What to Do When the ABS Light on the Car Dashboard Comes On?
1 Answers
Clean the dirt on the vehicle speed sensor and adjust the gap between the vehicle speed sensor and the signal ring to restore normal operation. Alternatively, check the wiring connections and reconnect any loose ones. How ABS Works: During braking, the 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 up, and keeps the braking force unchanged. 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 completely 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 effect and the safest driving. 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.
