As more youngsters are fascinated by sports cars, Ford Mustangs have become their first choice for its styling look and outstanding performance. However, what keeps people going to Ford dealers is more than just the appearance of the sports car. As performance cars, Mustangs are equipped with standard air bags, three point seat belts and many other safety features that provide the driver and the passengers with maximum protection, but more importantly, they are built with standard Anti-lock Braking System (ABS) that helps the driver steer and achieve the maximum braking effort in case of wheels locking up and vehicle skidding.
On a 2003 mustang, Anti-lock Braking System is mainly made up of an ABS Module, four wheel speed sensors, a Hydraulic Control Unit (HCU), and the associated wirings. The input components, the wheel speed sensors, are electromagnetic devices that generate alternating current (AC) by the rotating toothed rings on each wheel as the wheels spin (aa1car.com). In the form of sine waves, the signals are sent to the ABS control module where they are analyzed and a decision as to whether ABS should be activated is made. The other major contributing to the functioning of the ABS module is the brake pedal switch, which is located near the brake pedal. It senses whether there is pressure applied to the brake pedal at the time in case of faulty ABS activation (Erjavec, Restoule & Playter, AUTOMOTIVE TECHONOLOGY – FIRST CANADIAN EDITION). If the data tells the ABS control module that one or more wheels are traveling too fast and about to lock up during hard braking, the control module will send a signal to the actuator, the hydraulic control unit to carry out the order of deactivating the brake system temporarily in order to maintain the most traction. The HCU is a hydraulic system mounted to the master cylinder that regulates the flow of hydraulic pressure during the ABS activation. There are two...
