The anti-lock braking system in your vehicle is a safety feature found in all modern vehicles, and is designed to prevent skidding and wheel locking by using pulse braking. Pulsing the brakes instead of locking the wheels allows your tires to maintain traction while braking. ABS also decreases stopping distance while increasing vehicle control, especially when braking on slippery, wet, or low-traction surfaces. In most modern vehicles, ABS is an electronic system and is supplied with power through an electronic relay. The ABS relay sends power to the ABS control module and throughout the rest of the system to keep it operating when your vehicle is turned on and driving. Like all relays, the ABS relay is designed to open and close the circuit to deliver power to the ABS module while the ignition is in the "Run" position. All relays are subject to wear or damage with time, and this may prevent them from opening and closing as necessary. If your ABS relay is no longer closing the circuit, it may prevent your ABS from working due to an inactive control module. You may experience locked wheels when braking, or an active ABS light alerting you to a problem. ABS warning lights can be caused by a blown ABS relay or fuse, or may signal control module failure or a problem with one of the wheel speed sensors in the system. If you suspect your ABS relay is damaged or the fuse is blown, inspect your ABS system and its relay. Once you've determined the source of the problem, shop the selection of ABS relays, ABS modules, vehicle speed sensors, and more at O'Reilly Auto Parts to complete your repair.
