Rear Anti-Lock Brake System (RABS) Module: Description and Operation
PURPOSE
The Rear Antilock Brake System (RABS) module continuously monitors the rear wheel speed with a sensor mounted on the rear axle for an
impending rear wheel lockup condition during braking.
The RABS Module will modulate hydraulic pressure to the rear brake cylinders to inhibit rear wheel lockup.
The RABS Module has self-test capabilities much like those in other electronic control systems.
