What does the SVS light in a car mean?

SVS indicator light is the engine fault indicator light, which is equivalent to the "engine shape" indicator light; when the vehicle's ignition key is turned on, this light will illuminate and will turn off after the vehicle is started; when the engine ECU detects a fault, the SVS light will illuminate; if this light comes on while the vehicle is in motion, it indicates that there is a fault with the vehicle's engine, and it needs to be repaired as soon as possible. The following is an introduction to the ECU: 1. The role of the ECU: The ECU can collect data through various sensors, and after processing, it can control the engine's operation through control mechanisms. Without the ECU and sensors, the engine cannot function properly. 2. The principle of the ECU: The principle of the ECU is to detect the engine's working conditions through sensors installed in different locations, including engine speed, crankshaft position, exhaust temperature, exhaust oxygen content, and other parameters, and send these signals to a dedicated microprocessor, which processes them and issues control signals to adjust the engine's ignition timing and fuel supply in a timely manner, achieving the desired optimal effect.

Why is there no air coming out of the center vent of the car air conditioner?

If there is no air coming out of the center vent of the car air conditioner, it may be due to reasons such as the center vent switch not being turned on, severely clogged filters, a blown fuse for the blower, or a faulty relay. The car air conditioner is used to adjust and control the temperature, humidity, air cleanliness, and airflow within the car cabin to an optimal state, providing passengers with a comfortable riding environment and reducing travel fatigue. It also creates good working conditions for the driver and plays an important role in ensuring safe driving. There are 5 main reasons why the car air conditioner may not blow air: 1. Check if the vent switch is connected properly and if there is any short circuit. 2. Check the air conditioner fuse to see if it has blown. 3. Check if the air conditioner vent is blocked. 4. Check if the air conditioner motor blower is working properly. 5. Check the vehicle's power distribution system and inspect the battery.

Can You Maintain Your Car on Rainy Days?

Can You Maintain Your Car on Rainy Days? The following are relevant introductions about car maintenance during the rainy season: 1. Brake system maintenance: Since brake fluid easily mixes with water, the accumulation of moisture from humid air on the brake reservoir can easily enter the brake fluid. The presence of air in the brake fluid being compressed can lead to brake failure or inefficiency. Therefore, after continuous rainy days, it is important to check the brake fluid and perform a brake system bleeding process. 2. Wiper system and drainage system maintenance: During regular maintenance, promptly inspect the condition of various switches and gear usage. Also, pay attention to checking the wiper blades and replace them in time when they fail to clean the windshield effectively. Ensure the cleaning of the drainage channels and holes located below the lower part of the front windshield to prevent rainwater accumulation, which could lead to water seeping into the car and potentially causing electronic control system malfunctions or damage. It is essential to clear the drainage holes promptly to avoid water accumulation.

What vehicles can a C4 driver's license drive?

C4 license only permits driving three-wheeled motor vehicles, originally three-wheeled agricultural transport vehicles, with no other vehicle types authorized. Relevant details are as follows: 1. According to regulations, if you already hold a C4 driver's license and have no record of full penalty points in this scoring cycle and the most recent scoring cycle before application, you can apply to upgrade to a C1 license. The process is the same as reapplying to learn for a C1 license. 2. Class C driver's licenses can be divided into five types: C1, C2, C3, C4, and C5. A C1 license allows driving small and mini passenger vehicles, light and mini cargo vehicles, light, small, and mini special-purpose vehicles, as well as all vehicle types under C2, C3, and C4. A C2 license only permits driving small and mini automatic transmission passenger vehicles and light and mini automatic transmission cargo vehicles. C3 allows driving low-speed cargo vehicles, i.e., vehicles with a length less than 6m and a total mass less than 4500kg. C5 permits driving small and mini automatic transmission passenger vehicles specially designed for disabled individuals, and only allows individuals with right lower limb or both lower limb disabilities to drive.

What is the function of a spark plug?

Spark plug function: The spark plug's ground electrode is connected to the metal shell, which is threaded into the engine block via the cylinder head. The insulator primarily serves to isolate the metal shell from the center electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and center electrode, it ionizes the medium between the center electrode and ground electrode to generate a spark, thereby igniting the air-fuel mixture in the cylinder. Spark plug replacement interval: Under normal maintenance conditions, replacement is recommended after 40,000-60,000 kilometers of driving. However, this may vary depending on the brand and engine type, so always refer to the owner's manual. The following standards can serve as reference for maintenance replacement: Platinum spark plugs should be replaced at 40,000 km, standard nickel alloy spark plugs at 20,000 km, and iridium spark plugs at 60,000-80,000 km.

How to Inflate Car Tires?

Connect the air pump's hose, ensuring each section is tightly secured. Plug the air pump's power cord into the car's cigarette lighter socket, making sure the engine is running. Turn on the air pump switch, attach the hose to the tire valve, and tighten the connection nut. When the air pump's displayed tire pressure approaches the standard value, turn off the pump and replace the valve cap. More detailed instructions are as follows: 1. During inflation, constantly monitor the pressure gauge on the air pump. You can apply water to the valve opening to test for leaks. Inflation should be performed on cold tires; tires that have just been driven have heated air inside, which can lead to inaccurate measurements and inflation values. Therefore, wait for the vehicle to cool down before inflating. 2. Purchase a high-quality tire pressure gauge with accurate measurements. An inaccurate tire pressure gauge can directly result in incorrect tire pressure, posing a potential hazard to both the car tires and safety. After inflating at a 4S shop, car owners can use their own tire pressure gauge to measure again and compare the results.
