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

When brake pedal is depressed while selector lever is in the P position (CVT models), or clutch pedal is depressed (M/T models), Intelligent Key unit 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, Intelligent Key unit starts NATS ID verification between Intelligent Key unit and Intelligent Key (transponder built-in) via NATS antenna amp.
When NATS ID verification result is OK, buzzer in combination meter sounds.
When the ignition switch is turned to ON, Intelligent Key unit performs ID verification with the ECM. When the result is OK, engine start is permitted.
BCM detects that the selector lever position and brake pedal operation condition.
When ECM detects that the start engine conditions* are satisfied, it transmits a starter control relay request signal to BCM.
When BCM receives a starter control relay request signal from ECM, the starter control relay is turned ON.
When starter control relay is turned ON, IPDM E/R turns ON the starter relay and drives the starter motor.
When BCM receives an engine status signal from ECM, it turns the starter relay and starter control relay OFF and stops cranking.
