AYC (Active Yaw Control)	Stability control. Prevents oversteering and understeering with active braking.
BA (Brake Assistance)	Brake assistance. Boosts braking force in case of sudden heavy braking. Brake assistance is electronic for vehicles with DSTC, mechanical for others.
EBD (Electronic Brake Distribution)	Electronic distribution of braking force. Distributes braking force between front and rear brakes.
SC (Stability Control)	Stability control. Reduces engine torque to obtain increased lateral stability when the wheels spin at speeds from 0 km/h to top speed.
TC (Traction Control)	Traction control. Brakes spinning wheel from 0 km/h - top speed.
RSC (Roll over Stability Control)	Monitors the car's inclination angle and acts on the brakes if the car is at risk of rolling over.
HDC (Hill Descent Control)	Helps the driver brake the car when driving "off-road" without the driver activating the brake pedal.

System	Description
ABS (Anti-lock Braking System)	Anti-lock braking. Includes the functions ABS and EBD.
DSTC (Dynamic STC)	Dynamic stability and traction control. Includes the functions ABS, EBD, SC, TC and AYC.
STC (Stability and Traction Control)	Traction and stability control. Includes the functions ABS, EBD, SC and TC.
TRACS (Traction Control System)	Traction control system for four-wheel drive cars. Includes the functions ABS, EBD and TC.

Other abbreviations	Description
BCM (Brake Control Module)	Name of control module for brake system (BCM). Includes functions such as ABS, AYC, EBA, EBD, SC, TC and RSC.
CAN (Controller Area Network)	Standardized protocol for serial communication between control modules.
