What information is required for the annual inspection of the automobile

The vehicle driving license is one of the important materials for the annual inspection of the vehicle. The driving certificate contains the basic information of the vehicle, including the model, brand, frame number and other letters If the information on the driving license is inconsistent with the actual situation of the vehicle, the vehicle will not be able to pass the annual inspection.

The materials to be prepared for the annual inspection of the car are as follows: the original and photocopy of the owner's ID card. The original and photocopy of the motor vehicle driving license. Traffic insurance policy (within the validity period, including vehicle and ship tax).

Information required for annual automobile inspection: the original (copy) of the compulsory insurance certificate for motor vehicle traffic accidents; the safety and technical inspection certificate (provided by the automobile inspection station); the original motor vehicle driver's license; the vehicle and ship tax payment certificate; the original ID card of the car owner (the agent also needs the agent's ID card).

The annual inspection of the car requires the original driving license, a copy of the traffic insurance, and a copy of the ID card. The annual inspection of the automobile refers to a necessary test for every vehicle that has obtained an official license plate and driving license, which is equivalent to a physical examination of the vehicle once a year in accordance with the Technical Conditions for the Safety of Motor Vehicle Operation.

What information is needed for the annual inspection of cars?"Application Form for Motor Vehicle Inspection Pass Mark" (no need to carry, provided on the spot, fill in directly); motor vehicle driver's license; traffic insurance certificate; vehicle and ship tax payment or tax exemption certificate (generally purchased together with forced insurance, you can find this item in the forced insurance policy.

What are the commonly used automobile detection and diagnosis methods?

Instrumentation and equipment diagnosis method: The instrument and equipment diagnosis method obtains the information parameters of automobile performance and faults through instruments and equipment without disassembling automobile components, and compares them with the normal technical condition of automobiles to draw diagnostic conclusions of technical performance and faults.

The common diagnostic content of automobile diagnosis is to check whether the engine, the bottom of the car, the electric system, the steering device and various pedal mechanisms are normal;Whether the height of each liquid level is appropriate; whether there is oil leakage, water leakage, air leakage, electricity leakage and other phenomena. This kind of examination is basically measured by eyes.

The fault diagnosis of the technical condition of automobiles is completed through a series of activities such as inspection, measurement, analysis and judgment. The basic methods are mainly divided into two types: intuitive diagnosis and modern instrument and equipment diagnosis.

Test method: The test method is one of the common methods for diagnosing automobile and engine failures. The test method can check the function of the car and engine without disintegration or less disintegration, so as to achieve the purpose of fault diagnosis.

Precision detection and diagnosis: From the early 1980s to the early 1990s, due to the increasing degree of electronicization of automobiles, dynamic random faults and functional faults of control systems increased.

Basically, there are 12 methods of automobile fault diagnosis: consultation, observation, hearing, experiment, touch, smell, replacement, instrumentation, measurement, segmented inspection, and partial disassembly. All fault diagnosis methods are complementary, and the purpose is to find out the fault of the car.

What are the specific contents of car testing?

Car safety inspection Check whether the license plate of the vehicle and driving license are damaged, altered, unclear handwriting, etc. Check whether the vehicle has been modified, modified and replaced. Check whether the appearance of the vehicle is intact, whether the connectors are firm, and whether there are four leaks.

Hello, dear, vehicle inspection usually includes the following inspections: engine system: check the state of the engine, sensors, spark plugs, etc. to ensure the normal operation of the engine.Chassis system: Check the chassis system of the vehicle, including suspension, braking, steering and tires, to ensure its normal operation and safety.

Comprehensive performance testing of automobiles includes: automobile safety (braking, side slip, steering, headlights, etc.). Reliability (abnormal sound, wear, deformation, cracks, etc.). Dynamic (speed, acceleration capacity, chassis output power, engine power, torque, supply system, ignition system condition, etc.).
