What is an ABS Electronic Stability Program Fault?
2 Answers
Refers to the Anti-lock Braking System. Below is relevant information about ABS: Introduction: The Anti-lock Braking System, abbreviated as ABS. Its function is to automatically control the braking force during vehicle braking, preventing wheel lock-up and maintaining a state of rolling and sliding (with a slip ratio around 20%), ensuring maximum adhesion between the wheels and the road surface. Classification: ABS control channels are categorized into four-channel, three-channel, two-channel, and single-channel types. Functions: Maximizes braking efficiency, reducing braking time and distance; effectively prevents vehicle skidding and fishtailing during emergency braking, ensuring good driving stability; allows steering during emergency braking, providing excellent steering control.
I've always found it quite annoying when the car's ABS light comes on, mainly because it indicates an issue with the ABS electronic stability system, meaning the anti-lock braking program is malfunctioning. The most common cause is the wheel speed sensor being covered in mud or broken, preventing accurate data transmission when the wheels rotate, leading the system to mistakenly detect skidding. Another possibility is software conflicts or hardware burnout in the control unit, with potential short circuits or open circuits in the wiring, or a blown fuse cutting off the current. In such cases, the wheels are prone to locking up during braking, especially in rainy or snowy conditions, which is particularly dangerous as the braking distance can extend by several meters. My advice is not to delay once the light comes on—take it to a repair shop to check the fault codes. A technician can use a computer to read the codes and pinpoint the issue, and repairs are generally not too expensive.
