What are the reasons for the simultaneous illumination of the ABS, tire pressure, and anti-skid lights in the Volkswagen Lavida?

The simultaneous illumination of the ABS light, tire pressure light, and anti-skid light in the Volkswagen Lavida may be caused by abnormal tire pressure, a dirty engine throttle, or internal encoding errors in the electronic control unit. Abnormal tire pressure can lead to differences in wheel speed, causing the system to detect wheel slip and steering deviation, which triggers these lights. Adjusting the tire pressure to the normal range can resolve this issue. When the engine throttle is dirty, the power output of the engine may not match the torque of the vehicle's transmission, leading to chassis fault codes. It is recommended to first balance the tire pressure at a tire shop and then inspect the throttle. If it is found to be dirty, clean it promptly. For internal encoding errors in the electronic control unit, a diagnostic tool can be used to read the fault codes, or you can visit a 4S shop for professional repair.
Speaking of the Volkswagen Lavida's ABS, tire pressure, and anti-skid lights all being on, this is a common issue. As someone who has been repairing cars for a long time, I've encountered many cases: the ABS light indicates an anti-lock braking system warning, the tire pressure light alerts to abnormal tire pressure, and the anti-skid light represents an issue with the electronic stability program. All three lights coming on simultaneously is often due to a faulty wheel speed sensor or signal interference, as it provides data to all these systems. The sensor might be clogged with mud, have aged wiring causing a short circuit, or the control unit might receive incorrect signals, leading to a chain reaction. For example, after the wheel hits a bump, the sensor may loosen, causing the system to misinterpret it as abnormal speed or tire pressure changes, triggering the lights. It could also be caused by unstable battery voltage or software errors. Don't ignore it, as the fault affects braking performance and vehicle stability. I recommend first stopping to check the tire pressure and trying a manual reset, but in most cases, a professional diagnostic tool is needed to read the fault codes and address the issue accordingly—such as cleaning the sensor or replacing parts—to ensure driving safety.
