What is the reason for the simultaneous illumination of the ABS light and handbrake light in the Buick Excelle?

[VanEvangeline]

The reason for the simultaneous illumination of the ABS light and handbrake light in the Buick Excelle is either an issue with the electrolytic capacitor or a drop in brake fluid level. Issue with the electrolytic capacitor: The module circuit uses electrolytic capacitors instead of solid-state capacitors. Over time, electrolytic capacitors may leak, causing circuit corrosion and short circuits. This problem generally cannot be repaired, but the module can be replaced individually without needing to replace the entire ABS pump assembly. Drop in brake fluid level: Both the ABS light and handbrake light are affected by the brake fluid level inside the car. Once the brake fluid level drops, both lights will illuminate simultaneously. The solution is to add brake fluid to restore it to the normal level. Function of ABS: It maximizes the effectiveness of the brakes, reducing braking time and distance; effectively prevents vehicle skidding and fishtailing during emergency braking, ensuring good driving stability; allows steering during emergency braking, maintaining good steering control; avoids excessive friction between the tires and the ground, reducing tire wear.
