How to Calibrate Honda Tire Pressure Monitoring System?

When Honda detects abnormal tire pressure, a warning to check tire pressure will appear on the dashboard. Initialization and calibration steps: Start the engine and keep the gear in "P" position; Perform the following operations on the smart screen: 1. Select "HOME", 2. Select "Settings", 3. Select "Vehicle", 4. Select "Tire Pressure Monitoring System Calibration", 5. Select "Calibrate". Tire pressure monitoring is the real-time automatic monitoring of tire pressure during vehicle operation, with alerts for tire leaks and low pressure to ensure driving safety. There are three commonly used tire pressure monitoring methods: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data. The system automatically alerts when tire pressure is too low or there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of both systems mentioned above, equipping direct sensors in two diagonally opposite tires and incorporating a 4-wheel indirect system. Compared to using only a direct system, this hybrid system can reduce costs and overcome the limitation of indirect systems in detecting simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires as a direct system does.

When can I schedule Subject 1 after the medical examination?

After passing the medical examination, the driving school needs to submit the application form and the physical condition certificate to the vehicle management office for review. After the review is completed, Subject 1 can be scheduled. In some places, after the review is completed, about 10 days of study hours are required before scheduling the Subject 1 exam. Before scheduling, you should review the Subject 1 exam materials and practice test questions. Enrollment in the driving school is only preliminary. After enrollment, the driving school submits the materials to the vehicle management office. Upon success, the vehicle management office will issue a serial number, which indicates successful enrollment. After successful enrollment, you can schedule Subject 1. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," Subject 1 consists of 100 single-choice and true/false questions, each worth 1 point. If you answer 11 questions incorrectly during the exam, the system will automatically submit the test and end the exam. Subject 1 exam content: Driving 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; Special knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 exam precautions: During the exam, students should dress appropriately—no slippers allowed. Electronic devices and bags are not permitted in the exam room. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen. Before entering the exam room, store personal belongings in a locker. In the exam room, the identity verification station will assign a seat. After finding your seat, begin the exam. Ensure the camera is aimed at you and follow exam discipline. If you fail the first attempt, a retake is available the same day. If you fail again, you must pay to reschedule. After the exam, queue to receive your score report and sign it. Failure to sign renders the result invalid. There is no limit to the number of times you can schedule Subject 1. Each subject can be taken once, with one retake if you fail. If you do not take the retake or fail it, the exam ends, and you must reschedule. For Subject 2 and Subject 3, there are only five exam attempts. Subject 2 and Subject 3 exams can be scheduled after ten days. If you fail the Subject 3 safe driving knowledge test, the previously passed road driving skills test results remain valid. There are three subjects in the driving test: 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 (under the Ministry of Public Security Order No. 123) does not include Subject 4.

What are the reasons for the yellow engine warning light in BMW cars?

Sensor issues, car maintenance problems, fuel quality issues, poor combustion of the air-fuel mixture, engine intake problems, turbocharging issues, exhaust problems, and anti-theft system malfunctions are the main reasons that cause the engine warning light to illuminate. Additionally, when starting the car, the vehicle performs a self-check on the engine system. Normally, the engine warning light will turn off after the self-check is completed. If it remains on for an extended period, it is advisable to seek professional help at a repair station promptly to diagnose and eliminate potential safety hazards. The following are detailed explanations for each type of fault: Sensor problems: Sensors include those for coolant temperature, crankshaft position, air flow, intake temperature, oxygen levels, etc. When these sensors are damaged, have poor contact, or experience signal interruptions, the car's ECU cannot accurately obtain engine data, which triggers the engine warning light. In such cases, it is important to visit a repair center promptly for professional diagnosis and to eliminate safety hazards. Maintenance issues: Poor engine maintenance is the most common cause of the engine warning light illuminating. Vehicles have specific maintenance schedules, and failure to adhere to these schedules, combined with poor driving habits, can increase the burden on the engine, eventually causing the engine warning light to come on as a reminder of a fault. Fuel quality issues: This refers to both fuel and engine oil. The fuel used in cars usually has a specific octane rating, and engine oil can be semi-synthetic or fully synthetic. Manufacturers typically recommend which fuel octane rating and type of engine oil to use. If the owner does not follow these recommendations, prolonged use can lead to engine wear, triggering the warning light. It is essential to use the correct fuel octane rating and appropriate engine oil for the vehicle. Poor combustion of the air-fuel mixture: Faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can cause poor combustion of the air-fuel mixture in the engine. This leads to engine carbon buildup or knocking, which the oxygen sensor detects and reports to the ECU, resulting in the warning light illuminating as a warning. Intake problems: The engine requires air for combustion, and the air filter plays a crucial role in this process. If the air filter is dirty or not cleaned regularly, it can affect the engine's air intake, potentially leading to blockages over time. In severe cases, this can cause the engine warning light to come on. Turbocharging issues: Problems with the intake turbocharging system or the turbocharger itself can also trigger the engine warning light. The most common issue is a damaged turbocharger, which may also cause symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Exhaust problems: The rear oxygen sensor, catalytic converter, exhaust camshaft, and bearings can also cause the engine warning light to illuminate. The most common issue is a faulty catalytic converter, which can result from using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions. Anti-theft system: If the car's electronic anti-theft system malfunctions or if the anti-theft controller does not match the engine's electronic controller, the anti-theft system can prevent the engine from operating correctly, causing the warning light to illuminate. Solutions for the engine warning light: If the engine warning light is on and the car cannot start, this may be due to a faulty fuel pump or ignition components. It is recommended to call for assistance immediately. If the engine warning light is on and the car can still be driven but exhibits severe shaking or loss of power, pull over safely and call for roadside assistance. If the engine warning light is on but the car drives normally, it may be due to a faulty sensor. In this case, you can continue driving cautiously at low to moderate speeds but should visit a repair shop as soon as possible to address the issue.

