The described Anti-lock Brake System (ABS) is used to prevent vehicle's wheels from locking by actively modulating the brake line pressure for every wheel, which allows for the maintainance of steerability, directional stability, and the optimal amount of deceleration during hard braking on most road surfaces. At the right rear corner of the engine compartment, total of five items such as electric hydraulic pump and two solenoid valves for each wheel are still included in the actuator assembly which is used to control hydraulic pressure during the ABS. At the wheels, speed sensors create a sine wave current as the sensor rotors spin and the ABS control module then amplifies, samples and digitizes this analog voltage signal to obtain the wheel speed. The control unit is one of the main parts of the system and controls the hydraulic line pressure through being the brain of the system that receives information from the wheel speed sensors to avoid wheel lock while at the same time, it checks for a malfunction, even during normal road use. ABS light comes on for a second after starting the engine and should go out if the engine is running properly, the ABS performs a self-test whenever the vehicle speed surpasses four mph; often, this sounds like a normal metallic noise. When a problem is identified, the ABS light will not go off, and a specific code of the problem will be written to the control unit.
