Anti-Lock Control Anti-Lock Brake System (ABS) with Traction Control and Roll Stability Control (RSC) The ABS consists of the following components:
The ABS prevents wheel lock-up by monitoring the wheel speed sensors and actuating the valves in the HCU which modulates the brake pressure to the brake calipers. 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 rotation sensor and the stability control sensor cluster to assist in stabilizing the vehicle during abrupt maneuvers. The front wheel speed sensor rings are integral to the front hub and bearing assemblies. The rear wheel speed sensor rings are integral to the rear half shafts.
