C0061 fault code indicates a malfunction in the lateral acceleration sensor. Here is an introduction to the lateral acceleration sensor: 1. In the Electronic Stability Program (ESP), the lateral acceleration sensor is used to measure the vehicle's lateral acceleration. Lateral acceleration refers to a key parameter related to the centrifugal force generated when the vehicle is turning. 2. Vehicle lateral acceleration refers to the acceleration perpendicular to the driving direction, which is caused by centrifugal force during turning maneuvers. Essentially, it represents the tendency of the car to be "thrown outward." The greater this acceleration, the more likely the vehicle is to deviate from its intended path. 3. The measurement principle of the lateral acceleration sensor is based on a deflection-extended mass system with capacitive detectors. Voltage is supplied by the ESP control unit. During turns, the generated lateral acceleration causes the mass element to overcome the force of the elastic rod, moving from its neutral position to a position corresponding to the lateral acceleration value. 4. Acceleration refers to the rate of change in velocity. Acceleration does not equate to speed. The function of this sensor is to measure acceleration, transmit the signal to the ECU for analysis, and then the ECU sends signals to relevant actuators to adjust the vehicle's driving state.

Is it no longer necessary to display the vehicle insurance decal?

Vehicle insurance decals no longer need to be displayed. Here are the details about the digitization of inspection decals: 1. Electronic certificate: For vehicles eligible for the 6-year exemption from on-site inspection, which require renewal of the inspection decal every 2 years, you can now apply for an electronic certificate online. The electronic certificate holds the same validity as the paper version, and vehicles that have obtained it no longer need to display the paper decal. 2. Application method: You can apply for the electronic inspection certificate through the "Internet-based Comprehensive Traffic Safety Service Platform" or the "Traffic Management 12123" mobile app. In the "Traffic Management 12123" app, simply click on the "Exempt Vehicle Application for Inspection Decal" option under the "Service Center" section to complete the process. The traffic management department will uniformly generate the electronic inspection certificate, which can be downloaded and used directly online.

Why is it not recommended to replace the original car bumper?

It is not recommended to replace the original car bumper because aftermarket products are of inferior quality compared to the original and may have color discrepancies. Below is a detailed introduction to the car bumper. Bumper Composition: The front and rear bumpers of a car are made of plastic. Typically, 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. Bumper Function: The car bumper is a safety device designed to absorb and mitigate external impacts, protecting the front and rear of the vehicle. In addition to maintaining its primary protective function, modern bumpers also aim for harmony and unity with the car's overall styling and pursue lightweight construction.

Is There a Difference Between Setting 1 and 4 on a Car's Air Conditioning?

There is a difference between setting 1 and 4 on a car's air conditioning. The specific differences between setting 1 and 4 on a car's air conditioning are as follows. Fuel consumption: It will increase fuel consumption, but not significantly. This is because the compressor is driven by the engine's belt, and its speed is only related to the engine. However, lowering or raising the setting by one level only changes the speed of the blower fan inside the car. A higher blower speed consumes more electricity, and the car's electricity can only be generated by consuming gasoline. Power: Generally, the power of a car's air conditioning compressor is not adjustable; it only has two states: on or off. Setting the air conditioning to level 4 will feel cooler than level 1, but this is only due to the difference in heat exchange efficiency, not because the compressor works at a higher power at level 4 compared to level 1.

What is the maintenance and replacement cycle for the Trumpchi GA4?

The Trumpchi GA4 vehicle generally requires maintenance every 5,000 kilometers. If the car is not used frequently and does not reach 5,000 kilometers in a year, it is recommended to perform maintenance every six months. This is because fluids such as engine oil, coolant, and brake fluid have a shelf life and can deteriorate if not used for a long time. Owners can also refer to the vehicle's user manual (maintenance manual), which provides detailed instructions. Follow the maintenance schedule specified in the manual. The replacement intervals for car parts are as follows: 1. Air filter: Replace every 20,000 kilometers. 2. Fuel filter: Replace every 10,000 kilometers. 3. Cabin air filter: Replace every 20,000 kilometers. 4. Brake fluid: Replace every 40,000 kilometers. 5. Spark plugs: Replace every 50,000 kilometers. 6. Timing chain: Replace every 80,000 kilometers. 7. Antifreeze: Replace every 20,000 kilometers. 8. Brake fluid: Replace every 40,000 kilometers.

What are the components of a tire?

Tire structure consists of tread, sidewall, shoulder, nylon cap ply, steel belt, carcass ply, and inner liner. Automobile tires are one of the important components of a vehicle, directly contacting the road surface and working together with the suspension system to absorb shocks during driving, ensuring good ride comfort and smoothness. They also maintain excellent adhesion between the wheels and the road surface, improving traction, braking, and off-road capability while bearing the vehicle's weight. The crucial role of tires in automobiles is increasingly being recognized. Passenger car wheels generally use radial tires. Radial tire specifications include width, aspect ratio, inner diameter, and speed rating symbols. For example, a tire marked 195/60R14 indicates a width of 195 millimeters between the sidewalls, an aspect ratio of 60, "R" standing for RADIAL (indicating a radial tire), and 14 being the inner diameter in inches. Some tires also display speed rating symbols represented by letters P, R, S, T, H, V, Z indicating respective speed limits. Tire maintenance: Develop a habit of regular tire inspections; Maintain proper tire pressure; Routinely clean debris from tread grooves; Regularly check tire wear conditions; Pay attention to road conditions while driving.
