What does yellow ABS mean?

[LaKendra]

Yellow ABS indicates a fault in the ABS system, which may cause the system to stop functioning. This can result in reduced braking effectiveness, increased braking distance, and poorer handling performance during braking. Therefore, when the ABS light comes on, the fault should be addressed promptly. ABS stands for Anti-lock Braking System, and its function is to automatically control the braking force during vehicle braking, preventing the wheels from locking up and maintaining a state of rolling and sliding. Reasons for the ABS light to illuminate include: 1. The sensing part of the wheel speed sensor being covered by dirt or mud, affecting the sensor's ability to detect the corresponding speed signal, which prevents the ABS computer from determining the speed. Simply cleaning the dirt off the wheel speed sensor and adjusting the gap between the sensor and the signal ring can restore normal operation; 2. A damaged wheel speed sensor will also cause the ABS light to illuminate, requiring the sensor to be replaced; 3. Loose connections in the ABS wiring or internal faults in the ABS pump can also cause the ABS light to illuminate, requiring a comprehensive inspection to diagnose the issue.
