Description of functions

Anti-lock brake system (ABS)
1. Helps prevent wheel lock when the brakes are applied quickly or on a slippery road surface.
Electronic brake distribution control (EBD)
1. The EBD control uses the ABS to control distribution of brake force to front and rear wheels depending on driving conditions. Also, the system controls application of braking force to right and left wheels to stabilize vehicle motion while cornering.
Brake assist (BA)
1. The main purpose of brake assist is to provide additional braking force for a driver who cannot depress the brake pedal hard when hard braking is needed. With this assist, braking performance of the vehicle is assured.
Traction control (TRC)
1. Controls slipping of driving wheels when the driver depress the accelerator pedal too far to starts or accelerates the vehicle on a slippery surface.
Vehicle stability control
1. Controls vehicle skidding sideways when vehicle is apt to understeer or oversteer excessively while cornering.
Parts function

Parts		Function
Brake actuator ASSY	Skid control ECM	Based on signals from sensors and switches, identifies driving conditions and sends brake control signal to the brake actuator ASSY.
	Master cylinder pressure sensor	Detects master cylinder pressure.
	Pump motor	Activates the pump in the brake actuator ASSY.
	Solenoid valve	The hydraulic circuit has two master cylinder cut solenoid valves, two intake solenoid valves, four retaining solenoid valves, and four relief solenoid valves. To control a hydraulic pressure applied to the wheel cylinder, switches the hydraulic circuits based on the signal from the skid control during operation of the brake control system.
	Yaw rate and acceleration sensors	The yaw rate sensor detects the vehicle yaw rate. The acceleration sensor detects longitudinal acceleration and lateral acceleration of the vehicle.
Skid control ECM	ABS motor relay	Provides power supply to the pump motor.
Skid control ECM	ABS solenoid relay	Provides power supply to the solenoid valve.
Speed sensor		Detects four wheels and speed of each wheel.
Console switch ASSY	Vehicle stability control OFF switch	Normal mode, TRC OFF mode, or Vehicle stability control OFF mode is selectable.
Console switch ASSY	TRACK switch	Either normal mode or TRACK mode is selectable.
Stop light switch ASSY		Detects the brake pedal signal issued when the pedal is depressed.
Main body ECM (multiplex network body ECM)		Sends parking brake switch signal to the skid control ECM.
Parking brake switch ASSY		Detect the condition of the parking brake pedal.
ECM		Sends signals including the accelerator pedal opening angle signal and the engine speed signal to the skid control ECM. Controls the engine output based on the signal received from the skid control ECM.
TCM		Sends gear position signal to the skid control ECM.
Steering angle sensor		Detects the steering direction of a steering wheel and the steering wheel angle.

Parts		Function
Combination meter ASSY	ABS warning light	When the skid control ECM detects an ABS malfunction, it illuminates to let the driver know the malfunction occurrence.
	Brake warning light	When the skid control ECM detects an EBD malfunction or a brake system malfunction, it illuminates to let the driver know the malfunction occurrence. When the brake fluid level is low, it illuminates to let the driver know the condition. When the parking brake is operated, it illuminates to let the driver know the operation.
	TRC OFF indicator light	When the TRC OFF mode is selected, it illuminates to let the driver know the selection.
	Vehicle stability control OFF indicator light V	When the Vehicle stability control OFF mode or Vehicle stability control SPORT mode is selected, it illuminates to inform the driver of the selection.
	TRACK indicator light	When the TRACK mode is selected, it illuminates to inform the driver of the selection.
	Slip indicator light	When TRC control or Vehicle stability control is taking place, it flashes to inform the driver that the control is active. When the skid control ECM detects a TRC malfunction and/or a Vehicle stability control malfunction, it illuminates to inform the driver of the malfunction occurrence.
