2000 Chevrolet Blazer - ABS Speed Sensor Wire Harness

The anti-lock braking system (ABS) monitors and controls the vehicle's brakes so they can automatically apply or release brake pressure to maintain optimal traction and stability. The ABS wheel speed sensor wire harness sends signals from the sensor to the engine control module about the wheels' rotational speed. The sensor triggers the control module to release the brake pressure if the vehicle's brakes lock up, allowing for a more controlled stop.
