1	ICC steering switch	*	*			ICC steering switch allows the ON/OFF of the intelligent cruise control and the settings of a vehicle speed and distance between vehicles. ICC steering switch signal is transmitted to ECM. ECM transmits the signal to the ADAS control unit via CAN communication.
2	Combination meter (Information display, IBA OFF indicator lamp, buzzer)	*	*	*	*	Performs the following operations using the signals received from the ADAS control unit via the CAN communication: Displays the ICC system operation status using the meter display signal. Illuminates the ICC system warning lamp using the ICC warning lamp signal. Illuminates the IBA OFF indicator lamp using the IBA OFF indicator lamp signal. Operates the buzzer (ICC warning chime) using the buzzer output signal.
3	ICC brake hold relay	*		*		ICC brake hold relay activates the stop lamp by ICC brake hold relay drive signal (stop lamp drive signal) outputted by the ADAS control unit
4	ABS actuator and electric unit (control unit)	*	*	*	*	ABS actuator and electric unit (control unit) transmits the vehicle speed signal (wheel speed), stop lamp signal and VDC/TCS/ABS system operation condition to ADAS control unit via CAN communication. ABS actuator and electric unit (control unit) controls the brake based on a brake fluid pressure control signal received from the ADAS control unit via CAN communication.
5	ICC sensor	*	*	*	*	ICC sensor detects light reflected from a vehicle ahead by irradiating laser forward and calculates a distance from the vehicle ahead and a relative speed, based on the detected signal. ICC sensor transmits the presence/absence of vehicle ahead and the distance from the vehicle to ADAS control unit via ITS communication.
6	TCM	*	*			TCM transmits the signal related to CVT control to ADAS control unit via CAN communication.
7	ECM	*	*	*	*	ECM transmits the accelerator pedal position signal, ICC brake switch signal, stop lamp switch signal, ICC steering switch signal, etc. to ADAS control unit via CAN communication. ECM controls the electric throttle control actuator based on the engine torque demand received from the ADAS control unit via CAN communication.
8	Stop lamp switch	*	*	*	*	ICC brake switch is turned OFF and stop lamp switch is turned ON, when depressing the brake pedal. ICC brake switch signal is input to ECM. These signals are transmitted from ECM to ADAS control unit via CAN communication. Stop lamp switch signal is input to ECM and ABS actuator and electric unit (control unit). These signals are transmitted from ECM and ABS actuator and electric unit (control unit) to ADAS control unit via CAN communication.
9	ICC brake switch	*	*	*	*
10	Steering angle sensor	*				Measures the rotation amount, rotation speed, and rotation direction of steering wheel, and then transmits them to ADAS control unit via CAN communication.
11	ADAS control unit	*	*	*	*	ADAS control unit calculates a target distance between vehicles and a target speed based on signals received from each sensor and switch to transmit an engine torque command value to ECM and a brake fluid pressure control signal to ABS actuator and electric unit (control unit) via CAN communication. ADAS control unit transmits buzzer output signal to combination meter via CAN communication.
