SYSTEM DESCRIPTION

• The NISSAN VEHICLE IMMOBILIZER SYSTEM (NVIS) prevents the vehicle from being set to READY by Intelligent Key whose ID is not registered to the Nissan Ariya vehicle (Intelligent Key unit). It has higher protection against auto theft involving the duplication of mechanical keys.

• The mechanical key integrated in the Intelligent Key cannot set the Nissan Ariya vehicle to READY. When the Intelligent Key battery is discharged, the NATS ID verification is performed between the transponder integrated with Intelligent Key and Intelligent Key unit via NATS antenna amp. when the Intelligent Key backside is connected to power switch after power switch pressed. If the verification result is OK, the Nissan Ariya vehicle can be set to READY by the power switch operation.

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

• When replacing VCM, Intelligent Key unit, BCM, inverter (front) or Intelligent Key, the specified procedure (Initialization and registration) using CONSULT is required.

PRECAUTIONS FOR KEY REGISTRATION

The ID registration is a procedure that erases the current NATS ID once, and then registers a new ID. Therefore before starting the registration operation, collect all registered Intelligent Keys from the customer.

OPERATION WHEN INTELLIGENT KEY IS CONTACTED TO POWER SWITCH

1. When power switch is pressed while shift position is in the P position, Intelligent Key unit activates NATS antenna amp. is integrated in power switch.

2. When Intelligent Key (transponder built-in) backside is contacted to power switch, Intelligent Key unit starts NATS ID verification between Intelligent Key unit and Intelligent Key (transponder built-in) via NATS antenna amp.

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

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

5. BCM detects that the brake pedal operating condition.

6. VCM detects that the shift position.

7. BCM transmits READY signal to VCM if BCM judges that the READY set condition* is satisfied.

*:For the READY set conditions, refer to “READY SET CONDITION TABLE BY POWER SWITCH OPERATION” below.

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
