Fault code u0101 indicates a communication loss with the transmission control module, which may be caused by wiring issues or connector problems. After this fault code appears, it is recommended that the car owner visit a professional repair shop or a 4S store for maintenance by a professional technician. The transmission control module is also called TCU, commonly used in AMT, AT, DCT, CVT and other automatic transmissions to achieve automatic transmission control, making driving simpler. The TCU is similar to the ECU, where the ECU controls the engine and the TCU controls the automatic transmission. The TCU is generally located in the engine compartment, shaped like a square or rectangle, with a metal casing and many heat sinks on the casing.

What does a yellow exclamation mark mean?

There are four possible scenarios when a yellow exclamation mark appears on the car dashboard: general malfunction, automatic transmission failure, abnormal tire pressure, and lighting system fault. Below is a detailed analysis of these four situations: General Malfunction: A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance or components and functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. It is necessary to visit a 4S shop for inspection to identify the source of the problem. Automatic Transmission Failure: A yellow gear symbol with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or transmission fluid level below the normal range. Transmission fluid should be replaced promptly. Abnormal Tire Pressure: An exclamation mark inside a horizontal line under a bracket represents the tire pressure monitoring warning light. This light illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting System Fault: A yellow bulb symbol with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the vehicle's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue. There is also a red exclamation mark inside a circle with parentheses, which represents a warning for the braking system, mainly indicating brake system failure or low brake fluid level. The braking system should be inspected immediately to avoid accidents.

How Often Should Four-Wheel Brake Maintenance Be Performed?

Four-wheel brake maintenance should be performed every six months or 10,000 kilometers. In addition to wheel alignment, four-wheel maintenance should include brake system and chassis inspections, which should be conducted regularly. The firmness of the brakes is closely related to the safety of the vehicle. Brakes that are too firm can wear out easily, while brakes that are too soft may not provide effective stopping power. Prolonged use of brakes can also have a certain impact on the braking system. If the four-wheel braking is unbalanced during braking, it is usually a sign of an issue with the brake calipers. This may not be very noticeable at first, but over time, it can lead to serious braking problems.

What does car airbag mean?

Car airbag refers to the safety airbag, which is a passive safety protection measure in vehicles. The airbag can evenly distribute the impact force across the head and chest, preventing fragile passengers from directly colliding with the car body, thereby significantly reducing the likelihood of injury. Airbags are indeed effective in protecting passengers during frontal collisions. Even if seat belts are not fastened, the anti-collision airbags are sufficient to effectively reduce injuries. In vehicles equipped with airbags, the severity of passenger injuries can be reduced by up to 64% during frontal collisions, even when 80% of the passengers are not wearing seat belts. As for collisions from the side and rear seats, the protection still relies on the function of seat belts.
