SYSTEM DESCRIPTION

• The READY set function of Intelligent Key system makes it possible to set the vehicle to READY without using the Intelligent Key, based on the electronic ID verification. The electronic ID verification is performed between Intelligent Key unit and Intelligent Key when the power switch is pressed while the Intelligent Key is within the detection area of NATS antenna amp.

  NOTE:

  The driver should carry the Intelligent Key at all times.

• Intelligent Key has 2 IDs (Intelligent Key ID and NATS ID). It can perform the door lock/unlock operation and the power switch operation when the registered Intelligent Key is carried.

• If the ID is successfully verified, power switch operation can be available, and the Nissan Ariya vehicle can be set to READY.

• Up to 4 Intelligent Keys can be registered upon request from the customer.

  NOTE:

  For any functions other than the READY set 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. 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 power switch while push switch is pressed. If verification result is OK, the Nissan Ariya vehicle can be set to READY.

OPERATION WHEN INTELLIGENT KEY IS CARRIED

1. When the power switch is pressed, Intelligent Key unit activates the NATS antenna amp. and transmits the request signal to the Intelligent Key.

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

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

4. BCM transmits power switch ON signal to IPDM E/R.

5. When power switch is turned ON, Intelligent Key unit starts communication with inverter (front) and performs the ID verification between Intelligent Key unit and inverter (front). If the verification result is OK, the Nissan Ariya vehicle can be set to READY.

6. BCM detects that the brake pedal operating condition.

7. VCM detects that the shift position.

8. 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.

   CAUTION:

   • If a malfunction is detected in the Intelligent Key system, Intelligent Key system malfunction on information display appears. In this case, BCM does not transmits READY signal.

   • When the Intelligent Key is carried outside of the Nissan Ariya vehicle (NATS antenna amp. detection area) while the power switch position is ON, BCM does not transmits READY signal even if READY set condition* is satisfied.

OPERATION RANGE

Vehicle can be set to READY when Intelligent Key is inside the vehicle. However, sometimes vehicle may not be set to READY when Intelligent Key is on instrument panel or in glove box.

READY SET CONDITION TABLE BY POWER SWITCH OPERATION

The vehicle can be set to READY by the following operations.

NOTE:

• When an Intelligent Key is within the detection area of NATS antenna amp. and when Intelligent Key backside is contacted to power switch, it is equivalent to the operations below.

• When setting the Nissan Ariya vehicle to READY, the Intelligent Key unit monitors READY set conditions,

  • Brake pedal operating condition

  • Shift position

  • Nissan Ariya Vehicle speed

Vehicle speed: less than 4 km/h (2.5 MPH)

NOTE:

If the Intelligent Key unit cannot detect that the Intelligent Key is in the Nissan Ariya vehicle, power switch cannot be turned OFF.

Vehicle speed: 4 km/h (2.5 MPH) or more

Emergency stop operation

• Press and hold the power switch for 2 seconds or more.

• Press the power switch 3 times or more within 1.5 seconds.
