No.	Component	Function
(1)	EVAP canister purge volume control solenoid valve	"EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE "
(2)	Transmission range switch	The transmission range switch is installed to upper part of transaxle case. ECM detects the selector lever position because the continuity of the transmission range switch line (the ON) exists.
(3)	ECM	"ECM "
(4)	Refrigerant pressure sensor	"REFRIGERANT PRESSURE SENSOR "
(5)	Battery current sensor (with battery temperature sensor)	"BATTERY CURRENT SENSOR (WITH BATTERY TEMPERATURE SENSOR) "
(6)	IPDM E/R	IPDM E/R control the internal relays and the actuators. Refer to "RELAY CONTROL SYSTEM: SYSTEM DESCRIPTION ". When CAN communication with ECM is impossible, IPDM E/R performs fail-safe control. Refer to "FAIL SAFE ".
(7)	Mass air flow sensor (with intake air temperature sensor)	"MASS AIR FLOW SENSOR (WITH INTAKE AIR TEMPERATURE SENSOR) "
(8)	Intake manifold runner control valve actuator	"INTAKE MANIFOLD RUNNER CONTROL VALVE "
(9)	Electric throttle control actuator (with built in throttle position sensor and throttle control motor)	"ELECTRIC THROTTLE CONTROL ACTUATOR "
(10)	EVAP service port	When perform the EVAP leak check, positive pressure is delivered to the EVAP system through the EVAP service port. Refer to "INSPECTION ".