Will Running a Red Light Always Be Captured? When Will You Be Notified?

If there are cameras, the violation will be photographed, and you will generally receive an SMS notification within 7-13 days. Whether it's running a red light while turning left or going straight, both are illegal acts. According to the relevant provisions of the "Road Traffic Safety Law," vehicles must obey traffic signals, including traffic lights, traffic signs, road markings, and the directions of traffic police. If both the left-turn signal and the straight signal are green, going straight from a left-turn lane violates the designated lane rules. When the left-turn signal is red, running the red light should be penalized. Here are some tips to avoid running a red light: First, look at the arrow light, then the circular light: Currently, there are two types of traffic lights: arrow traffic lights and circular traffic lights. If arrow lights are present, check the arrow light first and then the circular light to avoid running a red light. Note: When encountering a circular red light, you may turn right. However, if the right-turn arrow is red, turning right is prohibited and will be penalized as running a red light. Brake in time: When the red light turns on, do not let the front of your vehicle cross the stop line. If the front wheels accidentally cross, and the rear wheels follow, the electronic camera will capture it, and you will be penalized for running a red light. If the front wheels have just crossed the stop line when the light turns red, do not proceed through the intersection; wait for the green light. Check the green light countdown before proceeding: When the green light flashes, if there is a countdown, use it to judge whether to proceed. If there is no countdown, and you are close to the intersection with high speed, you may proceed to avoid running a red light due to delayed braking. If your speed is low and you are far from the intersection, brake immediately to avoid running the red light. Article 38 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" states: When the green light is on, vehicles are permitted to proceed, but turning vehicles must not obstruct the passage of straight-moving vehicles or pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue. When the red light is on, vehicles are prohibited from proceeding. At intersections without non-motorized vehicle or pedestrian signals, non-motorized vehicles and pedestrians must follow the motor vehicle signals. When the red light is on, right-turning vehicles may proceed if they do not obstruct the passage of other vehicles or pedestrians. Running a red light is not illegal under the following circumstances: Yielding to emergency vehicles: Yielding to ambulances, fire trucks, or other emergency vehicles. If captured by surveillance cameras while yielding, manual review will not record the red-light violation. Even if recorded, you can apply for reconsideration at the traffic police department. Extreme weather: When visibility is extremely low, and even electronic police cannot clearly see the traffic lights. Photos of violations may be blurry, and running a red light by mistake will not be penalized. Emergency situations: When rushing a critically ill patient to the hospital, running multiple red lights may occur. After delivering the patient, provide proof from the hospital or the rescued individual to the traffic police for verification. If confirmed, the violation records can be cleared. If possible, call an ambulance to avoid accidents caused by running red lights. Police direction: During peak hours, traffic police may temporarily direct traffic at key intersections. Drivers must follow the officers' hand signals. The traffic police department states that according to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," when the yellow light flashes at an intersection, vehicles that have already crossed the stop line may continue. If you rush through after the yellow light turns on, it will still be considered running a red light if captured.
