Where is the VIN located on a Haval H2?

The VIN (Vehicle Identification Number) of a Haval H2 is located at the lower left corner of the windshield and under the front passenger seat. Under the passenger seat, there is a Velcro strip with two staples on both sides; lifting it will reveal the VIN. Additionally, the VIN can also be found on the engine, insurance policy, and vehicle registration documents. To locate the VIN on the engine, you need to either use a pit or a car lift to raise the vehicle and inspect it from underneath. Vehicle Identification Number (VIN): A VIN is a unique 17-character code composed of letters and numbers used to identify a vehicle. It provides information about the manufacturer, model, chassis number, and other characteristics. To avoid confusion with the numbers 1 and 0, the letters "I," "O," and "Q" are not used. The first three characters of the VIN represent the manufacturer's information, known as the World Manufacturer Identifier (WMI). Characters 4 to 8 indicate vehicle characteristics such as model, engine, transmission, and braking system, which vary by manufacturer. The 9th character is a check digit used to verify the accuracy of the VIN. The 10th character represents the vehicle's production year, the 11th character indicates the assembly plant, and characters 12 to 17 denote the production sequence number. Uses of a vehicle's VIN: Checking the production year: Many vehicle models are recalled due to defects. By checking the VIN, you can determine whether your vehicle or a vehicle you intend to purchase is part of a recall batch. Identifying genuine imported vehicles: The first character of the VIN indicates the country of manufacture. If it is "L," the vehicle is domestically produced; otherwise, it is imported. Checking vehicle history: By querying the VIN, you can obtain detailed information about the vehicle's maintenance records, including whether it has been involved in accidents, floods, or fires.

What Are the Reasons for Poor Cooling in Large Vehicle Air Conditioning?

The main reasons for poor cooling in large vehicle air conditioning are: 1. Too much or too little refrigerant: In the air conditioning system, the proportion of refrigerant has specific requirements. Too much or too little can affect the cooling performance. If there is too little refrigerant, the amount sprayed into the evaporator by the expansion valve decreases, leading to reduced cooling capacity. Conversely, too much refrigerant can affect heat dissipation, as more heat dissipation results in greater cooling capacity. 2. Clogged filter: Vehicle air conditioners are equipped with air filters to block impurities. If not cleaned or replaced for a long time, accumulated impurities can clog the filter, preventing cold air from flowing out and reducing cooling efficiency. 3. Compressor damage or aging: The air conditioning compressor is a crucial component for normal operation. If the vehicle is older and the air conditioning fails to cool, the compressor may have issues like looseness or aging, affecting transmission efficiency and leading to poor cooling. First, check if the drive belt is broken, then listen for noise inside the compressor. 4. Damage to the air conditioning compressor, throttle valve, or expansion valve: The likelihood of compressor damage is low, so it’s not a major concern. However, faults in the expansion valve or throttle valve directly cause poor air conditioning performance. These checks are complex and require professional repair services.

What is the tutorial for replacing the wiper of Changan CS35?

Changan CS35 wiper replacement tutorial: 1. First, fully lift the wiper. To avoid damaging the windshield during the removal and installation process, it is recommended to place a cloth on the windshield when removing or installing the wiper, and adjust the blade angle by propping up the wiper. 2. Change the angle of the wiper blade, preferably making it at a 90-degree angle to the wiper arm. Since the entire wiper blade is secured to the arm with a clip, this angle facilitates easier removal and installation. 3. Once positioned at the correct angle, you can begin the removal process. First, use one hand to lift the rubber blade to expose the fixing hook between the wiper arm and the blade. Then, remove the entire wiper blade. Next, use one hand to horizontally pry open the rubber blade while the other hand presses down firmly on the main bracket to separate the wiper blade from the arm. After this, the entire wiper blade can be removed. In terms of body dimensions, the Changan CS35 measures 4170mm in length, 1810mm in width, 1670mm in height, and has a wheelbase of 2560mm.

What does AUX on the audio system mean?

