Why is the car ABS warning light on?

Reasons for the car ABS warning light being on: The ABS anti-lock braking system has malfunctioned, most likely due to a faulty sensor in the anti-lock system, a broken signal line, or the failure of the anti-lock function. It is best to promptly visit a 4S shop for inspection and repair. The role of ABS: It prevents loss of steering control and wheel skidding during emergency braking, ensuring that the wheels do not lock up during braking. This prevents the tires from rubbing against the ground at a single point, thereby increasing friction and achieving a braking efficiency of over 90%. Additionally, it reduces brake wear and extends the service life of brake drums, discs, and tires by up to twice as long.
I've been driving for over 20 years and encountered the ABS light coming on several times. It usually indicates an issue with the anti-lock braking system, most commonly due to dirty or damaged wheel speed sensors. The wheel speed sensors are located near the wheel hubs. If there's excessive mud on the road or impact damage, they may read data incorrectly, triggering the light. It could also be caused by loose electrical connections or a malfunction in the ABS module itself, preventing the controller from receiving correct signals. Last time my car's light came on, inspection revealed a small stone stuck on the sensor - cleaning it fixed the issue. However, if it's a module problem, replacement parts are necessary. ABS is crucial; when the light is on, it means wheels may lock up during braking on slippery surfaces, greatly increasing the risk of skidding and loss of control - extremely dangerous. My advice: don't delay when you see the light. Immediately visit a repair shop to scan for trouble codes and identify the specific cause before fixing. Safety first - don't risk major accidents to save small money.
