No.	Component	Description
1.	Intelligent Key Unit	Intelligent Key Unit controls power distribution system. Intelligent Key Unit judges ignition position and vehicle condition. Intelligent Key Unit checks ignition position internally.
2.	Stop lamp switch	Stop lamp switch detects that the brake pedal is depressed and transmits the signal to the BCM.
3.	Transmission range switch	The transmission range switch transmits P (park) and N (neutral) signals to the IPDM E/R.
3.	Transmission range switch
4.	Starter relay	The starter relay is controlled by the BCM. The starter relay supplies power to the starter cut relay in the IPDM E/R.
5.	IPDM E/R	IPDM E/R detects push-button ignition switch status, and transmits ignition switch status signal (CAN) to BCM. IPDM E/R receives ignition relay-1 (IPDM E/R) control signal and ignition switch ON signal (CAN) from BCM, and controls ignition relay-1 (built into IPDM E/R)
6.	BCM	BCM controls power distribution system. BCM judges ignition position and vehicle condition. BCM checks ignition position internally.


7.	Push-button ignition switch	Push-button ignition switch (push switch) is pressed (ON), and transmits status signal to Intelligent Key Unit and IPDM E/R.
8.	CVT shift selector (park position switch)	The CVT shift selector (park position switch) sends the park position switch signal to the Intelligent Key Unit.
9.	Ignition relay-2 (in fuse block)	Ignition relay-2 is controlled by Intelligent Key Unit. Ignition relay-2 supplies ignition ON power supply or ignition ON signal to each ECU and system when ignition is turned ON. Intelligent Key Unit compares status of ignition relay-2 control signal and ignition position judged by Intelligent Key Unit. Intelligent Key Unit monitors ignition relay-2 operating status by ignition relay-2 feedback signal.
10.	Front blower motor relay (in fuse block)	Front blower motor relay is controlled by Intelligent Key Unit. Front blower motor supplies ignition ON power supply or ignition ON signal to air conditioning system when ignition is turned ON. Intelligent Key Unit compares status of front blower motor relay control signal and ignition position judged by Intelligent Key Unit.
11.	Accessory relay-1 (in fuse block)	Accessory relay-1 is controlled by BCM. Accessory relay-1 supplies accessory power supply or ignition ON signal to each ECU when ignition is turned ON. BCM compares status of accessory relay-1 control signal, and ignition position judged by BCM.
