The ABS control module is the computer that reads wheel speed sensor data and rapidly pulses the brakes to prevent lockup during hard or slippery-surface braking. A failing module commonly triggers an illuminated ABS warning light, loss of anti-lock function during hard stops, or in some vehicles, a disabled traction control or stability control system that shares the same unit. Browse replacement ABS control modules for cars, trucks, and SUVs to restore proper anti-lock brake function and full braking control.
