  1. When the push-button ignition switch is pressed and brake pedal depressed, the BCM signals the inside key antenna and transmits the request signal to the Intelligent Key.
  2. The Intelligent Key receives the request signal and transmits the Intelligent Key ID signal to the BCM via the remote keyless entry receiver.
  3. The BCM receives the Intelligent Key ID signal and verifies it with the registered ID.
  4. BCM turns ACC relay ON and transmits the ignition power supply ON signal to IPDM E/R.
  5. IPDM E/R turns the ignition relay ON and starts the ignition power supply.
  6. BCM confirms that the shift position is P.
  7. BCM transmits the hybrid system start request signal via hardwire to Hybrid Vehicle Control ECU. If BCM judges that the hybrid system start condition is satisfied.
