Why are the three lights for Volkswagen tire pressure, anti-skid, and ABS on?

This situation occurs because the tire pressure of the car is abnormal, causing internal encoding errors in the electronic control device, resulting in a malfunction. You can use a diagnostic tool to read the fault code or go directly to a 4S shop for professional repair. Do not continue driving in this situation as it is very dangerous. There are two scenarios when the steering wheel light, anti-skid light, and tire pressure monitoring light are on: 1. Insufficient tire pressure: This causes a difference in wheel speed, and the system may interpret it as wheel slippage, along with steering deviation, leading to these lights turning on. 2. Dirty engine throttle: Due to a mismatch between the engine's power output and the transmission's torque, it may trigger 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.
Seeing the tire pressure, anti-skid, and ABS lights all illuminated on a Volkswagen car is likely due to a faulty wheel speed sensor. The ABS system relies on it to monitor wheel speed, and once this sensor gets dirty or damaged, all three systems may falsely report faults. Low tire pressure can also trigger the tire pressure light, but if all three lights come on together, it's mostly the sensor acting up. The car should be checked immediately, and driving too fast should be avoided as braking power may weaken, making it prone to skidding at high speeds. Once, a friend of mine ignored it, and the brakes failed, nearly causing an accident. It's recommended to first visit a 4S shop to scan for trouble codes and quickly locate and fix the issue. Regularly check tire pressure before driving to avoid small problems turning into big troubles.
