EPC in a car stands for the Electronic Power Control system, which typically supports the functions of ABS and ASR. When the EPC light appears on the dashboard, it indicates a fault in the engine or electronic system. If the light remains constantly illuminated or flashes during ignition or while driving, it means the management system has detected an issue with the engine or electronic system. Reasons for the EPC light to illuminate include: 1. Faults in the intake system, such as leaks or blockages; 2. Dirty throttle body with excessive carbon buildup; 3. Use of substandard fuel; 4. Abnormal cylinder pressure or poor operating conditions; 5. Occasional faults or false alarms; 6. Valve faults, sticking, or carbon buildup; 7. ECU malfunction.

Why does 12123 show an accident as unprocessed?

When handling traffic violations on the 12123 platform, if you paid the fine but no points were deducted, it may be due to data delay. Additionally, you can check the unpaid records to find the penalty notice number, and then proceed to pay at the bank or through relevant online payment software. If it is not displayed, review your violation records to check the status of the corresponding item. Legal provisions: Article 114 of the Road Traffic Safety Law states that the traffic management department of the public security authority may impose penalties on the owner or manager of a motor vehicle that violates the law based on traffic monitoring records. If the driver can be identified, penalties may be imposed in accordance with the provisions of this law.

What does the S gear in automatic transmission mean?

S gear is the sport mode of a car ("S" stands for "sport"). Many automatic transmission cars are equipped with an S gear, and some high-end models of A-class cars also feature an S gear design. When the gear is in D position, shifting to S gear manually puts it in first gear. Pushing towards (+) increases the gear by one (second gear), and another push brings it to third gear, with a maximum of three gears. Pulling towards (-) decreases the gear by one. Precautions for using S gear: S gear should not be used frequently: Since S gear only delays upshifting without changing other working processes, it inevitably increases the transmission load in a short time, accompanied by a rise in temperature, which in turn accelerates wear. Therefore, try not to use S gear for extended periods. Do not engage S gear at startup: This actually has a counterproductive effect on speed improvement. If the car is not carrying heavy loads, doing so will instead delay the speed increase.

How long does the first car maintenance usually take?

Car first maintenance time is very fast, about an hour or so, new car first maintenance is mainly to replace the engine oil and oil filter, replacing these two items is very fast, mainly to check other parts of the car. Here are the relevant introductions: 1. After buying a new car, it needs a break-in period, which is usually said to be three months or 5000 kilometers. After replacing the engine oil and oil filter, the engine's operating condition will be better than before, which is the role of the break-in. 2. Engine oil is very important for the engine. Engine oil plays a certain role in lubrication and cleaning in the engine. If the engine lacks oil, the engine cannot operate normally. Turbocharged cars should use fully synthetic oil, and naturally aspirated cars should use semi-synthetic oil. Because when the turbocharged engine is working, the engine speed and temperature are relatively high, so the lubrication requirements are also higher, and the oil used is also different from that of the naturally aspirated engine.

How often should the air filter and cabin air filter be replaced?

The replacement intervals suggested in the vehicle maintenance manual are as follows: the air filter should generally be replaced every 20,000 to 60,000 kilometers. If the driving mileage is low, it is recommended to replace it every 12 months. The cabin air filter should be replaced approximately every 10,000 kilometers. If not replaced for a long time, it will affect the performance of the air conditioning system and the health of the vehicle occupants. Cabin Air Filter: The cabin air filter is an important component of the vehicle's air conditioning system. Its main function is to filter bacteria, PM2.5, moisture, pollen, dust, and other particles from the air. It is recommended to inspect both the air filter and cabin air filter during each maintenance service. The vehicle's air filter is located in different positions depending on the intake design and engine structure, typically found in the air cleaner on the engine intake pipe. The cabin air filter is usually installed under or inside the glove compartment on the passenger side, while in some models, it is located under the windshield in front of the passenger seat. Function of the Cabin Air Filter: It absorbs fine particles, reduces respiratory discomfort, minimizes irritation for allergy sufferers, and protects the air conditioning cooling system. Without the cabin air filter, these particles can enter the cabin, contaminating the air conditioning system, reducing cooling efficiency, and causing allergic reactions, lung damage, and irritation from ozone exposure, all of which can affect driving safety. Dirty Cabin Air Filter: A dirty cabin air filter can become clogged with debris, reducing airflow, impairing cooling performance, increasing fuel consumption, and causing noise. It can also shorten the lifespan of the air conditioning system. Residual contaminants on the filter can breed bacteria and mold, posing health risks to passengers and potentially leading to serious illnesses. Air Filter: Also known as an air cartridge or air cleaner, it is a filter used in engineering vehicles, automobiles, agricultural machinery, laboratories, sterile operating rooms, and other precision environments. Function of the Air Filter: It filters airborne particles, ensuring clean air enters the cylinders and preventing dust from being sucked into the engine, which can accelerate wear on piston assemblies and cylinders. Dirty Air Filter: Using a dirty air filter while driving can restrict engine airflow, leading to incomplete fuel combustion, unstable engine operation, reduced power, and increased fuel consumption. Therefore, it is essential to keep the air filter clean or replace it promptly.

What number to call when a car is blocking the way?

When a car is blocking the way, solutions are as follows: Navigation Information Service: The directory assistance function of the Navigation Information Service has been upgraded. Car owners can call the Navigation Information Service to find the contact information of the corresponding car owner for moving the vehicle, achieving the goal of moving the car through friendly negotiation. Automatic Fault Reporting: If the Navigation Information Service cannot find the information or the other party deliberately refuses to move the car, you can call the Automatic Fault Reporting. The Automatic Fault Reporting is a department set up by the public security traffic management authorities to receive public reports of traffic accidents, dispatch officers to handle various reports and requests for help, and also to handle public reports, complaints, and inquiries regarding traffic management and traffic police law enforcement. In this case, the power of the traffic police can be used to deal with such deliberate refusal to move the car. Government Service Convenience Hotline: After the Government Service Convenience Hotline's vehicle moving service is activated, some car owners cooperate well and the problem can be solved within two or three minutes. However, some car owners are uncooperative and refuse to show up. The hotline staff have to repeatedly urge them until they move the car. Reporting to Insurance: You can seek assistance from the insurance company. If the car is scratched, the insurance company will immediately contact the car owner to handle the accident. The car owner will usually arrive within 3 minutes and come to move the car obediently.
