Anti-Lock Control

WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The ABS consists of the following components:

Hydraulic control unit (HCU)
Anti-lock brake control module
Front and rear wheel speed sensors
Front and rear wheel speed sensor rings
Stability control sensor cluster
Stability/traction control switch

The ABS prevents wheel lock-up by monitoring the wheel speed sensors and actuating the HCU modulating the brake pressure to prevent wheel lockup. By preventing the wheels from locking up, the driver is able to maintain steering control and stop in the shortest possible distance under most conditions. The traction control system utilizes the same components as the ABS to prevent wheel spin and help maintain vehicle control during acceleration. The roll stability control (RSC) system utilizes the same components as the ABS and the traction control systems and also monitors the steering wheel position sensor and the stability control sensor cluster to assist in stabilizing the vehicle during abrupt maneuvers.
