Turn signal has no sound due to poor contact or buzzer damage, and needs to be inspected at an auto repair shop. The turn signal is an important indicator light that turns on when the vehicle is turning to alert surrounding vehicles and pedestrians. The turn signal tube uses a xenon tube, with a microcontroller-controlled circuit that alternates left and right flashes continuously. The turn signal uses a flasher to achieve the blinking effect, mainly divided into three types: resistance wire type, capacitor type, and electronic type. The turn signal is the most important device indicating a car's dynamic information, installed at the front and rear of the vehicle body. It turns on when the car is turning, providing safety for driving. Please use the turn signal as required.

What is damaged when the fault code u0101 appears?

Fault code u0101 is an error indicating a dirty throttle issue. Below is an introduction to throttle-related content: 1. Function: The throttle controls the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to generate power. 2. Principle: The principle of the throttle is that the traditional engine throttle control mechanism operates via a cable (flexible steel wire) or rod, with one end connected to the accelerator pedal and the other end connected to the throttle linkage plate. The electronic throttle primarily uses a throttle position sensor to control the throttle opening angle based on the engine's required energy, thereby regulating the amount of air intake.

To What Level Should Car Antifreeze Be Filled?

Generally, the antifreeze reservoir will have a MAX (maximum level) mark and a MIN (minimum level) mark. The car antifreeze should be filled to a level between MAX and MIN. For most family cars, replacing antifreeze requires approximately 4-6 liters, depending on the vehicle model. Methods to determine if antifreeze is low: Check the antifreeze warning light on the dashboard. If it lights up, it is likely due to low antifreeze, though it could also be caused by excessively high engine temperature. Inspect the antifreeze reservoir. If the fluid level is below the MIN mark, do not continue driving and add antifreeze promptly. Check the level markings on the antifreeze reservoir. The normal antifreeze level should be between the MAX and MIN marks. To determine if antifreeze is low, observe the markings—if the antifreeze is below the MIN line, it indicates a shortage.

What type of oil is used for Honda 1.5T engine?

The original oil is the one used for Honda 1.5T, with the oil model being 5W-30. In terms of applicability, the original oil is more suitable for the engine. However, depending on different needs, oils can have other functions, such as noise reduction, fuel efficiency, and power performance. Therefore, you can also choose oils from brands like Mobil, Shell, and Castrol. The viscosity of the oil changes with temperature, so special attention should be paid to its performance under low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand low temperatures of -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother for the car. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the value, the better it can maintain viscosity at high temperatures, which can also be understood as better lubrication performance under high temperatures. The method for changing the oil in a Honda 1.5T is as follows: Wait for the engine temperature to drop, and also allow the oil to flow back to the oil pan; use a wrench to loosen the oil drain plug, and use an oil pan to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to flow out; use a special wrench to remove the oil filter; apply oil to the oil seal of the new oil filter and tighten it clockwise by hand; add the new oil through the oil filler cap on the engine valve cover, generally filling up to three-quarters of the oil can; start the engine and let it run for 5 minutes, then check for any oil leaks at the oil drain plug and oil filter, and repair if necessary; after stopping the engine, pull out the oil dipstick and check that the engine oil is within the standard range.

How to Deal with the Abnormal Noise of Leopard Sunroof?

Abnormal noise in the Leopard sunroof indicates a severe lack of lubrication in the sliding rails. It is necessary to check whether the sliding rails are deformed and perform lubrication maintenance in a timely manner. Below are the precautions for car sunroof maintenance: 1. During the use of the sunroof, clean it regularly. After 2 to 3 months of use, the sunroof should be cleaned, mainly to remove dust and particles from the gaps of the sunroof. When cleaning, use a cloth to first remove the dust on the sealing strip, and after wiping it clean, apply a small amount of butter to the sliding rail tracks. 2. When the vehicle is parked and unused for a long time, clean it regularly. For example, use fine talcum powder to clean the sealing ring and other sunroof components, which can effectively extend the service life of the components.
