Why are the ABS and brake slip lights of the Volkswagen Lavida on at the same time?
1 Answers
The reasons why the ABS and brake slip lights of the Volkswagen Lavida are on at the same time may be due to faults in the wheel speed sensor, ABS wiring, ABS pump, pressure regulating solenoid valve, ABS computer, and other components. How ABS works: During braking, ABS quickly determines the wheel lock 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, 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 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. The role of ABS: It maximizes the effectiveness of the brakes, shortening braking time and distance. It effectively prevents vehicle skidding and fishtailing during emergency braking, ensuring good driving stability. It allows steering during emergency braking, providing good steering control. It avoids severe friction between the tires and the ground, reducing tire wear.
