POWER DISTRIBUTION SYSTEM REFERENCE CHART

No.	Component	Description
1.	Power switch	Refer to "POWER SWITCH ".
2.	IPDM E/R	IPDM E/R detects power switch (push switch) status, and transmits power switch (push switch) status signal (CAN) to BCM. IPDM E/R receives ignition relay (IPDM E/R) control signal and power switch ON signal (CAN) from BCM, and controls ignition relay (built in IPDM E/R) Refer to "COMPONENT PARTS LOCATION " for detailed installation location.
3.	Stop lamp switch	Stop lamp switch detects that brake pedal is depressed, and transmits the signal to BCM. Refer to "COMPONENT PARTS LOCATION " for detailed installation location.
4.	BCM	BCM controls power distribution system. BCM judges power supply position by power switch (push switch) and vehicle condition BCM checks the power supply position internally. Refer to "BODY CONTROL SYSTEM : COMPONENT PARTS LOCATION " for detailed installation location.
5.	Accessory relay	Accessory relay is controled by BCM. Accessory relay supplies the accessory power supply or the power switch ACC signal to each ECU when power switch is turned ACC or ON. BCM compares status of accessory relay control signal, and power supply position judged by BCM.
6.	Ignition relay	Ignition relay (built in fuse block) is controled by BCM. Ignition relay (built in fuse block) supplies the power switch ON power supply or the power switch ON signal to each ECU when power switch is turned ON. BCM compares status of ignition relay (built in fuse block) control signal and power supply position judged by BCM.
7.	Electric shift control module	Electric shift control module transmits P position signal and P/N position signal to BCM. Refer to "COMPONENT PARTS LOCATION " for detailed installation location.
