ABS with Roll Stability Control (RSC®) and traction control

WARNING: This page is about a different variant/trim than selected.

ABS with Roll Stability Control (RSC®) and traction control consists of the following components:

ABS module
HCU (LH side of the engine compartment, behind the degas bottle)
Front wheel speed sensor
Front wheel speed sensor ring (press fit onto the brake disc)
Rear wheel speed sensor
Rear wheel speed sensor ring (press fit onto the brake disc)
Steering wheel rotation sensor (attached to the steering column)

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 RSC® system utilizes the same components as the ABS and the traction control systems and also monitors the steering wheel rotation sensor and the Restraints Control Module (RCM) to assist in stabilizing the vehicle during abrupt maneuvers.
