What is the Difference Between Part-Time 4WD and Full-Time 4WD?

The difference between part-time 4WD and full-time 4WD lies in the driving time. The specific distinctions between part-time 4WD and full-time 4WD are as follows: 1. The part-time 4WD system requires manual switching between 2WD, high-range 4WD, and low-range 4WD modes. 2. In full-time 4WD, all wheels operate independently at all times during driving. Here is some related information about 4WD: 1. 4WD refers to a vehicle's four wheels moving independently during driving, which is a transmission method with higher cornering limits on roads. 2. It ensures that each wheel receives optimal driving force when the vehicle is cornering at high speeds. 3. 4WD systems are categorized into part-time 4WD, on-demand 4WD, and full-time 4WD. 4. Part-time 4WD is a four-wheel-drive system where the driver can manually choose between 2WD and 4WD.

What does ECU mean in a car?

ECU in a car is the Electronic Control Unit, also known as the vehicle's onboard computer. Its function is to control the vehicle's driving state and realize various functions. The ECU mainly uses data collection and exchange from various sensors and buses to determine the vehicle's status and the driver's intentions, then controls the car through actuators. Common reasons for ECU damage: 1. Not disconnecting the ECU wiring harness during chassis welding repairs; 2. Using a direct thyristor charger to charge when the battery is low; 3. Charger voltage is too high, polarity is reversed, or the ignition switch is turned on or even the generator is started while charging; 4. Sudden disconnection of the battery's positive and negative terminals while the engine is running.

What does AWD mean on a car?

AWD stands for All-Wheel Drive system, which is used in many high-end SUV models or performance cars. Introduction to All-Wheel Drive System: An All-Wheel Drive system refers to a four-wheel drive system that keeps all four wheels of the car constantly powered. Representative of All-Wheel Drive System: The All-Wheel Drive system (AWD) is represented by cars like the Audi Quattro system, where all four wheels are powered at all times. This system ensures that all four wheels of the car maintain driving force constantly. The All-Wheel Drive system includes three differentials: in addition to one differential on each of the front and rear axles, there is also a central differential between the front and rear drive shafts.

What is the D3 gear?

D3 gear is a forward gear. The following is a related introduction about the D3 gear: 1. It means the gear is locked in the 3rd gear. 2. Generally used for mountain driving, it is equivalent to the manual gear of an automatic transmission. 3. Traditional automatic transmission technology structures will add an S gear or D3, D2, D1 to assist in forcing the transmission to work within a certain gear range. The following is an introduction to the function of the D3 gear: 1. It limits the maximum speed of the car, and the principle of the D3 gear is the same as that of a manual transmission. 2. The higher the gear, the faster the speed and the smaller the torque, and vice versa, the lower the gear, the slower the speed and the greater the torque.

What Color of Transmission Fluid Needs to Be Changed?

Transmission fluid needs to be replaced when it turns black or becomes cloudy. Below are the maintenance methods for the transmission: 1. Regularly inspect the transmission: It is essential to check the fluid level in the transmission to ensure it remains within the specified range. Refill as needed based on actual working conditions, ensuring the newly added fluid is of the same type. When changing the fluid, take advantage of the transmission's operation to promptly drain the old fluid and clean the system. 2. Regularly inspect the condition of different connection points in the transmission: During routine maintenance, inspect the condition of all connection points in the transmission to promptly identify any issues such as looseness, wear, or damage. Tighten any loose connections immediately and repair or replace any damaged parts. 3. Maintenance of transmission structural components: Daily maintenance of the transmission should focus on the structural parts, including gears, bearings, and shafts. Regularly check for issues such as gear wear, chipping, or incorrect meshing.

What Does a Yellow Exclamation Mark on the Car Dashboard Mean?

A yellow exclamation mark on the car dashboard indicates an abnormality or malfunction in the corresponding system. There are many indicator lights on the car dashboard with exclamation marks, such as the tire pressure indicator, lighting fault indicator, steering system fault indicator, brake system fault light, transmission fault indicator, and wiper fault indicator. Below is a detailed explanation of the exclamation mark warning lights: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a fault in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a transmission malfunction or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Brake System Fault: A circle with parentheses and an exclamation mark in the middle. This represents a brake system warning, indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire Pressure Abnormality: A horizontal line with parentheses below and an exclamation mark in the middle. This is the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, indicating a malfunction in one of the car lights. Solution: Visit a 4S shop for inspection as soon as possible, or check yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the problem. In addition, during daily use of the vehicle, the fault lights displayed on the dashboard are divided into two colors: yellow and red: Yellow indicates a fault in the corresponding system, but the problem is not very serious. Reduce speed and proceed to the nearest repair point to eliminate potential safety hazards. Red indicates a very serious problem in the corresponding system. In this case, do not continue driving. Pull over immediately and seek professional assistance to prevent unpredictable risks to the vehicle and personal safety. Note that when the car is started, all lights will illuminate for a system self-check and will turn off automatically after the check is completed. If a light does not turn on when the ignition is switched on, remains lit, or lights up while driving, it indicates a fault in the related system. In such cases, seek professional help promptly to inspect and eliminate potential safety hazards.
