- 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 (inside IPDM E/R)
- Ignition relay-1
- ACC relay
- Blower relayNOTE: The engine switch operation changes due to the conditions of brake pedal, selector lever and vehicle speed.
