How to accurately query the vehicle factory configuration information
If you want to query the factory configuration information of the vehicle, you can query the relevant information of the vehicle through the frame number. You can consult the customer service of the manufacturer, or you can confirm it according to the model year through the configuration information of the manufacturer official website.
Frame number, also called VIN code, is also called vehicle identification number. Vehicle identification number (VIN), VIN is the abbreviation of English vehicle identification number. Because the ASE standard stipulates that the VIN code consists of 17-bit characters, it is commonly known as 17-bit code. Correctly interpreting the VIN code is very important for us to correctly identify the vehicle type and make correct diagnosis and maintenance.
Through the arrangement and combination of vehicle identification codes, vehicles of the same model will not have duplicate numbers within 30 years, so they can be called "car identification cards", and the history of frame numbers can be traced back to 1949 at the earliest. It should be noted that the frame number does not contain English letters O Q and I to distinguish 0 and 1 in Arabic numerals.
In the frame number of 17 letters and numbers, the tenth digit indicates the production year of the vehicle (the production year is 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f, g, h, j, k, and so on).
We can check the delivery time of the vehicle by the number of the frame number 10. The car code delivered by 20 19 is K. If the car code delivered by 2020 is L, the car code delivered by 202 1 is M, and so on.
How to adjust the lighting by yourself
Choose dim conditions, park the front of the car against the wall, turn on the headlights, cover the headlights with thick opaque cloth, and adjust each headlight separately. In order to ensure that the headlight beam is in the normal driving place, it is best not to leave the car empty.
Specific steps: 1. Choose a dark situation, such as in the underground parking lot or at night, you can park the front of the car against the wall, and try to align the front of the car with the wall at a distance of about 5 or 6 meters.
2. Turn on the headlights, cover them with thick opaque cloth, and adjust each headlight separately. In order to ensure that the beam position of headlights is in the normal driving place, it is best not to leave the car empty and let friends sit in the driver's seat.
3. You can make a mark in the center of the lighting range of the lamp wall with a marker pen or chalk, and at the same time make a mark corresponding to the logo on the wall.
4. Adjust the height of the low beam. The right light should be completely horizontal and direct, and the left light should be raised about 10cm, but the adjustment should not be too high to prevent the light from directly hitting the eyes of the driver of the opposite car. The irradiation range of the right light can also be shifted to the right, which can improve the visibility of the right side of the next car.
