TC-SST-ECU communicates with various systems (engine control module, shift lever, twin clutch SST control mode switch, and others) to recognize the driver operation, driving condition, malfunction of systems, and others, and performs the corresponding control of TC-SST assembly.

Name	Function content
TC-SST-ECU	Incorporated into the TC-SST assembly. Controls the solenoid valve of valve body based on the driver operations and signals from sensors and ECUs, and performs the engagement and releasing of clutch as well as the gear shifting. By sending and receiving the information on engine torque, engine speed, shifted gear, and others with the engine control module, performs the integrated control of engine and TC-SST assembly.
Engine control module	By sending and receiving the information on engine torque, engine speed, shifted gear, and others with TC-SST-ECU, performs the integrated control of engine and TC-SST assembly.
ETACS-ECU	Transmits the information to TC-SST-ECU of the brake operation and others needed for the vehicle starting and shifting timing. Receives the information from TC-SST-ECU of the current gear, TC-SST assembly malfunction, and others, and sends the information to the combination meter to display the information.
Other ECUs (ASC-ECU, AWC-ECU, and others)	By the communication with ECUs which are relevant to the driving performance, controls the TC-SST assembly to support the normal driving to the circuit driving.
Shift lever	By sending the information to TC-SST-ECU of the driver operations, and shifting mode and drive mode switching/selection, controls the TC-SST assembly corresponding to the operation conditions.
