Why does the ABS warning light stay on after installation on a motorcycle?

The reason why the ABS warning light stays on after installation on a motorcycle may be due to faults in components such as the wheel speed sensor, ABS wiring, ABS pump, pressure regulating solenoid valve, or the ABS computer. How ABS works: During braking, the ABS quickly determines the wheel lock-up state based on speed signals from each wheel speed sensor, closing the normally open input solenoid valve on the wheel that begins to lock up to maintain braking force. If the wheel continues to lock up, the normally closed output solenoid valve opens, allowing brake pressure on that wheel to rapidly decrease through a direct connection to the brake fluid reservoir, preventing complete wheel lock-up due to excessive braking force. This keeps the braking state at the optimal point (20% slip rate S), achieving the best braking performance and maximum driving safety. The role of ABS: It maximizes the effectiveness of the brakes, reducing 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 excellent steering control. It avoids severe friction between the tires and the ground, reducing tire wear.
