fault diagnostic instrument. The above usage method is relatively basic, and the usage methods of different automobile fault diagnostic instruments will be different. The specific operation can be used according to the instruction manual of the automobile fault diagnostic instrument.

The current car computer detectors are basically in Chinese, so it feels like a small computer. Just look at the screen step by step and find what you need to do.

NoteWhether the instrument pointer of the car inspection and maintenance equipment stays in the initial position. If it is not in the standard position, it should be adjusted in time. Calibrate and adjust the automobile inspection equipment in strict accordance with laws and regulations. If there is any damage or failure, it should be dealt with in time.

What is the car maintenance process and main content

Car maintenance service generally includes the following processes: fault inspection and diagnosis: When the owner brings the vehicle to the repair shop, the technician will check the vehicle Parts and systems to confirm the source of the fault and the repair measures that need to be taken.

What do you need to do for car maintenance? Introduction to automobile maintenance projects: oil change: oil mainly has the functions of lubrication, anti-corrosion, cleaning, cooling and buffering.Lubrication: The oil forms an oil film on the surface of each part, which can achieve the effect of lubricating the parts, while isolating the parts from the air to prevent the parts from being corroded.

And the brake coolant lubricates the internal performance of the brake. It is recommended to replace it once after driving 30,000 kilometers. Finally, it is recommended to clean up the carbon of the engine every 50,000 kilometers, and that's all the car maintenance items. By talking about the topic of automobile maintenance projects, we can see that automobile maintenance projects and processes are actually relatively simple.

The repair and maintenance of cars is a systematic process that needs to be carried out according to certain steps to ensure the safety, reliability and service life of the car. The main contents of car maintenance include appearance inspection, engine inspection, tire inspection, braking system inspection and exhaust system inspection.

The process of automobile maintenance service can be roughly divided into six steps: appointment service, reception, maintenance operation, quality inspection, checkout and delivery and tracking service, and each step has corresponding service standards and specifications. Some maintenance enterprises will be more refined and subdivide one of the steps into two or more steps.
