What problems can occur when a car passes over a large pothole?

Here are the possible situations after a car passes over a large pothole: 1. Tire and rim deformation: When a car is driving at high speed and suddenly passes over an uneven road surface, the wheels bear the maximum impact force. If the speed is too high, it can directly cause the tire to be scrapped, and in severe cases, it can even deform the rim. If you accidentally drive over a large pothole, be sure to check the wheel damage in time while ensuring safety. If there is shaking or abnormal noise, remember to call for roadside assistance promptly. 2. Suspension system damage: After passing over a large pothole, not only the wheels but also the suspension system can be affected. If there is no significant damage to the tires and rims after inspection, it means the impact force has been absorbed by the suspension. Long-term driving over potholes can cause considerable damage to the suspension and shock absorbers, so try to avoid potholes as much as possible. 3. Oil leakage or abnormal noise from the chassis: The protective measures at the bottom of the car are quite strong, as the engine chassis usually has protective plates, so there is generally no damage. However, if there is oil leakage or abnormal noise from the bottom, it must indicate a serious problem. 4. Exhaust pipe rupture: The exhaust pipe at the bottom of the car is very fragile, just an ordinary pipe. If it is hit, it will definitely crack or break. A ruptured exhaust pipe is easy to detect because the car's exhaust sound will become very loud after the pipe is damaged.

What is the validity period for passing the Driver's License Subject 1 exam?

According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," the validity period of the learning driving certificate is three years, but the expiration date must not exceed the upper age limit for application. Applicants must complete the Subject 2 and Subject 3 exams within the validity period. If the exams are not completed within the validity period, the passing scores of any previously completed subjects will be invalidated. Subject 1, also known as the Subject 1 theory exam or driver theory exam, is part of the motor vehicle driver's license assessment. The exam content includes theoretical driving basics, road safety laws and regulations, local regulations, and related knowledge. The exam format is computer-based, with a time limit of 45 minutes. Subject 1 consists of 100 single-choice and true/false questions, each worth 1 point. If 11 questions are answered incorrectly during the exam, the system will automatically submit the test and end the exam. Subject 1 exam content: Driver's license and motor vehicle management regulations; road traffic conditions and regulations; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 exam precautions: During the Subject 1 exam, students should pay attention to their attire—no slippers are allowed, and electronic devices and bags are prohibited in the exam room. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen, and store personal belongings in lockers before entering the exam room. Upon entering, the identity verification station will assign a seat. After finding your seat, begin the exam. Ensure the camera is aligned with you and adhere to exam discipline. If you fail the first attempt, a retake is available on the same day. If you fail again, you must pay to reschedule. After completion, queue to collect your score report and sign it. Failure to sign will render the result invalid. There is no limit to the number of times you can schedule the Subject 1 exam. Each subject exam can be taken once, with one retake allowed if you fail. If you do not take the retake or fail the retake, the exam process ends, and the applicant must reschedule. However, Subject 2 and Subject 3 exams allow only five attempts each, and the exams must be scheduled at least ten days apart. If you fail the Subject 3 safe driving knowledge test, the previously passed road driving skills test scores remain valid. The driver's license exam consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge exam; Subject 2 refers to the field driving skills exam; Subject 3 is divided into two parts: road driving skills and safe driving knowledge. The safe driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, the official term (as per the Ministry of Public Security Order No. 123) does not include "Subject 4."

What is the battery model for the 10th generation Civic key?

