PRECAUTIONS FOR KEY REGISTRATION
• The ID registration is a procedure that erases the cu
rrent NATS ID once, and then registers a new ID. There-
fore before starting the registration operation, collect all registered Intelligent Keys from the customer.
• When registering the Intelligent Key, perform only one procedure to simultaneously register both IDs (NATS
ID and Intelligent Key ID).
SECURITY INDICATOR LAMP
• Security indicator lamp warns that the vehicle is equipped with NATS.
• Security indicator lamp always blinks when the i gnition switch is in any position other than ON.
NOTE:
Because security indicator lamp is highly efficient, the battery is barely affected.
ENGINE START OPERATION WHEN INTELLIGENT KEY IS CONTACTED TO PUSH-BUTTON IG-
NITION SWITCH
1. When brake pedal is depressed while selector lever is in the P position the BCM activates NATS antenna amp. that is located behind push-button ignition switch.
2. When Intelligent Key (transponder built-in) backsi de is contacted to push-button ignition switch, BCM
starts NATS ID verification between BCM and Intelligent Key (transponder built-in) via NATS antenna
amp.
3. When NATS ID verification result is OK, buzzer in combination meter sounds and BCM transmits the result to ECM.
4. BCM turns ACC relay ON and transmits ignition power supply ON signal to IPDM E/R.
5. IPDM E/R turns the ignition relay ON and starts the ignition power supply.
6. IPDM E/R turns the starter control relay ON for engine starting in advance.
7. BCM detects that the selector leve r position and brake pedal operation condition.
8. BCM transmits starter request signal to IPDM E/R and turns the starter relay ON if BCM judges that the
engine start condition* is satisfied.
9. Power supply is supplied through the starter relay and the starter control relay to operate the starter motor.
10. When BCM receives feedback signal from ECM indica ting that the engine is started, BCM transmits a
stop signal to IPDM E/R and stops cranking by turning off the starter motor relay. (If engine start is unsuc-
cessful, cranking stops automatically within 5 seconds.)
*: For the engine start condition, refer to “IGN ITION SWITCH POSITION CHANGE TABLE BY PUSH-BUT-
TON IGNITION SWITCH OPERATION” below.
IGNITION SWITCH POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERA-
TION
The ignition switch position can be changed by the following operations.
NOTE:
• When an Intelligent Key is within the detection area of inside key antenna or when Intelligent Key backside is
contacted to push-button ignition switch, it is equivalent to the operations below:
• When starting the engine, the BCM monitors under the engine start conditions:
- Brake pedal operation condition
- Selector lever position
- Vehicle speed
Vehicle speed: less than 4 km/h (2.5 MPH)
