SYSTEM DESCRIPTION
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.
- 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 ignition 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
IGNITION
SWITCH
- 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.
- When Intelligent Key (transponder built-in) backside is contacted to
push-button ignition switch, BCM
starts NATS ID verification between BCM and Intelligent Key (transponder
built-in) via NATS antenna
amp.
- When NATS ID verification result is OK, buzzer in combination meter
sounds and BCM transmits the
result to ECM.
- BCM turns ACC relay ON and transmits ignition power supply ON signal to
IPDM E/R.
- IPDM E/R turns the ignition relay ON and starts the ignition power
supply.
- IPDM E/R turns the starter control relay ON for engine starting in
advance.
- BCM detects that the selector lever position and brake pedal operation
condition.
- BCM transmits starter request signal to IPDM E/R and turns the starter
relay in IPDM E/R ON if BCM
judges that the engine start condition* is satisfied.
- Power supply is supplied through the starter relay and the starter
control relay to operate the starter motor.
- When BCM receives feedback signal from ECM indicating 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 unsuccessful,
cranking stops automatically within 5 seconds.)
*: For the engine start condition, refer to "IGNITION SWITCH POSITION
CHANGE TABLE BY PUSH-BUTTON
IGNITION SWITCH OPERATION" below.
IGNITION SWITCH POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH
OPERATION
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)


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