SYSTEM DESCRIPTION

• The engine start function of Intelligent Key system makes it possible to start and stop the engine without using the key, based on the electronic ID verification. The electronic ID verification is performed between Intelligent Key unit and Intelligent Key when the push-button ignition switch is pressed while the Intelligent Key is within the detection area of inside key antenna.

  NOTE:

  The driver should carry the Intelligent Key at all times.

• Intelligent Key have ID (Key ID). It can perform the door lock/unlock operation and the push-button ignition switch operation when the registered Intelligent Key is carried.

• If the ID is successfully verified, when push-button ignition switch is pressed, engine can be started.

• Up to 4 Intelligent Keys can be registered (Including the standard Intelligent Key) upon request from the customer.

  NOTE:

  For any functions other than engine start function of Intelligent Key system. Refer to System Description.

PRECAUTIONS FOR INTELLIGENT KEY SYSTEM

The transponder (the chip for NATS ID verification) is integrated into the Intelligent Key. It is integrated into the mechanical key. Therefore, ID verification cannot be performed by mechanical key only.

In that case, NATS ID verification can be performed when Intelligent Key backside is contacted to push-button ignition switch while brake pedal is depressed. If verification result is OK, engine can be started.

OPERATION WHEN INTELLIGENT KEY IS CARRIED

1. When the push-button ignition switch is pressed, the Intelligent Key unit activates the inside key antenna and transmits the request signal to the Intelligent Key.

2. The Intelligent Key receives the request signal and transmits the NATS ID signal to the Intelligent Key unit.

3. Intelligent Key unit receives the NATS ID signal verifies it with the registered ID.

4. 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.

5. When ECM detects that the start engine conditions* are satisfied, it transmits a starter cut relay request signal to BCM.

6. When BCM receives a starter cut relay request signal from ECM, the starter cut relay is turned ON.

7. When starter cut relay is turned ON, IPDM E/R turns ON the starter relay and drives the starter motor.

8. When BCM receives an engine status signal from ECM, it turns the starter relay and starter cut relay OFF and stops cranking.

   CAUTION:

   When the Intelligent Key is carried outside of the Nissan Ariya vehicle (outside key antenna detection area) while the power supply is in the ON position, even if the engine start condition* is satisfied, the engine cannot be started.

*: For the engine start condition, refer to “IGNITION SWITCH POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERATION”.
