What is an ABS Wiring Diagram?
ABS wiring diagrams are diagrams that show the wiring configuration of an Anti-Lock Braking System (ABS). ABS is a type of Brake Control System (BCS) that helps to reduce wheel lockup and skidding during hard braking. ABS wiring diagrams show the location of each component on the ABS system, as well as the wiring connections between the ABS components. They are also used to troubleshoot and diagnose problems with the ABS system.
How Does the Wabco Trailer ABS System Work?
The Wabco Trailer ABS system works by using a series of sensors to detect when the trailer is in an emergency braking situation. When the ABS system senses a potential wheel lockup, it will quickly apply pressure to the wheel brakes, reducing the risk of skidding and wheel lockup. The Wabco Trailer ABS system also includes other features such as an unload monitoring system, which is designed to help reduce excessive wear and tear on the trailer brakes.
What are the Components of a Wabco Trailer ABS System?

The ECU monitors the inputs from the wheel speed and trailer speed sensors and activates the ABS system as needed. The wheel speed sensor measures the speed of the individual trailer wheels, while the trailer speed sensor measures the overall speed of the trailer. The relay valve is responsible for regulating the pressure of the brake fluid to the individual wheel brakes.
