Does the ABS yellow light being on affect driving?
1 Answers
When the ABS light in a car is on, it indicates that the anti-lock braking system fault indicator is illuminated, suggesting there may be a fault in the system. It is recommended to use an automotive computer diagnostic tool to check the ABS system and clear the fault codes. If the fault indicator turns off, it indicates an intermittent fault, which is not a major issue. Below are relevant details: 1. ABS Anti-lock Braking System: Sensors installed on the wheels send signals when the wheels are about to lock up. The controller then instructs the regulator to reduce the hydraulic pressure in the wheel's brake cylinder, decreasing the braking torque. After a certain period, the original hydraulic pressure is restored. This cycle repeats continuously (up to 5~10 times per second), keeping the wheels in a rotating state while maintaining maximum braking torque. 2. ABS System Communication Line Fault: Issues such as poor connections or breaks in the ABS system communication lines can also cause the ABS fault light to illuminate. Examples include a short circuit in an ABS sensor power line to ground, low voltage, no voltage in the ABS control unit, or a damaged relay. For such faults, it is necessary to inspect and repair the wiring to clear the ABS fault light.
