Operation When Intelligent Key Is Contacted To Push-Button Ignition Switch
- 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.
- 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.
- When IVIS (NATS) ID verification result is OK, buzzer in combination meter sounds and BCM transmits the result to ECM.
- BCM turns ACC relay ON and transmits ignition power supply ON signal to IPDM E/R.
- IPDM E/R turns the ignition relay ON to start the ignition power supply.
- BCM detects that the selector lever position and brake pedal operating condition.
- 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.
- When BCM receives feedback signal from HPCM indicating that the vehicle is set to READY, BCM stops transmitting READY.
