Who can help me explain the meaning of vehicle model and vehicle identification number in detail?

CAF7202AC3 is the vehicle model, the first two or three letters represent the manufacturer, CA is FAW, SGM is SAIC-GM, QR is Chery and so on. The last four digits represent the vehicle model, the first digit represents the purpose, 1 represents the truck, 2 represents the off-road vehicle, 3 represents the dump truck, 4 represents the tractor, 5 represents the special vehicle, 6 represents the bus, 7 represents the car and 8 represents the semi-trailer. The middle two digits have two meanings, which may refer to the displacement or the length of the car body, which is determined by the manufacturer. The last digit represents the difference code of the same platform, the same type and different models, and the additional code behind it specifically distinguishes different models!

The long number behind is the vehicle identification number (VIN), which is the abbreviation of English vehicle identification number. Because SAE standard stipulates that the VIN code consists of 17 characters, it is commonly known as 17-bit code. It includes the manufacturer, year, model, body type and code, engine code and assembly position of the vehicle. Correct interpretation of VIN code is very important for us to correctly identify vehicle types, make correct diagnosis and maintenance.

In order to help you understand the VIN code, let's briefly introduce the related knowledge of VIN.

I. Definition of terms

Three. World Manufacturer Identification Number (WMI)

According to the geographical area, WMI codes are assigned to each vehicle manufacturer. The code consists of three-digit codes and contains the following information:

-The first code is alphanumeric, indicating geographical regions, such as Africa, Asia, Europe, Oceania, North America and South America.

-The second code is a letter or number, indicating the country in a specific region. In the United States, the Society of Automotive Engineers (SAE) is responsible for assigning country codes.

-The third code is a letter or number indicating a specific manufacturer, which is assigned by authorized agencies in various countries.

When the annual output of the factory is less than 500 vehicles, the third word of the world factory identification code is 9.

Four. Location of vehicle type license plate (including VIN):

-Except for trailers and motorcycles, the signboard shall be fixed on the door hinge pillar, door lock pillar or one of the door edges engaged with the door lock pillar, close to the driver's seat; If there is no available position, fix it on the left side of the instrument panel. If it doesn't work there, fix it on the inside of the door near the driver's seat. If none of the above positions can be used, a written application should be submitted to NHTSA.

-The location of the signboard shall be in a place that is easy to read without moving any parts of the vehicle (except the outer door).

According to the above explanation, when you see the VIN of1g1B52P7TR1kloc-0/5520, the information you can immediately understand is: 1996, GM (or Suzuki), origin: the United States.
