How to solve the ABS light on the car dashboard?

[ColemanRose]

Clean the dirt on the vehicle speed sensor and adjust the gap between the vehicle speed sensor and the signal gear ring to restore normal operation. Alternatively, check the connection points of the wiring and reconnect any loose connections. How ABS works: During braking, ABS quickly determines the wheel lock-up state based on the speed signals from each wheel speed sensor, closes the normally open input solenoid valve on the wheel that is starting to lock, and keeps the braking force unchanged. If the wheel continues to lock, the normally closed output solenoid valve is opened, and the braking pressure on that wheel rapidly decreases due to the direct connection to the brake fluid reservoir, preventing the wheel from completely locking due to excessive braking force. This keeps the braking state at the optimal point (slip rate S of 20%), achieving the best braking effect and the safest driving. Functions of ABS: Maximize the effectiveness of the brakes, shortening braking time and distance. Effectively prevent vehicle skidding and fishtailing during emergency braking, ensuring good driving stability. Allow steering during emergency braking, ensuring good steering control. Avoid violent friction between the tires and the ground, reducing tire wear.
