1.

The Intelligent Key Unit receives the push-button ignition switch input and transmits the signal to the BCM and IPDM E/R via CAN communication. Refer to Component Parts Location for detailed installation location.

2.

Refer to Component Parts Location for detailed installation location.

3.

The IPDM E/R receives ignition relay-1 (IPDM E/R) control signal and push-button ignition switch ON signal via CAN communication from the Intelligent Key unit, and controls the ignition relay-1 (built into IPDM E/R).

4.

The BCM controls the power distribution system. The BCM judges the ignition status and vehicle condition. The BCM checks the ignition status internally.

5.

Refer to Push-Button Ignition Switch .

6.

The CVT shift selector (park position switch) sends the park position switch signal to the BCM.

7.

The transmission range switch transmits P (park) and N (neutral) signals to the IPDM E/R.

8.

The park/neutral position (PNP) switch transmits the N (neutral) signal to the IPDM E/R.

9.

The BCM controls the starter cut relay according to the request signal from the Intelligent Key unit and push-button ignition switch.

10.

The stop lamp switch detects that the brake pedal is depressed and transmits the signal to the BCM.

11.

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

12.

The ignition relay-3 is controlled by the BCM. The Ignition relay-3 supplies ignition ON power supply or ignition ON signal to each ECU and system when the push-button ignition is ON. The BCM compares the status of the ignition relay-3 control signal and ignition status judged by the push-button ignition switch. The BCM monitors the ignition relay-3 operating status by the ignition relay-3 feedback signal.

13.

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