What is a ABS Pump?
ABS units have a pump that helps maintain proper pressure in the hydraulic brakes. The ABS ECU module receives input from wheel speed sensors to detect wheel slip and sends a signal to hydraulic valves to release pressure to prevent slip. When this happens, the pump in the ABS unit is used to restore the pressure lost in the brake system. The ABS controller regulates the action of the pump to ensure optimum pressure and minimize slippage.

Symptoms of a failed ABS Pump.
Fortunately, there are some signs you can look out to detect possible problems with your ABS pump.
◆ ABS Warning Light or Engine Light
: A common sign is the ABS warning light or check engine light on the dashboard. Typically, an orange ABS light indicates a pump problem that needs attention. On older vehicles, the check engine light may come on, indicating a potential problem with the ABS system.
◆ Unresponsive Brake Pedal
: Another indicator of a faulty ABS pump is an unresponsive brake pedal. If you notice that your brake pedal is not as responsive as it used to be, or takes longer to depress, it could be a sign of a pump failure. It is important to seek service as soon as possible to avoid a potentially dangerous situation where the brake pedal becomes completely unresponsive.
◆ Harder Braking
: If your brake pedal requires more force than usual to apply the brakes, or if your brakes lock up during normal driving, this is another sign that there may be a problem with the ABS pump. If you experience this problem, it is crucial to seek professional help, especially if you notice strange clicking noises.
◆ Speedometer showing wrong speed
: Finally, a malfunctioning speedometer showing the wrong speed or reading 0 MPH may also indicate a problem with the ABS pump. While this problem usually accompanies the ABS warning light or check engine light, even if the dashboard light doesn't come on, you should still take your car to a professional for diagnosis.