The battery model is CR2032. It is a lithium manganese dioxide battery, named according to the IEC standard. Among them: C- indicates a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode; R- indicates that the shape of the battery is cylindrical. If it is square, F is used instead; 20 indicates that the diameter of the battery is 20mm; 32 represents the height of the battery as 3.2mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity is around 200mAh. The CR2032 typically has a lifespan of 5 years. If the manufacturer's production level is not high or quality control is poor, its lifespan will be significantly shortened. Domestic first-tier brand batteries can generally guarantee this lifespan. If the usage environment is ideal (sealed, room temperature, free from moisture, etc.), its lifespan can be further extended to 8 years or even 10 years. The usage time of a vehicle remote key battery is closely related to the frequency of use. The more frequently it is used, the shorter the usage time will be. If the remote key battery runs out of power, the mechanical key can be used directly to open and start the vehicle. The batteries used in car remote keys are button batteries, mainly including models: CR2016, CR2025, CR2032, and CR2450. For the specific model used in each key, the owner can refer to the battery model in the user manual for replacement. Button-type CR2016 battery: The usage rate of car key remotes is very high, and it is almost one of the most common car remote batteries. The voltage of this battery is 3V. Generally, car key batteries are powered by 9V, so every time the battery is replaced, three batteries need to be changed. Examples include Guangben, Toyota, Volkswagen, Mazda, etc. CR2016 specifications: battery diameter is 20mm, thickness is 1.6mm. Button-type CR2025 battery: Its usage rate is much lower than that of CR2016. However, it is still used in some car keys. It is thicker than the 2016 model but has a relatively higher storage capacity. CR2025 specifications: battery diameter is 20mm, thickness is 2.5mm. This type of battery is also commonly used in audio remotes. Button battery CR2032: Its thickness is twice that of CR2016. The 3V-CR2032 lithium manganese battery belongs to the lithium-manganese dioxide structure. The positive electrode material is chemically very stable manganese dioxide, the negative electrode material is metallic lithium, and the electrolyte is a lithium battery. The main components of the electrolyte are ethylene glycol dimethyl ether, propylene carbonate, and lithium perchlorate. It is shaped like a button, hence the name button lithium battery or lithium manganese button battery. Button battery CR2450: Compared to the other three models, it is thicker and larger, with a diameter of 24.5mm and a height of 5.0mm. The rated current value of CR2450 is 0.2mA, mainly used in low-power electronic products. Generally, the battery can provide an output current of 0.001mA to 5mA, with a continuous output current of up to 15mA and a flash output current of up to 30mA, meeting the requirements of most small electronic products for light emission, sound production, and radio frequency output.

What does EPC on a car mean?

Possible reasons for the EPC light to illuminate include: The car's throttle is dirty and needs cleaning. A fault in the braking system, in which case the brake light may also not illuminate. Issues with fuel quality, which can trigger the EPC warning light. EPC (Electronic Power Control) stands for Electronic Power Control system. When a sensor malfunctions or detects an abnormal condition, the control system will take appropriate measures based on pre-set protocols. Common causes of the EPC light illuminating: Faults in the engine intake system, throttle issues, fuel system problems, Engine malfunctions, ECU control unit failures, or brake light faults. Solutions for EPC light illumination: Troubleshoot intake system issues, use compliant fuel, clean the throttle body, etc. Remove carbon buildup from relevant parts, perform cleaning, etc. Re-flash related data (this is done when other faults are resolved but the issue persists). Other faults cannot be ruled out; specific actions should be based on actual vehicle diagnostics before proceeding with repairs. What to do when the EPC light comes on: Restart the vehicle after turning it off and check the EPC light. If it doesn't illuminate again, there may be no issue—sometimes the EPC light can come on due to external interference. If the EPC light frequently illuminates over a period, first check if the brake light is on. If the brake light is off, inspect the brake switch, bulbs, and wiring (sometimes a faulty brake bulb can cause this; replacing the bulb may suffice). If the EPC light remains on after checking the brake light, take the car to a 4S shop for inspection. The EPC indicator usually appears in two colors: yellow or red. A yellow EPC light means the car can still be driven but should proceed slowly to a repair point. A red EPC light indicates a serious issue—pull over immediately and contact a technician. Continuing to drive could damage core components or compromise safety.

Do I need to handle an illegal parking notice?

An illegal parking notice must be handled, and this situation will result in a fine without deducting points. After receiving the illegal parking notice, the vehicle owner needs to personally go to the local traffic police station for processing, bringing their driver's license and vehicle registration certificate. Illegal parking requires accepting corresponding penalties, but in some cases, an appeal can be filed, such as to avoid an ambulance or if the vehicle breaks down. You can check whether you meet the conditions for an appeal, and if so, you can file one. The illegal parking notice must be processed within 15 days at the local traffic police station. If overdue, it may cause adverse effects.

How long can a dash cam save videos?

The video retention duration of a dash cam depends on its memory card capacity. A 16GB card can record approximately 100 minutes, a 32GB card around 200 minutes, and a 64GB card about 400 minutes. Dash cams typically record in a loop, automatically deleting the oldest footage when the memory is full. To preserve videos from a specific period, you need to disable loop recording, which allows permanent storage as long as the memory card remains undamaged. Since many accidents occur at night, the clarity of a dash cam's nighttime recording is crucial. Most dash cams come equipped with infrared capabilities or features like anti-backlight and anti-glare. When purchasing, make sure to inquire about these specific functions.
