What does the ABS system on a car mean?
2 Answers
The ABS system on a car is an Anti-lock Braking System. The reasons for the ABS light to come on are: 1. The brake fluid in the master cylinder reservoir is too low; 2. There is air in the brake system pipelines; 3. The wheel speed sensor is damaged or there is a fault in the circuit; 4. The wheel speed sensor induction ring is damaged or there are debris between the sensor and the induction ring; 5. The electric return pump relay is damaged; 6. The electric return pump motor is damaged; 7. The solenoid valve relay is damaged or there is a fault in the circuit; 8. The two-position two-way solenoid valve is damaged, or the solenoid valve position in the pressure regulator is incorrect; 9. There is a fault in the ABS ECU power circuit.
The ABS system is the anti-lock braking system in cars, which prevents the wheels from completely locking up during emergency braking. I've been driving for many years and often encounter skidding situations in rainy or snowy weather. If the wheels lock up, the car will lose control like sliding on ice, making it impossible to steer. ABS uses sensors to monitor the speed of each wheel in real-time. When it detects that a wheel is about to lock up, the computer immediately adjusts the hydraulic pump, briefly releasing the brake and then reapplying it to keep the wheels rolling. This allows you to brake while still being able to steer and avoid obstacles. This is especially crucial on wet or icy roads, as it can reduce the likelihood of rollovers or rear-end collisions. Modern cars are generally equipped with ABS as standard, and as an experienced driver, I consider it a core component of passive safety, silently protecting passengers during everyday driving.
