ABS Control Module Replacement
What is an ABS control module?
The anti-lock braking (ABS) control module is a computer that constantly receives information from the wheel speed sensors, and uses that data to prevent the vehicle from losing stability and traction in case the need arises.
How does the ABS control module work?
The ABS system is designed to keep the brakes from locking up on one of the wheels while the vehicle is in motion by quickly engaging and disengaging the brakes in rapid succession until the vehicle is out of harm's way. The ABS control module is the brain of this system, and is physically attached to the brake lines to control the amount of pressure that is being applied when the driver depresses the brake pedal.
A failing ABS control module can turn on the ABS light and disable the Traction and Stability Control Systems (if equipped). In some cases, the speedometer will stop working and the Check Engine Light will come on.
A malfunctioning ABS control module can cause abnormal braking behavior when braking at low speeds.
