After opening the driver's door, there is a panel on the side of the dashboard. Unscrew the panel with a screwdriver, and the fuse box is inside; the relay is located in the relay box. Relay Overview: A relay is an automatic control device where the output undergoes a sudden change when the input (electrical, magnetic, acoustic, optical, or thermal) reaches a certain value. Automotive relays are the relays used in vehicles. Relay Characteristics: Automotive relays have high load-switching capacity, impact resistance, and vibration resistance. The power supply in vehicles is mostly 12V, and the coil voltage is mostly designed for 12V. In the engine compartment, the ambient temperature range requirement is -40°C to 125°C, while in other locations, it ranges from -40°C to 85°C.

Last month, I just helped a friend check the fuel pump fuse and relay on a Volkswagen Lavida. The car wouldn't start, and we found that it's usually located in the fuse box in the engine compartment. Specifically, it's the black box near the windshield on the driver's side after opening the hood. Inside, there are a bunch of fuses and relays, with their positions labeled—like SC, SD, etc. You'll need to refer to the owner's manual diagram to confirm which one it is. In my case, I had to check the manual to find out it was labeled SD18. Fuel pump relay issues are common; if there's no power or it's faulty, the fuel pump won't work, and the car won't start. For friends new to this, be careful to turn off the power before replacing it to avoid short circuits and damaging other parts. In short, checking is the first step—don't rush to get it repaired, saving both time and money.

What is the Principle of Car Turning?

The principle of car turning is actually not very difficult. Essentially, all four wheels of the vehicle rotate around the same center point, with the rear wheel axle as the reference. The front two wheels must also align with this same center point for the vehicle to achieve normal turning. Here is an extended explanation: Role of the Differential: To enable normal turning, vehicles are equipped with a differential on the rear axle. This allows the tire closer to the center point to rotate slower while the tire farther from the center rotates faster, facilitating smooth turning.

What Does the Yellow Engine Light on the Dashboard Mean?

The yellow engine light on the dashboard indicates that the engine fault light is on, signaling a malfunction in the vehicle's engine. Possible reasons for the engine fault light include turbocharging issues, substandard exhaust emissions, clogged fuel injectors, throttle position sensor problems, or, in some vehicles, transmission system faults that are indicated via the engine fault light. Detailed explanations of the causes are as follows: Sensor Issues: Sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors may be damaged, have poor contact, or experience signal interruptions. When the vehicle's ECU cannot accurately obtain engine data, the engine fault light will illuminate. In such cases, the sensors need to be inspected and repaired. Turbocharging Issues: Problems with the intake boost pipes or turbocharger can also trigger the engine fault light. The most common issue is a damaged turbocharger, accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. In this scenario, the turbocharger requires repair. Exhaust Issues: Faults in components such as the rear oxygen sensor, catalytic converter, exhaust camshaft, and bearings can cause the engine fault light to illuminate. The most frequent issue is a malfunctioning catalytic converter. Factors like using leaded gasoline, lead- or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system failures can contribute to catalytic converter problems. In such cases, the catalytic converter needs to be repaired.

Is it necessary to apply a car wrap for a 300,000 RMB car?

It is not necessary to apply a car wrap for a 300,000 RMB car. A car wrap, also known as a paint protection film, primarily serves to protect the car from rain, dirt, and scratches. Below is an extended explanation: Frequent cleaning: The car's exterior is sufficiently durable, so rain and dirt dripping onto the surface won't cause significant damage. As long as the car is cleaned regularly, it will still maintain a clean and attractive appearance. The car body has self-protection capabilities: Another key point is the claimed scratch protection feature of car wraps, which is questionable. From production to leaving the factory, the car body undergoes multiple processes such as sheet metal work, stamping, and paint finishing. Therefore, the car body itself already has sufficient self-protection capabilities. A plastic film like a car wrap cannot effectively prevent scratches. Thus, applying a car wrap is truly unnecessary.

Will opening car windows on the highway result in penalty points?

Opening car windows on the highway does not result in penalty points, but it is not recommended to open windows while driving at high speeds because higher speeds create greater wind resistance. If only one window or two windows on different sides are opened, it will generate significant resistance, which can affect fuel consumption. Here are the reasons why it is not advisable to open windows while driving on the highway: 1. Increased fuel consumption: At high speeds, the car's streamlined design effectively reduces wind resistance, but opening windows disrupts the airtightness, leading to greater air resistance and consequently higher fuel consumption. 2. Increased noise: Opening windows at high speeds significantly increases wind noise, reducing comfort. 3. Dirty interior: Driving with windows open on the highway makes the interior/ceiling prone to accumulating dust. 4. Higher risk of traffic accidents: The typical speed on highways is around 120 km/h, and many drivers store luggage or tools in the trunk. Strong winds from open windows can cause imbalance, potentially leading to traffic accidents.

What is the principle of the two wires in the reverse switch?

The principle of the two wires in the reverse switch is controlled by the controller motherboard for forward and reverse rotation, with the internal processor of the controller handling the conversion. There is a reverse signal wire on the reverse gear controller, which can be connected to the on-off switch on the right handlebar along with the negative terminal. The direction of the power input pulley on the engine side remains unchanged, while the reverse output gear inside the transmission engages with the output shaft, driving the output shaft to rotate in the opposite direction, ultimately causing the wheels to rotate backward for reversing. Below is an extended introduction: Reverse function: The controller has an added reverse function, which is disabled during normal riding. When the user stops, pressing the reverse function key enables assisted reversing, with the reverse speed not exceeding 10 km/h. High-speed control: The latest microcontroller designed specifically for motor control is used, incorporating a new BLDC control algorithm suitable for high-speed (below 6000 rpm), medium-speed, or low-speed motor control.

Why does the throttle jerk and feel weak when accelerating?

Here are the reasons for throttle jerking and weak acceleration: 1. Fuel quality issues: If low-grade gasoline is used, the octane rating is insufficient, leading to weak acceleration, reduced engine power, and increased fuel consumption. Additionally, carbon buildup in the fuel system, fuel pump failure, or clogged fuel filters can also cause a drop in engine power. 2. Insufficient oil pressure: Low oil pressure and poor sealing. Poor-quality oil can also lead to insufficient engine power, reduced fluidity, and increased driving resistance. 3. Engine issues: Besides fuel, the engine also requires air. If components like the air filter or throttle body are clogged or malfunctioning, resulting in insufficient air intake, the car will experience weak acceleration, slow speed increase, and a jerking sensation. 4. Ignition system issues: If the spark plugs are heavily carbonized and misfiring, it can also affect engine acceleration. 5. Throttle body, fuel injectors, and intake manifold: Excessive carbon buildup in the throttle body, fuel injectors, or intake manifold can cause jerking. Regular carbon cleaning is recommended.
