COMPONENT DESCRIPTION CHART

No.	Component	Description
1.	BCM	BCM controls power distribution system. BCM judges ignition switch position by push-button ignition switch (push switch) and vehicle condition. BCM checks the ignition switch position internally. Refer to "BODY CONTROL SYSTEM : COMPONENT PARTS LOCATION " for detailed installation location.
2.	Stop lamp relay	Stop lamp switch detects that brake pedal is depressed, and stop lamp relay transmits the signal to BCM. Refer to "COMPONENT PARTS LOCATION " for detailed installation location.
3.	Push-button ignition switch	Push-button ignition switch (push switch) is pressed, and transmits the status signal to BCM and IPDM E/R.
4.	CVT shift selector (detention switch)	CVT shift selector (detention switch) detects shift lever status, transmits detention switch signal to BCM. Refer to "SHIFT LOCK SYSTEM : COMPONENT PARTS LOCATION " for detailed installation location.
5.	Transmission range switch	Transmission range switch detects shift position P or N, transmits P/N position signal to BCM. Refer to "CVT CONTROL SYSTEM : COMPONENT PARTS LOCATION " for detailed installation location.
6.	IPDM E/R	IPDM E/R detects push-button ignition switch (push switch) status, and transmits push-button ignition switch status signal (CAN) to BCM. IPDM E/R receives ignition relay (IPDM E/R) control signal and ignition switch ON signal (CAN) from BCM, and controls ignition relay (built in IPDM E/R) Refer to "IPDM E/R : COMPONENT PARTS LOCATION " for detailed installation location.
7.	Blower relay (built in fuse block)	Blower relay is controlled by BCM. Blower relay supplies the ignition switch ON power supply or the ignition switch ON signal to air conditioning system when ignition switch is turned ON. BCM compares status of blower relay control signal and ignition switch position judged by BCM.
8.	Accessory relay (built in fuse block)	Accessory relay is controlled by BCM. Accessory relay supplies the accessory power supply or the ignition switch ACC signal to each ECU when ignition switch is turned ACC or ON. BCM compares status of accessory relay control signal, and ignition switch position judged by BCM.
9.	Ignition relay (built in fuse block)	Ignition relay is controlled by BCM. Ignition relay supplies the ignition switch ON power supply or the ignition switch ON signal to each ECU and system when ignition switch is turned ON. BCM compares status of ignition relay control signal and ignition switch position judged by BCM. BCM monitors the ignition relay operating status by the ignition relay feedback signal.
