What Causes the ABS and EPS Lights to Illuminate?

ABS and EPS lights may illuminate due to faults in components such as wheel speed sensors, ABS wiring, ABS pump, pressure modulation solenoid valves, or the ABS control module. How ABS Works: During braking, the ABS system rapidly determines wheel lock-up status based on speed signals from each wheel speed sensor. It then closes the normally open inlet valve for the locking wheel to maintain braking force. If the wheel continues to lock, the normally closed outlet valve opens, allowing brake fluid to return directly to the reservoir through the pipeline, rapidly reducing braking pressure on that wheel to prevent complete lock-up. This keeps braking at the optimal point (20% slip ratio S), achieving maximum braking effectiveness and driving safety. Functions of ABS: 1. Maximizes brake effectiveness, reducing braking time and distance. 2. Effectively prevents vehicle skidding and fishtailing during emergency braking, ensuring good driving stability. 3. Allows steering during emergency braking, maintaining good steering control. 4. Avoids severe friction between tires and road surface, reducing tire wear.

How Long Does a Car Compressor Last?

Car air conditioning compressors typically have the same warranty period as the vehicle body warranty, which is generally three years or 100,000 kilometers. If the compressor experiences quality issues within the warranty period, it can be repaired or replaced. Below is additional information: Introduction: The air conditioning compressor plays a role in compressing and driving the refrigerant within the air conditioning refrigerant circuit. The compressor is usually installed in the outdoor unit. It extracts refrigerant from the low-pressure area, compresses it, and sends it to the high-pressure area for cooling and condensation. Heat is dissipated into the air through the radiator, and the refrigerant changes from a gaseous to a liquid state, with increased pressure. Working Circuit: The working circuit of the air conditioning compressor is divided into the evaporation zone (low-pressure area) and the condensation zone (high-pressure area). The indoor and outdoor units of the air conditioner belong to the low-pressure or high-pressure area, respectively (depending on the operating state). The refrigerant then flows from the high-pressure area to the low-pressure area, where it is sprayed into the evaporator through the capillary tube. The pressure drops sharply, and the liquid refrigerant immediately turns into a gaseous state, absorbing a large amount of heat from the air through the radiator.

Should You Use Internal or External Air Circulation on Rainy Days?

On rainy days, it is recommended to use the external air circulation in your car. Cold weather during rain can cause fogging on both side windows, obstructing the driver's view. Therefore, it is best to first use the external air circulation and adjust the airflow direction towards the windshield. Using external circulation helps expel the moisture exhaled by passengers from the vehicle, while the outside cold air is less prone to condensation. Important Notes: Note 1: When the outside air quality is poor or heavily polluted, such as on dusty roads, in congested traffic, or near chemical plants where there are unpleasant odors or fumes, use internal circulation to prevent the poor outside air from entering the car. Note 2: In summer, to quickly cool down the interior with air conditioning, you can use internal circulation. Note 3: In winter, using internal circulation can help keep the interior warmer.

Can I Transfer to Another Driving School?

Driving schools do not allow transfers because motor vehicle driver training operates on a credit hour system, with fees reasonably charged based on the hours completed. Below are the relevant requirements and regulations for motor vehicle driver training: Pre-service Training: Motor vehicle driver training institutions must provide instructors with pre-service training covering road traffic safety laws and regulations, safe and civilized driving knowledge, teaching abilities, etc. Pre-service training must be no less than 36 credit hours. Off-the-job Training: Strengthen the professional ethics education of instructors and provide continuing education on new driving knowledge and technologies. Instructors must undergo at least 12 credit hours of off-the-job continuing education per year to enhance their professional quality. Supervision and Inspection: Motor vehicle driver training institutions should strengthen the supervision and inspection of instructors' teaching conditions, regularly evaluate instructors' teaching levels, teaching performance, and professional ethics, publish rankings of instructors' teaching quality, and urge instructors to improve teaching quality.

How many points will be deducted for overloading 2 people in a 5-seater car?

