It depends on the specific situation of driving through water. After driving through water, the transmission, differential, front and rear axles, and differential may all be exposed to water. Generally, water entering the transmission is mainly caused by the following two situations: Water level exceeds two-thirds of the wheel: If the water level exceeds two-thirds of the wheel, the probability of water entering the transmission is around 80% to 90%. If the water has already reached the level of the dashboard, the transmission is 100% certain to have water inside. Water splashes into the transmission during oncoming traffic: When encountering oncoming traffic, if there is excessive water on the road, it may cause water to enter the transmission. Once water enters the transmission, the performance of the transmission fluid will be affected. The performance of the transmission fluid will also degrade, leading to clutch slippage.

What lights to use when passing through an intersection?

Use low beam when passing through an intersection. Nighttime light usage: When driving on well-lit roads, low beam should be used; when following another vehicle, low beam is also necessary to allow the preceding vehicle to observe the rear through the rearview mirror; when meeting an oncoming vehicle within 150 meters, it is also required to switch from high beam to low beam. Passing through special road sections: When driving at night through slopes, arched bridges, crosswalks, sharp curves, uphill roads, or when overtaking vehicles ahead, it is necessary to alternate between high and low beams, mainly to alert other vehicles that your vehicle is preparing to pass through that section of the road.

Why does the tire pressure alarm go off at 1.8?

The reason for the tire pressure alarm at 1.8 bar is due to prolonged underinflation, which triggers the tire pressure monitoring light. Check if the tire pressure sensor is functioning properly. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes the steering wheel to feel heavy and may lead to drifting, compromising driving safety; Increases movement in various parts of the tire, causing excessive rolling and abnormal heat generation; Reduces the functionality of the cords and rubber, leading to delamination or cord breakage, excessive friction with the rim, resulting in bead damage and abnormal wear; Multiplies the friction between the tire and the ground, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to a blowout; Increases tire body deformation, making the tire sidewalls prone to cracking, while generating flexing movements that cause excessive heat, accelerating rubber aging, fatigue of the cord layers, and cord breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear. Solutions for insufficient tire pressure: If no damage is visible, simply inflate to the normal tire pressure and reset the tire pressure system; If a puncture is found during inspection, drive to a tire shop promptly for repair, then reinflate; If the tire pressure warning reappears after inflation without any punctures, it may be due to air leakage caused by rim deformation. It is recommended to inspect the rim and replace it if necessary.

What Causes the Reversing Camera to Not Respond When the Car is in Reverse Gear?

Damage to the reversing camera's probe, signal line faults in the camera, or malfunctions in the gear position sensor can all cause the reversing camera to not respond. Causes: Damage to the reversing camera's probe, signal line faults in the camera, malfunctions in the gear position sensor, poor line contact, aging of the frequency power line, reduced chip photosensitivity due to prolonged use of the reversing camera, obstruction of the reversing camera by foreign objects, or malfunction of the reversing camera display screen. Solutions: When the car is just started, it might interfere with the operation of the reversing camera. Try restarting to see if the situation improves. It could also be electromagnetic interference from other electronic devices in the car. Try turning off the radio or music player before starting again.

What is 100cc?

100CC equals 100 milliliters. Conversion of volume units: Milliliter is a unit of volume. 1L=1000mL. 1000 milliliters=1000 cubic centimeters=1 cubic decimeter. 1 milliliter=1CC. 1 milliliter of liquid water=1 cubic centimeter of liquid water. 1 milliliter=1 cubic centimeter. Explanation of CC: CC is the English abbreviation for cubic centimeter. CC is a measure of volume, while milliliter is a measure of capacity. 100cc of water equals 100ml of water, which is 0.1 liters of water. For other substances, due to different densities, direct conversion is not possible.

What does TCU mean?

Transmission Control Unit (TCU), the automatic transmission control unit, is commonly used in AMT, AT, DCT, CVT and other automatic transmissions to achieve automatic shifting control, making driving easier. It is generally installed inside the transmission. Only vehicles with automatic transmissions have a TCU. The TCU can detect certain data, such as engine speed and vehicle speed. Using this data, the TCU can adjust the transmission to perform gear shifts. Functions of the TCU: Target gear (ratio) decision; actuator control; fault diagnosis; fault handling, etc. The TCU consists of a 16-bit or 32-bit processor, signal processing circuits, power drive modules, etc., and must undergo strict electromagnetic compatibility testing. The operating temperature depends on the installation location. If installed in the cabin, the required temperature range is lower, typically -40°C to 90°C. If installed in the engine compartment, the temperature range is usually -40°C to 140°C. The TCU communicates with the ECU, ABS/ESP, BCU, and other onboard computers via the CAN bus. In case of transmission failure, it controls engine torque, limits gears, and enables the limp-home function. Major TCU suppliers include Continental Automotive, Bosch Automotive, Delphi, Denso, Hitachi, etc. TCUs have different shift logic groups. Many automatic transmissions have an S-gear, which is the sport mode. When sport mode is activated, the transmission's shift logic changes, and the engine's operating mode adjusts accordingly. During normal operation, most transmissions shift between 2000 RPM and 3000 RPM. In sport mode, the transmission does not shift until the engine reaches the redline. The transmission is a crucial component of a vehicle. A car's overall driving performance depends not only on the engine and chassis but also largely on the transmission. A high-quality transmission can compensate for engine shortcomings, while a poor one can hinder engine performance. Having a transmission with intelligent shift logic, fast shift speeds, and durability is essential.

Is it okay to stop after one crystal coating treatment?

Yes, it is acceptable to stop after one crystal coating treatment for your vehicle's paint, as it will not negatively affect the paint. The benefits of crystal coating for vehicle paint: Crystal coating effectively protects the vehicle's paint, maintains its shine, and prevents minor scratches. It is a highly effective method for paint protection, especially suitable for vehicles parked for extended periods. Methods to protect vehicle paint: Applying a paint protection film (PPF) is currently one of the best ways to protect your vehicle's paint. PPF effectively shields the paint from sun-induced fading, prevents severe scratches, and minor scrapes will not damage the paint, making it an excellent choice.
