	ENGINE RPM [rpm]	x	Indicates engine speed read by ICC unit through CAN communication (ECM transmits engine speed through CAN communication).
	MAIN SW [ON/OFF]	x	Indicates [ON/OFF] status as judged from steering switch signal (ECM transmits steering switch signal through CAN communication).
	SET/COAST SW [ON/OFF]	x	Indicates [ON/OFF] status as judged from steering switch signal (ECM transmits steering switch signal through CAN communication).
	CANCEL SW [ON/OFF]	x	Indicates [ON/OFF] status as judged from steering switch signal (ECM transmits steering switch signal through CAN communication).
	RESUME/ACC SW [ON/OFF]	x	Indicates [ON/OFF] status as judged from steering switch signal (ECM transmits steering switch signal through CAN communication).
	IDLE SW [ON/OFF]	x	Indicates [ON/OFF] status of idle switch read by ICC unit through CAN communication (ECM transmits ON/OFF status through CAN communication).
TCM	VHCL SPD AT [km/h] or [mph]	x	Indicates vehicle speed calculated from AT vehicle speed sensor by ICC unit through CAN communication (TCM transmits AT vehicle speed sensor signal through CAN communication).
	GEAR [1, 2, 3, 4, 5]	x	Indicates AT gear position read by ICC unit through CAN communication (TCM transmits gear position through CAN communication).
	D RANGE SW [ON/OFF]	x	Indicates [ON/OFF] status of "D" position read by ICC unit through CAN communication (TCM transmits ON/OFF condition of "D" position through CAN communication).
	NP RANGE SW [ON/OFF]	x	Indicates PNP switch signal read by ICC unit through CAN communication (TCM transmits PNP switch signal through CAN communication).
VDC/TCS/ABS control unit	VHCL SPEED SE [km/h] or [mph]	x	Indicates vehicle speed calculated from wheel sensor by ICC unit through CAN communication (VDC/TCS/ABS control unit transmits wheel speed sensor signal through CAN communication).
Brake pressure sensor	PRESS SENS [bar]		Indicates brake fluid pressure value calculated from signal voltage of pressure sensor.
Release switch	RELEASE SW NO [ON/OFF]		Indicates [ON/OFF] status as judged from release switch signal. ON when brake is depressed. OFF when brake is not depressed.
Release switch	RELEASE SW NC [ON/OFF]		Indicates [ON/OFF] status as judged from release switch signal. ON when brake is not depressed. OFF when brake is depressed.
ICC brake switch	BRAKE SW [ON/OFF]		Indicates [ON/OFF] status as judged from ICC brake switch signal.
Stop lamp switch	STOP LAMP SW [ON/OFF]		Indicates [ON/OFF] status as judged from stop lamp switch signal.
Front wiper motor	WIPER SW [OFF/LOW/HIGH]		Indicates wiper [OFF/LOW/HIGH] status.
Turn signal	TURN SIGNAL [OFF/LH/RH LH/RH]		Indicates turn signal [OFF/LH/RH LH/RH] status.
