Anti-Lock Brake System (ABS) and Stability Control: Overview

The ABS and stability control system is comprised of the following subsystems which assist the driver in maintaining control of the vehicle:

• Base ABS
• EBD
• Traction control
• ESC
• RSC®
• Trailer sway control
• Supplemental braking assist
• Supports Adaptive Cruise Control
• Supports Collision Avoidance

The base ABS helps to maintain steering control by preventing the wheels from locking up during hard braking. The base ABS also includes a brake assist function that will provide maximum brake system pressure during a severe braking situation.

The EBD system helps to maintain vehicle control by keeping a balanced braking condition between the front and rear wheels.

The traction control system helps to prevent loss of traction by reducing drive-wheel spin during acceleration.

The trailer sway control system helps maintain vehicle stability while towing a trailer by detecting and aiding in the reduction of conditions that cause trailer sway.

The ESC system helps to prevent skids or lateral slides by activating portions of the base ABS.

The RSC® system helps to prevent excessive vehicle roll by activating portions of the base ABS.

The supplemental braking assist system uses the hydraulic pump motor and HCU to provide additional braking assist in the event of a severe vacuum loss at the brake booster, to maintain the distance gap set by the adaptive cruise control system or to aid in the avoidance of forward collisions.
