TCS in cars stands for Traction Control System. Here is an introduction to the Traction Control System: 1. The Traction Control System is a control system designed to prevent wheel lock-up and skidding during braking, as well as wheel spin during acceleration. 2. The Traction Control System maintains the slip ratio of the driving wheels within the optimal range of 5% to 15% during acceleration. The Anti-lock Braking System (ABS) keeps the wheel slip ratio within the optimal range of 8% to 35% during braking. Within these optimal ranges, both the longitudinal and lateral friction coefficients between the wheels and the road are maximized, ensuring directional stability of the vehicle. 3. The basic working principle is that during braking, the wheel speed sensor measures an AC voltage signal proportional to the rotational speed of the braking wheel and sends this signal to the Electronic Control Unit (ECU). The ECU's processing unit calculates the wheel speed, slip ratio, and wheel acceleration/deceleration. The control unit within the ECU then analyzes and compares these signals and sends brake pressure control commands to the pressure regulator.

Why does the car stall while driving?

The main reasons for vehicle stalling can be categorized into the following four types: 1. Fuel system issues: During normal engine operation, the fuel pump draws fuel from the tank, passes it through the filter into the distribution lines, and then sprays it through the injectors to form an air-fuel mixture. In this process, the fuel pump and injectors are the most prone to failure, followed by filter and fuel line blockages. Please focus on inspecting these two areas. If necessary, clean the fuel lines. To reduce such occurrences, always refuel at reputable gas stations with the correct grade of gasoline, and ensure timely refueling to avoid letting the fuel level drop below the red line. 2. Throttle body blockage: The throttle body is undoubtedly the most critical component and also the most problematic. Generally, maintenance personnel will consider cleaning the throttle body. However, if frequent cleaning doesn't resolve the stalling issue, it usually indicates a fault. Additionally, check the vacuum pump to ensure normal air intake. 3. Abnormal spark plug ignition. Replace spark plugs according to their service life. In gasoline engines, the combustible mixture is ignited by the spark plug near the top dead center of compression. Therefore, when the spark plug fails to function, it naturally causes the vehicle to stall. Typically, replacing the spark plug completely solves the issue. When replacement is inconvenient, temporary solutions like cleaning the electrodes or adjusting the central electrode length can be used as emergency measures. Furthermore, insufficient battery voltage, leakage, faulty ignition coils, or wiring issues can all lead to poor ignition or stalling. 4. Sensor faults causing ECU protective fuel cut-off. Check whether all sensors and actuators are functioning properly. Key sensors include the throttle position sensor, oxygen sensor, and crankshaft position sensor. If the crankshaft position sensor has been replaced, also check if the oxygen sensor is contaminated. Therefore, it is recommended to conduct a comprehensive inspection at a 4S shop, focusing on the spark plugs, fuel pump, and oxygen sensor, followed by ECU matching.

What to Do When Keyless Entry Fails?

When the keyless entry fails to unlock the car doors, there are typically two possibilities: either the car battery is dead, or the key fob battery is depleted. Regardless of the subsequent troubleshooting or repairs needed, the first step is to use the spare mechanical key to unlock the door. Daily precautions for key fob usage: 1. Avoid proximity to electronic devices: Experts explain that under normal circumstances, the original battery of a smart key can last about two years. However, severe electromagnetic interference can also cause the key fob to malfunction. "In certain environments with strong electromagnetic interference, the wireless communication between the smart key and the vehicle may be temporarily disrupted," says an expert. "If the smart key is stored near a mobile phone for extended periods, its chip can be affected by the phone's frequency, leading to temporary failure." Experts warn that since smart keys use low-intensity radio waves, they should not be placed near electronic products or devices such as radios, TVs, computers, or microwaves, which can act as 'nemeses' to the key fob. Electromagnetic waves not only drain the battery but also damage the chip, eventually causing the smart key to malfunction. 2. Avoid rough handling: Experts emphasize that most smart keys have fragile internal circuitry and are prone to damage from strong impacts. Additionally, water exposure can fry the internal wiring, resulting in remote failure. It's also important to avoid leaving the smart key in high-temperature environments like under the windshield or in direct sunlight. 3. Do not store the spare key inside the car: Losing a smart key due to improper storage can lead to significant inconvenience and high replacement costs. Experts advise against keeping the spare key inside the vehicle or together with the smart key. For smart proximity keys, replacing them requires modifying the car's computer parameters and reprogramming a new set of keys. Owners must provide vehicle and identification documents, and manufacturers must supply the corresponding model parameters or codes. Once replaced, the lost key can no longer start the engine. Another solution is to replace all the car locks, which is more secure but involves higher costs and longer repair times.

