What Causes Both the ABS Anti-Slip and Tire Pressure Lights to Illuminate Simultaneously?
2 Answers
Reason: The issue is caused by a malfunction in the vehicle's electronic control system. Solution: Promptly visit the car's 4S shop or a professional auto repair shop to inspect the vehicle's electronic control system. Using a diagnostic computer to check the electronic control codes will resolve the problem of the ABS light illuminating. Tire Pressure Monitoring Light: The tire pressure monitoring indicator is a yellow symbol featuring an irregular circle with no top seal, four small spikes at the bottom, and an exclamation mark inside. The illumination of this light indicates abnormal tire pressure. There are generally three reasons for abnormal tire pressure: Abnormal Tire Pressure: The system typically alerts when pressure is below 1.8 bar or above 3.0 bar. In such cases, tire inspection and pressure adjustment are necessary. Tire Pressure Monitoring Not Reset: After inflating the tires, if the tire pressure monitoring system is not reset promptly, it continues to record the previous data, causing the tire pressure monitoring light to illuminate. Simply performing a tire pressure reset will resolve this issue. Damaged Tire Pressure Sensor: The tire pressure sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If the sensor is damaged during driving (e.g., by impact), the tire pressure warning light will activate. Damaged sensors must be replaced with new components.
When both the ABS anti-skid and tire pressure warning lights illuminate simultaneously, it typically indicates a system-related fault. One common cause is wheel speed sensor issues: if your wheel speed sensor is dirty or damaged, it cannot detect the wheel rotation speed, triggering the ABS warning. Since the tire pressure system also relies on these sensor data to determine whether a tire is leaking or unbalanced, both warnings may appear together. Another frequent cause is electrical faults, such as a blown fuse—many vehicles use a single fuse for both the ABS and tire pressure modules, so when it fails, multiple warning lights may activate. There could also be a fault in the body control module, which integrates signals from multiple systems; a single malfunction here can affect several systems. Lastly, don’t forget to check the tires themselves: low pressure or a puncture can directly trigger the tire pressure light and indirectly impact the ABS. If you notice any issues, don’t delay—visit a professional shop for diagnosis as soon as possible. Safety comes first.
