Component

Function

1.

IPDM E/R (Intelligent Power Distribution Module Engine Room)

• IPDM E/R detects push-button ignition switch status, and transmits push-button ignition switch status signal (CAN) to BCM.
• IPDM E/R receives ignition relay-1 (IPDM E/R) control signal and push-button ignition switch ON signal (CAN) from BCM, and controls ignition relay-1.

Refer to System Description .

2.

BCM (Body Control Module)

• BCM controls power distribution system.
• BCM judges push-button ignition switch status and vehicle condition.
• BCM checks push-button ignition switch status internally.

Refer to System Description .

3.

Push-button ignition switch

Refer to Push-Button Ignition Switch .

4.

Accessory relay-1 [in fuse block (J/B)]

• Accessory relay-1 is controlled by BCM.
• Accessory relay-1 supplies accessory power supply or push-button ignition switch ON signal to each ECU when the push-button ignition switch is ON.
• BCM compares status of accessory relay-1 control signal, and push-button ignition switch status judged by BCM.

5.

Ignition relay-2 [in fuse block (J/B)]

• Ignition relay-2 is controlled by BCM.
• Ignition relay-2 supplies ignition ON power supply or push-button ignition switch ON signal to each ECU and system when the push-button ignition switch is ON.
• BCM compares status of ignition relay-2 control signal and push-button ignition switch status judged by BCM.
• BCM monitors ignition relay-2 operating status by ignition relay-2 feedback signal.

6.

Front blower motor relay [in fuse block (J/B)]

• Front blower motor relay is controlled by BCM.
• Front blower motor relay supplies push-button ignition switch ON power supply or push-button ignition switch ON signal to the air conditioning system when the push-button ignition switch is ON.
• BCM compares status of front blower motor relay control signal and push-button ignition switch status judged by BCM.