What is the wading depth of a Corolla?

The wading depth of a Corolla is 300mm. The wading depth of a Corolla is determined by the height of the vehicle's chassis, which is the ground clearance listed in the model's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when passing through waterlogged roads. Therefore, in terms of safe wading depth, SUVs and off-road vehicles have obvious advantages. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a benchmark when passing through waterlogged roads. If the air intake of a Corolla is below the water level during wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it can cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth should not exceed the height of the engine's air intake. Installing a snorkel can increase the height of the engine's air intake, thereby improving the maximum wading depth. If wading is unavoidable, the following safe and correct operations should be performed: Before entering the water, always turn off the auto start-stop function to prevent the engine from automatically restarting after stalling in water, which could cause severe damage due to water intake. Assess the underwater road conditions based on the passage of preceding vehicles and choose a suitable entry point. Observe the path taken by other vehicles and follow their tracks at a low speed, avoiding sudden acceleration or deceleration. On roads prone to water accumulation, use warning water level markers, trees, or the wheels and doors of other vehicles as reference points to estimate the water depth before deciding whether to proceed. Know your vehicle's safe wading depth. If the water depth exceeds half of the tire height or the engine's air intake, avoid entering the water and choose an alternative route instead.

What is the fuel tank capacity of the Honda CR-V in liters?

The 2010 Honda CR-V has a fuel tank capacity of 58 liters, as officially announced. Owners of the 2010 Honda CR-V can also verify this information on their vehicle's configuration sheet. The manufacturer is Dongfeng Honda. Dongfeng Honda Automobile Co., Ltd. was established on July 16, 2003, with its headquarters located in the Wuhan Economic and Technological Development Zone. The company is a joint venture between China's Dongfeng Motor Group Co., Ltd., Honda Motor (China) Investment Co., Ltd., and Japan's Honda Motor Co., Ltd. The Honda CR-V 2010 2.4L Automatic Four-Wheel Drive Premium Navigation Edition, Honda CR-V 2010 2.4L Automatic Four-Wheel Drive Premium Edition, and Honda CR-V 2010 2.4L Automatic Four-Wheel Drive Luxury Edition all use 92-octane fuel, with a fuel consumption of 9.8 L/100km. A full tank can cover a distance of 591 km. The Honda CR-V 2010 2.0L Manual Two-Wheel Drive Urban Edition uses 92-octane fuel, with a fuel consumption of 8.4 L/100km. A full tank can cover a distance of 690 km. The Honda CR-V 2010 2.0L Automatic Two-Wheel Drive Urban Edition uses 92-octane fuel, with a fuel consumption of 8.6 L/100km. A full tank can cover a distance of 674 km. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is usually done by observing the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments. It is advisable to refuel when the gauge shows 2 segments remaining to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safety limit. There is additional space from the safety limit to the tank opening, designed to accommodate fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount may exceed the marked capacity. Other factors affecting fuel consumption include: Vehicle weight: There is a direct correlation between vehicle weight and fuel consumption. A 10% reduction in weight can lead to a corresponding reduction in fuel consumption. Vehicle aerodynamics: A lower drag coefficient results in lower fuel consumption, while a higher drag coefficient increases fuel consumption. Tire pressure: Low tire pressure increases friction and adhesion, leading to higher fuel consumption. Driving habits: Aggressive acceleration and frequent braking can significantly increase fuel consumption. Wind direction: Driving with a tailwind reduces fuel consumption, while driving against the wind increases engine workload and fuel consumption. Road conditions: Driving on flat roads consumes less fuel compared to rough or steep roads. Additional electronic devices: Using extra equipment like air conditioning while driving increases fuel consumption.

Can the Oil Filter Be Reused?

The oil filter cannot be reused. The oil filter used in cars is designed to filter impurities from the engine oil. Every time you change the engine oil, you must also replace the oil filter. Reusing the oil filter can contaminate the newly replaced oil, which may cause certain levels of damage to the engine. It's important to note that oil filters are generally made of paper material. During use, if the filter becomes clogged, its resistance will increase, leading to poor lubrication flow, which can affect the engine's normal operation. The oil filter has a replacement cycle, but this also depends on the quality of the engine oil being used.
