SRS light being on is caused by: 1. Foreign objects around the airbag sensor wiring harness; 2. ECU sensor data reporting errors; 3. The vehicle being parked in a humid environment for a long time or the wiring interface becoming damp during car washing. SRS refers to the Supplemental Restraint System (airbag). If the light is on, it indicates a fault in the airbag or seat belt pretensioner system. The SRS mainly consists of airbag sensors, collision airbags, and electronic control devices, working in conjunction with seat belts to provide effective collision protection for occupants. The driver-side collision airbag is installed in the steering wheel, while the passenger-side collision airbag is usually installed in the dashboard.

What happens to China V vehicles when China VI is implemented?

If the vehicle is China V or China IV, the implementation of China VI will not affect normal road use, as purchased vehicles are subject to the emission standards at the time of purchase. Therefore, as long as the standards are met, the vehicle can continue to be driven. After the implementation of China VI emissions, the resale value of new China V vehicles will be lower than before, increasing the cost of changing cars. The differences between China V and China VI are: 1. Different carbon monoxide emission requirements: China V vehicles have a carbon monoxide content of 1000mg per kilometer; China VI vehicles have a carbon monoxide content of 500mg per kilometer. 2. Different letter representations: China V is represented by V; China VI is represented by VI. 3. Different issuing departments: China V standards were issued by the Ministry of Environmental Protection; China VI standards were issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine.

What are the names of the external structures of a car?

Introduction to the names of a car's external structures is as follows: 1. Car bumper: The car bumper consists of three parts: the outer panel, buffer material, and crossbeam. It not only enhances the vehicle's appearance but also absorbs and mitigates external impacts, protecting the front and rear of the car body. This ensures pedestrian safety during collisions and reduces injuries to passengers even in high-speed impacts, making it an excellent automotive safety device. 2. Car engine hood: While ensuring engine cooling, it provides effective sound insulation, offering a comfortable ride even when the engine is running at high speeds. Additionally, the engine hood protects the motor, battery, and wiring inside the compartment from dust and water. 3. Car fender: Also known as the wing panel, the car fender is located outside the wheel on the car body, serving as a cover component. It helps reduce the drag coefficient during driving based on aerodynamics, significantly improving the car's stability. Moreover, the fender prevents sand, gravel, and mud kicked up by the wheels from splashing onto the undercarriage, thus protecting the car's chassis.