AUX is an audio input interface. The basic working principle of the AUX interface is that after connecting to the AUX interface, the audio from electronic devices can be transmitted through the headphone jack and AUX interface to the car audio system, allowing playback through the car audio broadcasting facilities. The USB interface can be used to insert a USB drive for audio playback. To use it, connect one end to the AUX interface and the other end to a video player such as a mobile phone, MP3, or MP4. This allows you to listen to songs or niche music anytime, anywhere, without being limited to car music CDs. However, if the playback device runs out of battery, the music will stop (the interface is typically a 3.5mm standard headphone jack). Aux is the abbreviation for Auxiliary, which refers to an additional signal line design. On general audio equipment, besides the standard output and input terminals, there are often several terminals labeled Aux, serving as backup connection points. These can be used for special applications, such as additional audio output or input. Such backup terminals or lines, whether for input or output, are collectively referred to as Aux. Function: The AUX port is an asynchronous port primarily used for remote configuration, dial-up connections, or connecting to a MODEM via a transceiver. It supports hardware flow control. The AUX port and CONSOLE port are usually placed together because they are used in different configuration environments. The AUX interface establishes a command-line connection between the user and the device, enabling operations that are typically not possible in user mode, such as initialization, restoring default configurations, or correcting abnormal user modes. It provides a fixed port for the device, which can be used as a standard asynchronous serial port with a maximum speed of 115200bit/s. Using the AUX interface, functions like remote configuration and line backup for hardware products can be achieved. Note: When using the AUX interface, ensure you purchase the correct connecting cable and avoid plugging the audio cable into the wrong port. It's best to follow the steps outlined in the product's user manual. If unsure, consult the product's official website or call for assistance.

What does the traffic violation code 1225 mean?

The violation code 1225 means: Engaging in other behaviors that hinder driving safety while operating a vehicle. According to the relevant provisions of the "Road Traffic Safety Law of the People's Republic of China", the penalty includes: Demerit points (deduction): 2 points; Fine amount: 100 yuan; Other penalties: None. Traffic violation codes consist of four to five digits, classified according to the principles of the traffic law. The sequence from left to right is: the first digit represents the behavior classification code, the second digit represents the demerit point classification code, the third and fourth digits are sequential numbers, and the fifth digit indicates the specific item number. First digit: Behavior classification code, indicating the category in the Road Traffic Law; Second digit: Demerit point classification code, indicating the category of demerit points for the traffic violation; Third, fourth, and fifth digits: Sequential code, indicating the order of the violation within the same behavior category. For example: 13035—"1" indicates a motor vehicle behavior, the second digit "3" indicates a 3-point deduction, and "035" indicates the fifth item of the third violation in the 3-point deduction category. Behavior classification code explanation: Codes starting with 1 indicate motor vehicle violations, e.g., 1003; Codes starting with 2 indicate non-motor vehicle violations, e.g., 2002; Codes starting with 3 indicate pedestrian or passenger violations, e.g., 3030; Codes starting with 4 indicate highway violations, e.g., 4002; Codes starting with 5 indicate other regulations, e.g., 5005; Codes starting with 7 indicate provincial, autonomous region, or municipal implementation rules, e.g., 7008; Codes starting with 8 indicate local regulations of cities (regions, autonomous prefectures, leagues), e.g., 8606. There are four common methods to check motor vehicle violations: Visit the office halls of traffic branches in various districts and counties to inquire through touch-screen terminals; Log in to the external service websites of the public security traffic management bureaus of various cities, locate the vehicle violation inquiry section, enter the license plate number and engine number, and click to inquire; Call the inquiry hotline (area code + 114); Use the Traffic Management 12123 app (V2.8.1B437 for iOS 15+ or V2.8.1B274 for Android 12+) to inquire. Violations involving behaviors that hinder driving safety while operating a vehicle can be processed through the Traffic Management 12123 app. After logging in, enter the violation processing business flow, complete the process, and make the payment.
