Operation When Intelligent Key Is Carried
- When the power switch is pressed, BCM activates the inside key antenna and transmits the request signal to the Intelligent Key.
- The Intelligent Key receives the request signal and transmits the Intelligent Key ID signal to BCM.
- BCM receives the Intelligent Key ID signal via remote keyless entry receiver, and verifies it with the registered ID.
- BCM turns ACC relay ON and transmits ON power supply signal to IPDM E/R if the verification results are OK.
- IPDM E/R turns the ignition relay ON to start ON power supply.
- BCM detects that the shift position and brake pedal operating condition.
- BCM transmits READY signal to VCM if BCM judges that the READY set condition* is satisfied.
*: For READY set condition, refer to "READY SET CONDITION TABLE BY POWER SWITCH OPERATION" below.
NOTE:- 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 power 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 VCM indicating that the vehicle is set to READY, BCM stops transmitting READY signal.
