What does AAS failure mean?
2 Answers
AAS failure indicates a problem with the vehicle's wheel speed sensor. Here is relevant information about automotive wheel speed sensors: 1. Definition: A wheel speed sensor is used to measure the rotational speed of a vehicle's wheels. 2. Characteristics: All speed sensors can serve as wheel speed sensors, but considering practical factors such as the working environment and space constraints of wheels, commonly used wheel speed sensors mainly include: magnetic wheel speed sensors and Hall-effect wheel speed sensors. 3. Importance: For modern vehicles, wheel speed information is essential. Systems such as Vehicle Dynamic Control (VDC), Electronic Stability Program (ESP), Anti-lock Braking System (ABS), and automatic transmission control systems all require wheel speed information. Therefore, the wheel speed sensor is one of the most critical sensors in modern vehicles.
AAS fault usually refers to a problem with the adaptive air suspension system. As someone who enjoys studying cars, I find such issues quite common in luxury vehicles like Mercedes-Benz and Audi. The adaptive air suspension works by adjusting the vehicle's height using air springs, ensuring a smoother and more comfortable ride. When it malfunctions, the system may experience air leaks or electronic control failures, leading to uneven vehicle height, excessive bouncing, and a boat-like driving sensation. Possible causes include aging or leaking air springs, damaged sensors, or faulty control modules. Professional diagnostic equipment is required to read the fault codes for accurate troubleshooting. Ignoring the issue can shorten the suspension's lifespan, degrade driving comfort, and increase fuel consumption. It's recommended to visit a reliable repair shop for inspection as soon as possible.
