SYSTEM DESCRIPTION FUNCTION DESCRIPTION (a) ABS (Anti-lock Brake System) (1) The ABS helps prevent the wheels from locking when the brakes are applied firmly or when braking on a slippery surface. (b) EBD (Electronic Brake force Distribution) (1) The EBD control utilizes ABS, and performs proper brake force distribution between the front and rear wheels in accordance with driving conditions. When braking while cornering, it also controls the brake forces of the right and left wheels, helping to maintain vehicle stability. (c) BA (Brake Assist) (1) The primary purpose of the brake assist system is to provide auxiliary brake force to assist the driver if the driver cannot generate a large enough brake force during emergency braking, thus helping to maximize the brake performance of the vehicle. (2) If the brake booster malfunctions and the skid control ECU (brake actuator assembly) judges that the brake pedal force applied by the driver is not sufficient to ensure adequate braking force, brake assist is used to enhance the braking force. (d) TRAC (Traction Control) (1) The TRAC system helps prevent the drive wheels from slipping when the driver depresses the accelerator pedal excessively when starting off or accelerating on a slippery surface. (e) VSC (Vehicle Stability Control) (1) The VSC system helps prevent the vehicle from slipping sideways as a result of strong front or rear wheel skid during cornering. (f) Hill-start Assist Control (1) When starting uphill, this control maintains the brake hydraulic pressure to the 4 wheels, in order to momentarily help to prevent the vehicle from descending backward. (g) Trailer Sway Control (1) If the vehicle is towing a trailer with an inappropriate hitch load, trailer sway could be caused by crosswinds, imbalance caused by the load, or the driver's steering. Trailer sway control reduces trailer sway by controlling the engine output and the braking of each wheel. (h) AUTO LSD (Auto Limited Slip Differential) (1) For 2WD vehicles and 4WD vehicles in 2H mode, the AUTO LSD will operate with the VSC OFF switch (traction control switch) on (TRAC OFF or AUTO LSD mode) and the accelerator pedal depressed. The AUTO LSD system is used to restrain brake pressure and reduce differential movement, thus transmitting drive torque to the other drive wheel to ensure startability under the following conditions:
HINT: Depressing the brake pedal cancels control of the AUTO LSD system. FUNCTION OF COMPONENTS