A 5-seater car overloaded with 2 people is considered to exceed 20% of the capacity, resulting in 3 penalty points and a fine. For non-commercial small passenger vehicles, exceeding the approved passenger capacity by less than 20% results in 2 penalty points and a fine, while exceeding 20% or more results in 3 penalty points and a fine. Below are the hazards of overloading: Shortens the vehicle's lifespan and accelerates component aging: Overloading alters the original design specifications. For example, it can cause rivets to loosen, fastening screws to fall off, welding points to break, and the overall frame to deform. Overloading reduces the vehicle's lifespan and accelerates the aging of rubber and plastic components. Accelerates tire wear and deformation: Car tires are designed and manufactured based on the vehicle's total weight, with a considerable safety margin. However, when the vehicle is overloaded, the tires bear excessive weight and deform. Increased friction also shortens tire lifespan. Tests show that overloading by 20% reduces tire lifespan by 30%, while overloading by 40% reduces it by 50%. Accelerates engine damage: Overloading causes significant damage to the engine. The increased load leads to insufficient power. Prolonged low-speed driving causes the engine to overheat, exacerbating component damage. It also increases fuel consumption and transportation costs. Heavier steering and increased centrifugal force affect vehicle handling: Overloading increases centrifugal force during turns, reducing driving stability and increasing the risk of accidents. Reduces braking performance and increases unsafe stopping distance: Many factors affect braking distance, and changes in vehicle load directly influence it. When a loaded vehicle brakes, the load shifts forward, increasing the load on the front wheels and reducing it on the rear wheels. This alters ground adhesion and consequently changes the braking distance. A fully loaded vehicle decelerates slower than an empty one. Shortens leaf spring lifespan and reduces vehicle maneuverability: Overloading places excessive stress on leaf springs, causing continuous rebound during operation, which shortens their lifespan. Excessive load also lowers the vehicle body, reducing ground clearance and the vehicle's ability to pass obstacles.

How Many Years Should a Car Be Driven Before Scrapping?

Automobiles are categorized into private cars and commercial vehicles, and the number of years before scrapping depends on the type of vehicle, as detailed below: Regulations for scrapping private cars: For 5-seat family sedans and 7-seat SUVs, as well as non-commercial small and mini vehicles, there is no usage lifespan limit. However, when the normal driving mileage reaches 600,000 kilometers, the state will guide the scrapping process. In addition to the above vehicles, small and mini non-commercial passenger cars, large non-commercial sedans, and wheeled special-purpose machinery vehicles also have no usage lifespan restrictions. Common regulations for scrapping commercial vehicles: Small and mini taxi passenger cars have a scrapping lifespan of 8 years, medium-sized taxi passenger cars 10 years, and large taxi passenger cars 12 years. Public transport passenger cars have a scrapping lifespan of 13 years, while other small and mini commercial passenger cars have a scrapping lifespan of 10 years, and large and medium-sized commercial passenger cars 15 years. Mini commercial trucks have a scrapping lifespan of 8 years, while light and large commercial trucks have a scrapping lifespan of 10 years. The vehicle scrapping process is as follows: The car owner applying for scrapping and renewal must fill out and submit one copy of the "Motor Vehicle Change, Transfer, Modification, Suspension, and Scrapping Approval Application Form," stamped with the owner's seal; Apply at the registration and acceptance counter. For vehicles that have reached the scrapping lifespan, a "Vehicle Scrapping Notice" will be issued. For vehicles that have not reached the scrapping lifespan, the motor vehicle inspection counter will determine whether they meet the scrapping standards and issue a "Vehicle Scrapping Notice" if applicable; The owner can choose a qualified recycling company to dismantle the vehicle by presenting the "Notice"; The recycling company will dismantle the vehicle and take photos after verifying the "Notice." The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut; The owner must submit the "Change Form," "XX Province Vehicle Renewal Technical Appraisal Form," "Scrapped Vehicle Recycling Certificate," and photos of the dismantled vehicle to the motor vehicle inspection counter for verification and signature. The license plates and certificates will be reclaimed, and the scrapping registration will be processed according to regulations after approval.
