Engine Start Operation When Intelligent Key Is Contacted To Push-Button Ignition Switch
WARNING: This page is about a different car, the 2011 Nissan Juke. However, it is still accessible from the selected car via links, so may be relevant.
- When brake pedal is depressed, while selector lever is in the P position (CVT models), BCM activates NATS antenna amp. that is located behind push-button ignition switch.
- When Intelligent Key (transponder built-in) backside is contacted to push-button ignition switch, BCM starts NVIS (NATS) ID verification between BCM and Intelligent Key (transponder built-in) via NATS antenna amp.
- When the NVIS (NATS) ID verification result is OK, buzzer in combination meter sounds and BCM transmits the result to ECM.
- When push-button ignition switch is pressed, BCM turns ACC relay ON and transmits ignition power supply ON signal to IPDM E/R.
- IPDM E/R turns the starter control relay ON for engine starting in advance.
- 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 (CVT models), or clutch pedal operation condition (M/T models).
- BCM transmits starter request signal to IPDM E/R and turns the starter relay in IPDM E/R ON if BCM judges that the engine start condition* is satisfied.
- Power supply is supplied to the starter motor through the starter relay and the starter control relay.
- When BCM receives feedback signal from ECM indicating that the engine is started, BCM transmits a stop signal to IPDM E/R to stop cranking by turning off the starter motor relay. (If engine start is unsuccessful, cranking stops automatically within 5 seconds.)
