Operation When Intelligent Key Is Contacted To Push-Button Ignition Switch

Models with steering lock unit

1. When brake pedal is depressed while selector lever is in the P position, BCM activates NATS antenna amp. which is located behind push-button ignition switch.
2. When Intelligent Key (transponder built-in) backside is contacted to push-button ignition switch, BCM starts IVIS (NATS) ID verification between BCM and Intelligent Key (transponder built-in) via NATS antenna amp.
3. When IVIS (NATS) ID verification result is OK, buzzer in combination meter sounds and BCM transmits the result to ECM.
4. When push-button ignition switch is pressed, BCM transmits steering unlock signal to steering lock unit and IPDM E/R.
5. IPDM E/R turns steering lock relay ON to supply power source to the steering lock unit.
6. The steering lock is released.
7. BCM transmits the power supply stop signal to IPDM E/R when detecting that the steering lock is in the unlock position.
8. IPDM E/R turns steering lock relay OFF to stop power supply to the steering lock unit.
9. BCM turns ACC relay ON and transmits ignition power supply ON signal to IPDM E/R.
10. IPDM E/R turns the ignition relay ON to start the ignition power supply.
11. BCM detects that the selector lever position and brake pedal operating condition.
12. BCM transmits READY signal to HPCM if BCM judges that the READY set condition* is satisfied.

    *: For READY set condition, refer to "READY SET CONDITION TABLE BY PUSH-BUTTON IGNITION SWITCH OPERATION " below.

    CAUTION:

    • If a malfunction is detected in the Intelligent Key system, "I-KEY system fault" on information display appears. In this case, BCM does not transmits READY signal.
    • When the Intelligent Key is carried outside of the vehicle (inside key antenna detection area) while the ignition switch position is ACC or ON, BCM does not transmits READY signal even if READY set condition* is satisfied.
13. When BCM receives feedback signal from HPCM indicating that the vehicle is set to READY, BCM stops transmitting READY.
