TC stands for Traction Control System in English, which is a traction control system designed to provide optimal traction for the vehicle under various driving conditions. 1. If the traction control switch next to the gear lever is turned off, the indicator light will illuminate. 2. If accidental pressing is ruled out, it indicates a fault in the traction control system. Additional information: The following situations can cause the traction control system warning light to illuminate: 1. Solenoid valve failure; 2. Dirty engine oil clogging the solenoid valve filter; 3. Wear on the actuator gear and impeller leading to oil pressure leakage and triggering the alarm; 4. Dirty throttle body, with an opening reaching 20%, causing the engine computer to misjudge a TC fault.

I often see the TC indicator light up on the dashboard while driving, and I was quite confused at first. Later, after checking some information, I learned that TC stands for Traction Control System, which prevents the wheels from slipping when starting or turning. If you're driving in rain or snow, the wheels might lose grip, and if the TC light flashes, it means the system is applying brakes or adjusting engine output to help stabilize the car. However, if it stays on continuously, it might indicate a system issue or that it has been manually turned off. For safety, I recommend keeping it enabled normally. If the light stays on, find a flat place to stop and check the vehicle manual or try restarting the engine. Remember, timely action is crucial because without this protection, minor accidents are more likely on slippery roads. Additionally, some cars have related indicator lights like the ESP light, which are part of the auxiliary safety systems. They don’t affect driving but require extra attention.

What causes the humming sound when turning the steering wheel?

Reasons for the humming sound when turning the steering wheel are introduced as follows: Friction between plastic components: In this case, you can go to a 4S shop to replace the power steering fluid. Friction between the steering column and floor mat: The solution is to adjust the belt tension or replace the belt. Faulty airbag clock spring inside the steering wheel: Aging of the steering tie rod end with play, leaking of the steering gear dust cover, in this case, you may consider replacing the steering wheel. Steering gear failure: The solution is to replace the steering gear, replace the dust cover, or reapply grease. Faulty plane bearing or top rubber: The solution is to replace the steering tie rod end and perform a wheel alignment.

Is it correct to yield to straight-going traffic when turning and yield to right-turning traffic when turning left?

Yielding to straight-going traffic when turning and yielding to left-turning traffic when turning right. The relevant details are as follows: Yielding to straight-going traffic when turning left: Yielding to left-turning traffic when turning right refers to the rule that left-turning vehicles must yield to straight-going vehicles, and right-turning vehicles in the same direction must yield to left-turning vehicles. When a vehicle passes through an intersection regulated by traffic signals, it should enter the guiding lane according to the intended direction of travel. Other situations: Vehicles preparing to enter a roundabout must yield to vehicles already inside the roundabout; when turning left, the vehicle should turn close to the left side of the intersection center point. Turn on the turn signal when turning, and use low beams when driving at night. When encountering a green light, pass through in sequence; when encountering a red light, stop in sequence outside the stop line. If there is no stop line, stop outside the intersection.

Is it serious if water reaches the car seats?

It is serious if water reaches the car seats. Here is relevant information: Water submersion height: The severity of a flooded car depends on the height of water submersion and whether the vehicle was started in water; Water reaches under the seats: If the water only reaches under the seats, this height has not yet reached the vehicle's air intake, nor the fuse box and dashboard. After thorough cleaning, the impact on the vehicle is relatively minor; Timely repairs: If the water reaches the transmission, oil pan, and exhaust pipe, then during cleaning, it is necessary to replace the transmission fluid, engine oil, and brake fluid, as well as clean and maintain the vehicle's braking system, exhaust pipe, and catalytic converter. This can further reduce the impact of flooding on the vehicle's subsequent use.

Can the clutch release and acceleration be performed simultaneously?

Do not press the clutch and accelerator simultaneously; always release the accelerator first before pressing the clutch. When shifting gears, first apply the brake to reduce speed, then press the clutch to shift. For stopping, you can directly press the clutch and brake. The correct coordination between the clutch and accelerator is as follows: When starting: Press the clutch with your left foot, apply the brake with your right foot, engage first gear, release the handbrake, and prepare to shift by accelerating. Move your foot to the accelerator pedal to gently apply some gas while continuing to release the clutch for a smooth start. Once the car starts moving steadily, fully release the clutch with your left foot and prepare to shift by accelerating. When upshifting: Release the accelerator pedal, quickly press the clutch pedal with your left foot, shift the gear lever to the appropriate gear, release the clutch pedal, and while doing so, slowly press the accelerator with your right foot. When downshifting: First apply the brake to reduce speed, lightly press the accelerator with your right foot, lift your right foot, quickly press the clutch pedal, shift the gear lever to the appropriate gear, release the clutch pedal, and while doing so, slowly press the accelerator with your right foot.

Is There a Market for Diesel Three-Way Catalytic Converters?

Diesel three-way catalytic converters are indeed recycled. Since these converters contain precious metals, repair shops collect them and sell them to upstream recyclers. After refining, a certain amount of precious metals can be extracted from the converters, giving them high economic value. Driven by profit, a recycling industry chain has naturally emerged. Below is relevant information about three-way catalytic converters: Appearance: A three-way catalytic converter looks like a metal can from the outside, but inside it contains a 'substrate' for purifying exhaust gases. This honeycomb-shaped ceramic substrate is coated with a precious metal slurry, primarily composed of platinum, rhodium, and palladium. Exhaust purification function: The precious metals act as catalysts, reducing hydrocarbons (HC) and carbon monoxide (CO) in the exhaust into water and CO2, while breaking down nitrogen oxides (NOx) into nitrogen and oxygen. This is the exhaust purification function of a three-way catalytic converter.

Is it necessary to go to a 4S shop to replace the bumper?

It is not necessary to go to a 4S shop. Replacing the bumper itself does not pose any technical difficulties, and general mechanics can handle it. The main difference is that the bumpers at 4S shops are usually sourced directly from the manufacturer, offering better quality, while repair shops outside typically use aftermarket parts, which are often of inferior quality. Here are some related introductions: Introduction to car bumpers: The car bumper is a safety device designed to absorb and mitigate external impacts, protecting the front and rear of the vehicle. Many years ago, car bumpers were made of steel plates pressed into channel steel, riveted or welded to the frame rails, leaving a noticeable gap from the body, which looked quite unattractive. With the development of the automotive industry and the widespread use of engineering plastics, car bumpers, as an important safety device, have also undergone innovation. The role of car bumpers: Today, the front and rear bumpers of cars not only maintain their original protective functions but also strive for harmony and unity with the vehicle's styling and pursue lightweight design. The front and rear bumpers of cars are made of plastic, commonly referred to as plastic bumpers. Generally, a car's plastic bumper consists of three parts: the outer panel, cushioning material, and crossbeam. The outer panel and cushioning material are made of plastic, while the crossbeam is formed from cold-rolled sheet metal pressed into a U-shaped channel; the outer panel and cushioning material are attached to the crossbeam.
