What to Do When the ABS Light Comes On?

[Pires]

Clean the dirt on the vehicle speed sensor and adjust the gap between the vehicle speed sensor and the signal ring to restore normal function. Alternatively, check the connection points of the wiring and reconnect any loose ones. How ABS Works: During braking, ABS quickly determines the wheel lock-up state based on the speed signals from each wheel speed sensor. It closes the normally open input solenoid valve on the wheel that is starting to lock up, keeping the braking force constant. If the wheel continues to lock up, the normally closed output solenoid valve is opened, causing the braking pressure on that wheel to drop rapidly due to the direct connection to the brake fluid reservoir, preventing the wheel from fully locking up due to excessive braking force. This keeps the braking state at the optimal point (slip ratio S of 20%), ensuring the best braking performance and maximum driving safety. Functions of ABS: Maximize the effectiveness of the brakes, reducing braking time and distance. Effectively prevent vehicle skidding and fishtailing during emergency braking, ensuring good driving stability. Allow steering during emergency braking, providing good steering control. Avoid severe friction between the tires and the ground, reducing tire wear.
