Operation When Intelligent Key Is Inserted Into Key Slot
WARNING: This page is about a different car, the 2011 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.
- When Intelligent Key is inserted into key slot, BCM activates the NATS antenna amp. that is integrated into key slot to transmit the request signal to Intelligent Key.
- Intelligent Key receives the request signal and transmits the Intelligent Key ID signal to BCM.
- BCM receives the Intelligent Key ID signal via NATS antenna amp. and verifies it with the registered ID.
- If the verification result is OK, BCM turns ACC relay ON and transmits the ignition power supply ON signal to IPDM E/R.
- IPDM E/R turns ignition relay ON and starts the ignition power supply.
- BCM detects that selector lever is in the P or N position.
- BCM transmits the starter request signal via CAN communication to IPDM E/R and turns starter relay in IPDM E/R ON if BCM judges that the engine start condition* is satisfied.
- IPDM E/R turns starter control relay ON when receiving the starter request signal.
- Battery power is supplied through starter relay and starter control relay to operate starter motor.
- When BCM received feedback signal from ECM indicating that the engine is started, BCM transmits a stop signal to IPDM E/R and stops the cranking by turning OFF starter motor relay. (If the engine start is unsuccessful, the cranking operation stops automatically within 5 seconds.)
*: For the engine start condition, refer to "IGNITION SWITCH POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERATION ".
