No.	Component	Description
1	Push-button ignition switch1	Push-button ignition switch (push switch) is pressed (ON), and transmits status signal to BCM and IPDM E/R.
1	Ignition switch2	Ignition switch is turned to ON, and transmits status signal to BCM and IPDM E/R.
2	IPDM E/R	IPDM E/R detects push-button ignition switch1 or ignition switch2 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)
3	BCM	BCM controls power distribution system. BCM judges ignition position and vehicle condition. BCM checks ignition position internally.
4	Ignition relay-2 (in fuse block)	Ignition relay-2 is controlled by BCM. Ignition relay-2 supplies ignition ON power supply or ignition ON signal to each ECU and system when ignition is turned ON. BCM compares status of ignition relay-2 control signal and ignition position judged by BCM. BCM monitors ignition relay-2 operating status by ignition relay-2 feedback signal.
5	Front blower motor relay (in fuse block)	Front blower motor relay is controlled by BCM. Front blower motor supplies ignition ON power supply or ignition ON signal to air conditioning system when ignition is turned ON. BCM compares status of front blower motor relay control signal and ignition position judged by BCM.
6	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.

SYSTEM DESCRIPTION

With Intelligent Key System

PDS (POWER DISTRIBUTION SYSTEM) is the system that the BCM controls with the operation of the push-button ignition switch to perform the power distribution to each power circuit. This system is used instead of the mechanical power supply changing mechanism with the operation of the conventional key cylinder.
The push-button ignition switch can be operated when Intelligent Key is in the following conditions:

Intelligent Key is in the detection area of the inside key antenna.
Intelligent Key backside is contacted to push-button ignition switch.

The push-button ignition switch operation is input to BCM as a signal. BCM changes the power supply position according to the status and operates the following relays to supply power to each power circuit.

Ignition relay-1
Ignition relay-2
Accessory relay-1
Front blower motor relay

NOTE: The engine switch operation changes due to the conditions of brake pedal, selector lever and vehicle speed.

The power supply position can be confirmed with the lighting of the indicator in the push-button ignition switch.

With Remote Keyless Entry System

PDS (POWER DISTRIBUTION SYSTEM) is the system that the BCM controls with the operation of the ignition switch to perform the power distribution to each power circuit.
The ignition switch operation is input to the BCM as a signal. BCM changes the power supply position according to the status and operates the following relays to supply power to each power circuit:

Ignition relay-1
Ignition relay-2
Accessory relay-1
Front blower motor relay

IGNITION BATTERY SAVER SYSTEM

When all the following conditions are met for 30 minutes, the ignition battery saver system will cut off the power supply to prevent battery discharge.

The ignition is in the ON position
All doors are closed
Selector lever is in the P (park) position

Reset Condition of Ignition Battery Saver System

In order to prevent the battery from discharging, the ignition battery saver system will cut off the power supply when all doors are closed, the selector lever is in P (park) position and the ignition is left in the ON position for 30 minutes.

Opening any door
Operating door request switch on door handle
Operating Intelligent Key (with Intelligent Key system)
Operating keyfob (with remote keyless entry system)

POWER SUPPLY POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERATION (WITH INTELLIGENT KEY SYSTEM)

The power supply position changing operation can be performed with the following operations.

NOTE:

When an Intelligent Key is within the detection area of inside key antenna and when Intelligent Key backside is contacted to push-button ignition switch, it is equivalent to the operations below.
When starting the engine, the BCM monitors under the engine start conditions:

Brake pedal operating condition
Selector lever position
Vehicle speed

Vehicle speed: less than 4 km/h (2.5 MPH)

Vehicle speed: 4 km/h (2.5 MPH) or more

Emergency stop operation

Press and hold the push-button ignition switch for 2 seconds or more.
Press the push-button ignition switch 3 times or more within 1.5 seconds.
